CVE-2024-14031

Estado: AnalizadaAlta (8.1)—

Sereal::Encoder versions from 4.000 through 4.009_002 for Perl embeds a vulnerable version of the Zstandard library.

Sereal::Encoder embeds a version of the Zstandard (zstd) library that is vulnerable to CVE-2019-11922. This is a race condition in the one-pass compression functions of Zstandard prior to version 1.3.8 could allow an attacker to write bytes out of bounds if an output buffer smaller than the recommended size was used.

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.

CVE-2024-14031 es una condición de carrera en zstd embebido en Sereal::Encoder que permite escribir fuera de límites (CWE-787); explotable remotamente sin autenticación (AV:N/PR:N), potenciando ejecución arbitraria 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.
