Sending a non-base64 'basic' auth with special characters can cause APICast to incorrectly authenticate a request. A malformed basic authentication header containing special characters bypasses authentication and allows unauthorized access to the backend. This issue can occur due to a failure in the base64 decoding process, which causes APICast to skip the rest of the authentication checks and proceed with routing the request upstream.\n\n## Affected\n\n- `gateway <= 2.14.2`\n- `3scale-amp2/apicast-gateway-rhel8 (all versions)`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"twilight","depthScore":41,"depthScoreParts":{"impact":41.3,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
