CVE-2026-59686
An OS Command Injection vulnerability in Progress Software LoadMaster, ECS Connection Manager, Object Scale Connection Manager, and MOVEit WAF allows an authenticated attacker with high privileges to execute arbitrary operating system commands on the affected appliance via the management interface, potentially resulting in complete system compromise.
CVSS
- Versión: 3.1
- Vector: CVSS:3.1/AV:A/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H
- Puntuación base: 8.4
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días: 1.68%
- Percentil entre todas las CVEs puntuadas: 76
- Fecha de la puntuación: 5/10/2026
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
T1210Exploitation of Remote Serviceslateral movement85 % - Impacto principal
T1059Command and Scripting Interpreterexecution90 % - Impacto secundario
T1068Exploitation for Privilege Escalationprivilege escalation75 %
CWE-78 (inyección de comandos OS) en interfaz de gestión remota con PR:H requiere acceso autenticado a servicios remotos (T1210). El atacante logra ejecución de comandos arbitrarios (T1059) y potencial escalada a root/admin (T1068) tras el compromiso inicial.
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.
