CVE-2022-31690

CVE-2022-31690: spring-security-oauth2-client vulnerable to Privilege Escalation

Spring Security, versions 5.7 prior to 5.7.5, and 5.6 prior to 5.6.9, and older unsupported versions could be susceptible to a privilege escalation under certain conditions. A malicious user or attacker can modify a request initiated by the Client (via the browser) to the Authorization Server which can lead to a privilege escalation on the subsequent approval. This scenario can happen if the Authorization Server responds with an OAuth2 Access Token Response containing an empty scope list (per RFC 6749, Section 5.1) on the subsequent request to the token endpoint to obtain the access token.

Root Cause Analysis

The vulnerability stems from improper scope validation in OAuth2 client flow processing. Key functions identified are:

DefaultOAuth2UserService.loadUser() - Directly processes user info and authority mapping from token response
OAuth2AuthorizationCodeAuthenticationProvider.authenticate() - Handles core authentication flow These functions in vulnerable versions lacked proper checks for empty scope responses, allowing attackers to bypass intended authorization constraints. The first function is higher confidence as it directly handles authority mapping from token data, while the second represents the authentication workflow entry point.
