CyberRota Analysis

AI-Generated

An authentication bypass vulnerability in Portainer CE versions prior to 2.44.0 allows low-privileged authenticated users to circumvent Docker proxy authorization checks due to non-canonical URL normalization issues. This flaw enables attackers to manipulate request paths, potentially gaining root-level access to the underlying Docker host. Organizations using affected versions of Docker should prioritize immediate remediation to mitigate the risk of unauthorized access and potential system compromise.

Original NVD Description

An authentication bypass vulnerability in Portainer CE through 2.44.0 allows authenticated low-privileged users to bypass Docker proxy authorization checks via non-canonical URL normalization, defeating all authorization middleware. The proxy endpoint fails to normalize request paths before applying access controls, allowing crafted requests to be interpreted differently by the proxy and the authorization layer. Successful exploitation grants the attacker root-level access to the underlying Docker host.
