CVE-2024-49400

Estado: AplazadaCrítica (9.8)—

Tacquito prior to commit 07b49d1358e6ec0b5aa482fcd284f509191119e2 was not properly performing regex matches on authorized commands and arguments. Configured allowed commands/arguments were intended to require a match on the entire string, but instead only enforced a match on a sub-string. That would have potentially allowed unauthorized commands to be executed.

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.

Vulnerabilidad en validación de comandos autorizados permite ejecución no autorizada de comandos remotos en Tacquito (AV:N/PR:N/UI:N). Fallo de regex en substring vs fullmatch expone a ejecución arbitraria.

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.
