Estado: AplazadaAlta (8.2)—

A flaw was found in the Mirror Registry. The quay-app container shipped as part of the Mirror Registry for OpenShift has write access to the `/etc/passwd`. This flaw allows a malicious actor with access to the container to modify the passwd file and elevate their privileges to the root user within that pod.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).
