CVE-2025-1991

Estado: AnalizadaAlta (7.5)—

IBM Informix Dynamic Server 12.10,14.10, and15.0 could allow a remote attacker to cause a denial of service due to an integer underflow when processing packets.

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/PR:N/UI:N indica explotación remota sin privilegios (T1190). Integer underflow al procesar paquetes causa DoS de aplicación (T1499.004).

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.
