CVE-2025-29625

Estado: AnalizadaAlta (7.8)—

A buffer overflow vulnerability in Astrolog v7.70 allows attackers to execute arbitrary code or cause a Denial of Service (DoS) via an overly long environment variable passed to FileOpen function.

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.

Buffer overflow local (AV:L, PR:L) sin interacción del usuario permite escalada de privilegios y ejecución arbitraria de código. DoS es posible por el overflow.

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.
