Descriptions

A vulnerability in the Ceph Rados Gateway (RadosGW) OIDC provider allows attackers to bypass JWT signature verification by supplying a token with "none" as the algorithm (alg). This occurs because the implementation fails to enforce strict signature validation, enabling attackers to forge valid tokens without a signature.

ceph: rhceph-container: Authentication bypass in CEPH RadosGW

It was discovered that Ceph incorrectly handled unsupported JWT algorithms in the RadosGW gateway. An attacker could possibly use this issue to bypass certain authentication checks and restrictions.
