CVE-2025-47290

Estado: AnalizadaAlta (7.6)—

containerd is a container runtime. A time-of-check to time-of-use (TOCTOU) vulnerability was found in containerd v2.1.0. While unpacking an image during an image pull, specially crafted container images could arbitrarily modify the host file system. The only affected version of containerd is 2.1.0. Other versions of containerd are not affected. This bug has been fixed in containerd 2.1.1. Users should update to this version to resolve the issue. As a workaround, ensure that only trusted images are used and that only trusted users have permissions to import images.

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.

TOCTOU en desempaquetado de imágenes con UI:A (interacción necesaria para pull). Impacto: modificación arbitraria del sistema de archivos host y potencial ejecución de código.

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.
