CVE-2025-24965

Estado: AplazadaAlta (8.5)—

crun is an open source OCI Container Runtime fully written in C. In affected versions A malicious container image could trick the krun handler into escaping the root filesystem, allowing file creation or modification on the host. No special permissions are needed, only the ability for the current user to write to the target file. The problem is fixed in crun 1.20 and all users are advised to upgrade. There are no known workarounds for this vulnerability.

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).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

Vector CVSS con UI:P (interacción del usuario) en contexto de imagen de contenedor maliciosa sugiere T1203. Impacto primario es modificación de ficheros en el host (T1565.001); secundario, lectura de datos (T1005).

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.
