An issue was discovered in Free5gc NRF 1.4.0. In the access-token generation logic of free5GC, the AccessTokenScopeCheck() function in file internal/sbi/processor/access_token.go bypasses all scope validation when the attacker uses a crafted targetNF value. This allows attackers to obtain an access token with any arbitrary scope.
AnalysisAI
Free5gc NRF 1.4.0 has an authorization bypass in access token generation that allows authenticated users to request tokens with broader scope than permitted.
Technical ContextAI
The AccessTokenScopeCheck function in Free5gc NRF (Network Repository Function) 1.4.0 has a CWE-863 incorrect authorization vulnerability that fails to properly validate token scope, allowing users to request overly permissive access tokens.
RemediationAI
Update Free5gc. Review issued access tokens for overly permissive scopes.
