CVE-2020-25688

CVE-2020-25688 is a low-severity vulnerability in Redhat Advanced Cluster Management For Kubernetes with a CVSS 3.x base score of 3.5. It is not currently listed as actively exploited by CISA, and its EPSS exploit-prediction score is low. The underlying weakness is classified as CWE-798.

Key facts

Description

A flaw was found in rhacm versions before 2.0.5 and before 2.1.0. Two internal service APIs were incorrectly provisioned using a test certificate from the source repository. This would result in all installations using the same certificates. If an attacker could observe network traffic internal to a cluster, they could use the private key to decode API requests that should be protected by TLS sessions, potentially obtaining information they would not otherwise be able to. These certificates are not used for service authentication, so no opportunity for impersonation or active MITM attacks were made possible.
