cjose: OpenIDC/cjose uses all-zero Content Encryption Key for AES-CBC-HMAC JWE encryption

A flaw was found in cjose. When encrypting a JSON Web Encryption JWE object using AES-CBC-HMAC algorithms, the library initializes the encryption key with all-zero bytes instead of generating a secure random key. As a result, an attacker who intercepts the encrypted message can decrypt sensitive...

kernel: ceph: kernel: Ceph: exploit of hardcoded IVECs, in a misuse of AES, resulting in authentication bypass

A flaw was found in the CephX authentication protocol used by Ceph, a distributed storage system. CephX uses AES-128-CBC encryption with a hardcoded initialization vector and no message authentication HMAC, making it vulnerable to the same class of unauthenticated-encryption attacks that...

ceph: ceph: RGW STS session tokens vulnerable to CBC bit-flip attack enabling admin privilege escalation

A flaw was found in Ceph RGW's STS Security Token Service session token implementation. The STS tokens use the same unauthenticated AES-128-CBC encryption as CephX, which lacks message authentication and uses a hardcoded initialization vector. Because there is no integrity protection on the token...
