CVE-2023-4853

Quarkus: http security policy bypass

publishedCWE-148

A flaw was found in Quarkus where HTTP security policies are not sanitizing certain character permutations correctly when accepting requests, resulting in incorrect evaluation of permissions. This issue could allow an attacker to bypass the security policy altogether, resulting in unauthorized endpoint access and possibly a denial of service.

Fixes and workarounds

Workaround

Use a ‘deny’ wildcard for base paths, then authenticate specifics within that: Examples: ``` deny: /* authenticated: /services/* ``` or ``` deny: /services/* roles-allowed: /services/rbac/* ``` NOTE: Products are only vulnerable if they use (or allow use of) path-based HTTP policy configuration. Products may also be affected–shipping the component in question–without being vulnerable (“affected at reduced impact”). See https://access.redhat.com/security/vulnerabilities/RHSB-2023-002 for more detailed mitigations.
