CVE-2025-52584
In Ashlar-Vellum Cobalt, Xenon, Argon, Lithium, and Cobalt Share versions prior to 12.6.1204.204, the affected applications lack proper validation of user-supplied data when parsing XE files. This could lead to a heap-based buffer overflow. An attacker could leverage this vulnerability to execute arbitrary code in the context of the current process.
CVSS
- Versión: 4.0

- Puntuación base: 8.4
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días: 0.17%
- Percentil entre todas las CVEs puntuadas: 5
- Fecha de la puntuación: 6/10/2026
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.
- Explotación
T1203Exploitation for Client Executionexecution85 % - Impacto principal
T1059Command and Scripting Interpreterexecution80 %
Vector CVSS local (AV:L) con interacción del usuario (UI:A) indica ejecución en cliente al abrir archivo XE preparado. Heap overflow permite ejecutar código arbitrario en el proceso actual.
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.
