Estado: AnalizadaAlta (7.5)—

An issue has been discovered in GitLab CE/EE affecting all versions from 8.7 before 17.10.8, 17.11 before 17.11.4, and 18.0 before 18.0.2. Improper input validation in Tokens Names could be used to trigger a denial of service.

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 AV:N/AC:L/PR:N/UI:N indica exploitación remota sin requerimientos. CWE-770 (Allocation of Resources Without Limits) y descripción de DoS por validación impropia de nombres de tokens apunta a T1499.004 (exhaustión de recursos de aplicación).

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.
