IP Address verification in REST API with SpringSecurity - java

I have Spring Boot application with configured SpringSecurity. It uses token generated by UUID.randomUUID().toString(), returned by method login in UUIDAuthenticationService class in AuthUser object. Authorized users are kept in LoggedInUsers class. When I'm sending request to API token is verified by method findByToken in UUIDAuthenticationService class.
Lastly I added timeout for token verification. Now I want to add ip address verification. If user is logged in from address X.X.X.X (which is kept in AuthUser object) he should be authorized with his token only form address X.X.X.X. How to do it?

}
I thought about creating method findByTokenAndIp in UUIDAuthenticationService, but I don't know how to find ip address of user sending request and how to get ip address while logging in login method in UUIDAuthenticationService (I need it while I'm creating AuthUser object).

You had access to HttpServletRequest request in your filter so you can extract the IP from it.
See https://www.mkyong.com/java/how-to-get-client-ip-address-in-java/
After having the IP, you can deny the request anyway that you want!

I would briefly do the following steps:
save the IP in the UUIDAuthenticationService. You can add HttpServletRequest request as a param, if you're using a controller/requestmapping, because it's auto-injected:
#RequestMapping("/login")
public void lgin(#RequestBody Credentials cred, HttpServletRequest request){
String ip = request.getRemoteAddr();
//...
}
Within the authentication filter, use the IP as the "username" for the UsernamePasswordAuthenticationToken and the token as the "password". There is also already the HttpServletRequest request that gives you the IP by getRemoteAddr().
It's also possible to create an own instance of AbstractAuthenticationToken or even UsernamePasswordAuthenticationToken, which explictly holds an IP or even the request for the authentication-manager.
Then, you just need to adapt the changes to your retrieveUser method.

I modified controller to get ip address with HttpServletRequest parameter and add parameter ipAddress to login method.
#PostMapping("/login")
public AuthUser login(InputStream inputStream, HttpServletRequest request) throws Exception {
final String ipAddress = request.getRemoteAddr();
if (ipAddress == null || ipAddress.equals("")) {
throw new Exception("Nie udało się ustalić adresu IP klienta");
}
Login login = loginMgr.prepareLogin(inputStream);
return authentication
.login(login.getUsername(), login.getPasword(), ipAddress);
}
And modified method retrieveUser in TokenAuthenticationProvider
#Override
protected UserDetails retrieveUser(final String username, final UsernamePasswordAuthenticationToken authentication) {
System.out.println("Verification: "+authentication.getPrincipal()+" => "+authentication.getCredentials());
final Object token = authentication.getCredentials();
final String ipAddress= Optional
.ofNullable(authentication.getPrincipal())
.map(String::valueOf)
.orElse("");
return Optional
.ofNullable(token)
.map(String::valueOf)
.flatMap(auth::findByToken)
.filter(user -> user.ipAddress.equals(ipAddress)) // weryfikacja adresu ip
.orElseThrow(() -> new UsernameNotFoundException("Cannot find user with authentication token=" + token));
}
And it works. Thans for help.

Can I generate a JWT for my Spring Security app without have a user?

I want to generate a JWT with expiration date for people to access the system without have to register and create a user. Is this posible? I have tried with JwtTokenProvider but it needs a LoginRequest to work also with Jwts.builder() also needs a user.
if you want to use spring security you can create security configration and extends WebSecurityConfigurerAdapter. Then important point is custom provider.
#Configuration
#EnableWebSecurity
#EnableGlobalMethodSecurity(prePostEnabled = true, securedEnabled = true)
public class SecurityConfiguration extends WebSecurityConfigurerAdapter {
#Autowired
private CustomAuthenticationProvider customAuthenticationProvider;
#Autowired
private JWTConfigurer securityConfigurerAdapter;
#Autowired
public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
//you can write customAuth provider
auth.authenticationProvider(customAuthenticationProvider);
}
#Override
public void configure(WebSecurity web) throws Exception {
//Some ignore etc.
}
#Override
protected void configure(HttpSecurity http) throws Exception {
http
.exceptionHandling()
.authenticationEntryPoint(authenticationEntryPoint)
.and()
.csrf()
.disable().and()
.headers()
.frameOptions()
.disable()
.and()
.sessionManagement()
.sessionCreationPolicy(SessionCreationPolicy.STATELESS)
.and()
.authorizeRequests()
//important here
.antMatchers("/api/v1/authentication/**").permitAll()
.anyRequest().authenticated()
.and()
.apply(securityConfigurerAdapter);
}
#Bean
#Override
public AuthenticationManager authenticationManagerBean() throws Exception {
return this.authenticationManager();
}
}
This is Filter class which extends genericFilterBean. Every request is monitored in this class
You will check to it is right token
I create token TokenProvider class and depend into JWTFilter then use valideToken method.
if token is sended and not validate then throw exception
if token is not sended then go super method so the flow is continue and works auth.authenticationProvider. Spring knows to start customAuthenticationProvider behind the scene becouse of you set into SecurityConfiguration class
#Component
public class JWTFilter extends GenericFilterBean {
private final Logger log = LoggerFactory.getLogger(JWTFilter.class);
#Autowired
private TokenProvider tokenProvider;
#Autowired
private MessageSource msgSource;
#Override
public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain)
throws IOException, ServletException {
try {
HttpServletRequest httpServletRequest = (HttpServletRequest) servletRequest;
//Resolve method is optional what you want to use
String jwt = resolveToken(httpServletRequest);
if (StringUtils.hasText(jwt)) {
//token validation is important becouse of expires date into token
// and you will check expired date
if (this.tokenProvider.validateToken(jwt)) {
String jwtMd5 = DigestUtils.md5Hex(jwt);
MDC.put("jwt",jwtMd5);
Authentication authentication = this.tokenProvider.getAuthentication(jwt);
SecurityContextHolder.getContext().setAuthentication(authentication);
}
}
filterChain.doFilter(servletRequest, servletResponse);
}catch(Exception ex){
handleException((HttpServletResponse) servletResponse,ex);
}
}
private String resolveToken(HttpServletRequest request) {
String bearerToken = request.getHeader(JWTConfigurer.AUTHENTICATION_HEADER);
if (StringUtils.hasText(bearerToken) && bearerToken.startsWith("Bearer ")) {
String jwt = bearerToken.substring(7, bearerToken.length());
return jwt;
}
String jwt = request.getParameter(JWTConfigurer.AUTHENTICATION_TOKEN);
if (StringUtils.hasText(jwt)) {
return jwt;
}
return null;
}
}
You can use this class for create token or validate token
you define expire date for token expiration into create method.
#Component public class TokenProvider {
private final Logger log = LoggerFactory.getLogger(TokenProvider.class);
private static final String AUTHORITIES_KEY = "auth";
private static final String WTS_USER_ID = "wtsUserId";
private static final String CHANNEL_PERMISSIONS = "channelPermissions";
private static final String APP_ROLES = "appRoles";
private String secretKey;
private long tokenValidityInSeconds;
#Autowired private ApplicationProperties applicationProperties;
#PostConstruct public void init() {
this.tokenValidityInSeconds = 1000;
}
public String createToken(Authentication authentication, Boolean rememberMe) { List<String> authorities = authentication.getAuthorities().stream().map(authority -> authority.getAuthority())
.collect(Collectors.toList());
//Token creation format is this
// token will be three part important parts are claims and sign
// claims refers to body to use datas
// sign will use to validation
return Jwts.builder().setSubject(authentication.getName()).claim(AUTHORITIES_KEY, authorities)
.claim(WTS_USER_ID, ((JWTAuthentication) authentication).getWtsUserId())
.claim(CHANNEL_PERMISSIONS, ((JWTAuthentication) authentication).getChannelPermissions())
.claim(APP_ROLES, ((JWTAuthentication) authentication).getAppRoles())
.signWith(SignatureAlgorithm.HS512, secretKey).setExpiration(tokenValidityInSeconds).compact(); }
#SuppressWarnings("unchecked") public Authentication getAuthentication(String token) { Claims claims = Jwts.parser().setSigningKey(secretKey).parseClaimsJws(token).getBody();
List<String> list = (List<String>) claims.get(AUTHORITIES_KEY); Collection<? extends GrantedAuthority> authorities = list.stream()
.map(authority -> new SimpleGrantedAuthority(authority)).collect(Collectors.toList()); Integer wtsUserId = (Integer) claims.get(WTS_USER_ID); List<String> appRoles = (List<String>) claims.get(APP_ROLES);
ObjectMapper objectMapper = new ObjectMapper(); List<ChannelPermission> channelPermissions = objectMapper.convertValue(claims.get(CHANNEL_PERMISSIONS),
new TypeReference<List<ChannelPermission>>() {
});
return new JWTAuthentication(token, wtsUserId, claims.getSubject(), authorities, channelPermissions, appRoles); }
public boolean validateToken(String authToken) {
try {
Jwts.parser().setSigningKey(secretKey).parseClaimsJws(authToken);
return true;
} catch (SignatureException e) {
log.info("Invalid JWT signature: " + e.getMessage());
return false;
} } }
This is controller who anonymous people get a JWT token .You can give a new JWT token all request and this JWT has expires date becouse of you set a expiration date into provider class.
#RequestMapping(value = "/login", method = RequestMethod.POST, produces = MediaType.APPLICATION_JSON_VALUE)
public ApiResponse login(#RequestBody #Validated AuthenticationRequestDTO authenticationRequest) {
Authentication authentication = this.authenticationManager.authenticate(new JWTAuthentication(
RandomUid, RandomPwd, "anonymous"));
SecurityContextHolder.getContext().setAuthentication(authentication);
String token = tokenProvider.createToken(authentication, false);
return new ApiResponse(ApiResponseStatus.SUCCESS, new AuthenticationResponseDTO(token));
}

I can not retrieve the current custom user object from Spring Security Context

I'm using LDAP authentication provider (active directory) + JWT authorization filter.
I have my custom user object implementing UserDetails, also my user service extends UserDetailsService. But when I do:
Usuario principal = (Usuario) SecurityContextHolder.getContext().getAuthentication().getPrincipal();
Principal is just a string (the username), not my user object.
This is my configuration:
SecurityConfig:
#Configuration
#EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
private final LdapProperties ldapProperties;
private final LdapUserMapper ldapUserMapper;
private final UserService userService;
public SecurityConfig(LdapProperties ldapProperties, LdapUserMapper ldapUserMapper, UserService userService) {

urls,
ldapProperties.getBase()
);
provider.setUserDetailsContextMapper(ldapUserMapper);
provider.setConvertSubErrorCodesToExceptions(true);
// comment to connect as anonymous
provider.authenticate(
new UsernamePasswordAuthenticationToken(ldapProperties.getUsername(), ldapProperties.getPassword())
);
return provider;
}
}
LdapUserMapper:
#Component
public class LdapUserMapper implements UserDetailsContextMapper {
private final UserService userService;
#Autowired
public LdapUserMapper(UserService userService) {
this.userService = userService;
}
#Override
public UserDetails mapUserFromContext(DirContextOperations ctx, String username, Collection<? extends GrantedAuthority> authorities) {

//TODO compare roles ? set bloqueado ? ...
return result;
}
#Override
public void mapUserToContext(UserDetails userDetails, DirContextAdapter dirContextAdapter) {
}
}
It was my authorization filter.
#Override
protected void doFilterInternal(HttpServletRequest req,
HttpServletResponse res,
FilterChain chain) throws IOException, ServletException {
String token = req.getHeader("Authorization");
if (token != null && token.startsWith("Bearer ")) {
token = token.replace("Bearer ", "");
Authentication authentication = getAuthentication(token);
SecurityContextHolder.getContext().setAuthentication(authentication);
}
chain.doFilter(req, res);
}
private UsernamePasswordAuthenticationToken getAuthentication(final String token) {
try {
DecodedJWT decodedToken = JWT.require(Algorithm.HMAC512(jwtSecret)).build().verify(token);
String username = decodedToken.getSubject();
return new UsernamePasswordAuthenticationToken(username , null, new ArrayList<>());
} catch (JWTVerificationException ex) {
log.error(ex.getMessage());
}
return null;
}
I wasn't aware that I only was passing the username as the Principal object. So I changed it to this:
Usuario usuario = (Usuario) userService.loadUserByUsername(decodedToken.getSubject());
I also removed
auth.userDetailsService(userService);
From AuthenticationManagerBuilder config. That was wrong. My auth provider is LDAP, not the DB.

Understanding jwt and login logic

I am new to jwt and im using some resources from the net to help me get to understand jwt properly , I am able now to generate a token and access a resource that requires authorisation, first , i have a controller like
#RequestMapping("/token")
public class TokenController {
private JwtGenerator jwtGenerator;
public TokenController(JwtGenerator jwtGenerator) {
this.jwtGenerator = jwtGenerator;
}
#PostMapping
public String generate(#RequestBody final JwtUser jwtUser) {
return jwtGenerator.generate(jwtUser);
}
excuse me for i will be posting a lot of code.I am using postman for testing
so when i pass this as a post
{
"useNe" : "ter",
"paord":"123",
"role":"ain"
} or
{
"username" : "ter",
"is":"123",
"role":"admin"
}
I am generating a token ,it should require a username and password i think before a jwt token should be produced and i want to implement a proper login ,below is the security config and other classes that i have
#EnableWebSecurity
#Configuration
public class SecurityConfig extends WebSecurityConfigurerAdapter {
#Autowired
private JwtAuthenticationProvider authenticationProvider;
#Autowired
private JwtAuthenticationEntryPoint entryPoint;
#Bean
public AuthenticationManager authenticationManagerBean() {
return new ProviderManager(Collections.singletonList(authenticationProvider));
}
#Bean
public JwtAuthenticationTokenFilter authenticationTokenFilter() throws Exception {
JwtAuthenticationTokenFilter filter = new JwtAuthenticationTokenFilter();
filter.setAuthenticationManager(authenticationManager());
// we set success handler so that we overide the default redirection
filter.setAuthenticationSuccessHandler(new JwtSuccessHandler());
return filter;
}
#Override
protected void configure(HttpSecurity http) throws Exception {
http.csrf().disable()
.authorizeRequests().antMatchers("**/rest/**").authenticated()
.and()
.exceptionHandling().authenticationEntryPoint(entryPoint)
.and()
.sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS);
http.addFilterBefore(authenticationTokenFilter(), UsernamePasswordAuthenticationFilter.class);
http.headers().cacheControl();
}
}
how can i create a login that will generate a token , or is that not the standard for jwt , also i want to have two types of role user and admin, admin can access all resources while user can access some , here are other classes
public class JwtAuthenticationTokenFilter extends AbstractAuthenticationProcessingFilter {
public JwtAuthenticationTokenFilter() {
super("/rest/**");
}
#Override
public Authentication attemptAuthentication(HttpServletRequest httpServletRequest,
HttpServletResponse httpServletResponse)
throws AuthenticationException, IOException, ServletException {
String header = httpServletRequest.getHeader("Authorisation");
if (header == null || !header.startsWith("Token")) {
throw new RuntimeException("JWT Token is missing");
}
String authenticationToken = header.substring(6);
JwtAuthenticationToken token = new JwtAuthenticationToken(authenticationToken);
return getAuthenticationManager().authenticate(token);
}
#Override
protected void successfulAuthentication(HttpServletRequest request, HttpServletResponse response, FilterChain chain, Authentication authResult)
throws IOException, ServletException {
super.successfulAuthentication(request, response, chain, authResult);
chain.doFilter(request, response);
}
}
And my jwt generator should this not require a an username and password for login
#Component
public class JwtGenerator {
public String generate(JwtUser jwtUser) {
Claims claims = Jwts.claims()
.setSubject(jwtUser.getUserName());
claims.put("userId", String.valueOf(jwtUser.getId()));
claims.put("role", jwtUser.getRole());
return Jwts.builder()
.setClaims(claims)
.signWith(SignatureAlgorithm.HS512, "youtube")
.compact();
}
}
#Component
public class JwtAuthenticationProvider extends AbstractUserDetailsAuthenticationProvider {
#Autowired
private JwtValidator validator;
#Override
protected void additionalAuthenticationChecks(UserDetails userDetails, UsernamePasswordAuthenticationToken usernamePasswordAuthenticationToken)
throws AuthenticationException {
}
#Override
protected UserDetails retrieveUser(String username, UsernamePasswordAuthenticationToken usernamePasswordAuthenticationToken)
throws AuthenticationException {
JwtAuthenticationToken jwtAuthenticationToken = (JwtAuthenticationToken) usernamePasswordAuthenticationToken;
String token = jwtAuthenticationToken.getToken();
JwtUser jwtUser = validator.validate(token);
if(jwtUser == null){
throw new RuntimeException("user token is incorrect" );
}
List<GrantedAuthority> grantedAuthorities = AuthorityUtils
.commaSeparatedStringToAuthorityList(jwtUser.getRole());
//we return an authenticated user
return new JwtUserDetails(jwtUser.getUserName(),jwtUser.getId(),token , grantedAuthorities);
}
#Override
public boolean supports(Class<?> aClass) {
return (JwtAuthenticationToken.class.isAssignableFrom(aClass));
}
}
How do i go about improving on this and end up with a proper login that generates a jwt and keeps it in headers for every request

Approaches for logout functionality in Spring Boot app (Spring Security + JWT)

I create Spring Boot + Spring Security app with JWT authentication and it works something like this:
client sends username, password to the login endpoint;
server checks if the provided credentials are valid and return a token;
client sends the token with every future request.
It's based on this example and approach for logout functionality which author suggest - just remove JWT token on client-side. I don't think that is good idea, and I'd like to implement it on back-end.
As I understand I need to remove JWT token of user which call logout REST method on server-side, after that when this user will call other REST methods he should get responses with 403 error. I investigated ways how can I add this feature and didn't find any appropriate solution.
Here are details of my implementation (there may be some differences from the example from the link above):

Spring token security with credential security (springboot)

I have a question regarding security implementation on my server. I am making a SpringBoot application which has a control panel like website on it, where 1 single admin inputs needed data and i have managed to secure that part fine like this :
#Configuration
#EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
#Override
protected void configure(HttpSecurity http) throws Exception {
http.antMatcher("/*").authorizeRequests().anyRequest().hasRole("ADMIN")
.and().formLogin().loginPage("/login.jsp")
.failureUrl("/login.jsp?error=1").loginProcessingUrl("/login")
.permitAll().and().logout()
.logoutSuccessUrl("/login.jsp");
}
#Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
// Create a default account
auth.inMemoryAuthentication()
.withUser("admin")
.password("admin")
.roles("ADMIN");
}
Every website url is on /*, and that works fine. The next thing i need to do is to retrieve data from my mobile app and it needs to be secure. urls that the app should use is /rest/**. I have a Student class that stores email(username) and password that is created by that admin on web site. As far as i've read i need token implementation.
How can I implement token authentication?
To implement token based authentication for a mobile app, with Spring Boot and Spring Security.
Create a TokenAuthenticationFilter

Finally Register These in your Security Config
//Leave whatever you had here
#Override

String contentPathDir = String.format("/%s/**", contentPath);
http.csrf().disable()
.sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS)
.and().authorizeRequests()
.antMatchers("/authorization/**", "/public/**", "/management/**", "/health/**", contentPathDir).permitAll()
.antMatchers("/**").authenticated();
}
//Add these two below.
#Override
public void configure(AuthenticationManagerBuilder auth) {
auth.authenticationProvider(apiKeyAuthenticationProvider());
}
#Bean
public TokenAuthenticationProvider apiKeyAuthenticationProvider() {
return new TokenAuthenticationProvider(apiKey);
}
