Apache CXF OAuth2 HTTP Response Splitting via WWW-Authenticate Realm Injection

A CRLF injection vulnerability exists in the OAuth2 AuthorizationUtils class. When constructing the WWW-Authenticate response header, the 'realm' parameter is concatenated without sanitizing Carriage Return CR and Line Feed LF characters. If an attacker can control the realm value, they can injec...

GHSA-F8P7-H97Q-7VX7 Apache CXF OAuth2 Log Injection via Unsanitized Client Identifier

The 'clientId' parameter from incoming HTTP requests is directly concatenated into OAuth2 server log warning messages without sanitizing control characters. This allows an attacker to inject arbitrary content, including fake log entries, into the server's log files. Users are recommended to upgra...

GHSA-83R6-96M8-R52P Apache CXF OAuth2 TOCTOU Race Condition in Refresh Token Processing

A race condition in AbstractOAuthDataProvider allows concurrent requests using the same Refresh Token to bypass single-use semantics and generate multiple valid Access Tokens, when 'recycleRefreshTokens' is set to false. A leaked refresh token can be replayed concurrently by multiple attackers or...

GHSA-542G-M3FX-Q86F Apache CXF has Authentication Bypass in OAuth2 TokenIntrospectionService

An authentication bypass vulnerability exists in the OAuth2 TokenIntrospectionService in Apache CXF. Due to a missing 'throw' keyword in the security context check, the introspection endpoint /services/oauth2/introspect can be accessed by any unauthenticated network attacker. However note that th...

Apache CXF OAuth2 Missing JWT Audience and Issuer Validation in Access Token Validator

The JwtAccessTokenValidator class in Apache CXF fails to validate the 'aud' Audience claims of incoming JWT access tokens. This allows a JWT issued for one Resource Server to be successfully replayed against a completely different Resource Server, leading to Token Confusion/Routing attacks. Users...
