CVE-2022-43755
Rancher: Non-random authentication token
In short
Rancher generates authentication tokens with insufficient randomness, allowing attackers who know an old token to predict or reuse it even after renewal. This undermines the security of token-based authentication.
Technical detail
CWE-331 (Insufficient Entropy) in Rancher's cattle-token generation enables attackers with knowledge of a previous token to infer or continue exploiting subsequent tokens due to weak randomization. The vulnerability affects token renewal mechanisms, allowing persistence of unauthorized access despite token rotation. Affected versions: Rancher <2.6.10 and <2.7.1.
Summary generated and translated by AI from the official description.
A Insufficient Entropy vulnerability in SUSE Rancher allows attackers that gained knowledge of the cattle-token to continue abusing this even after the token was renewed. This issue affects: SUSE Rancher Rancher versions prior to 2.6.10; Rancher versions prior to 2.7.1.
