CVE-2026-53479
Dell PowerProtect Data Domain, versions 7.7.1.0 through 8.7, LTS2026 release version 8.6.1.0 through 8.6.1.10, LTS2025 release version 8.3.1.0 through 8.3.1.30, LTS2024 release versions 7.13.1.0 through 7.13.1.70 contain an improper neutralization of special elements used in an OS command ('OS command Injection') vulnerability. A remote high privileged attacker could potentially exploit this vulnerability, leading to protection mechanism bypass. This is a Critical vulnerability as it allows an attacker to invoke arbitrary command execution with root privileges; so Dell recommends customers to upgrade at the earliest opportunity.
CVSS
- Versión: 3.1
- Vector: CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H
- Puntuación base: 7.2
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días: 1.97%
- Percentil entre todas las CVEs puntuadas: 80
- 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 movement95 % - Impacto principal
T1059Command and Scripting Interpreterexecution95 % - Impacto secundario
T1068Exploitation for Privilege Escalationprivilege escalation90 %
OS command injection (CWE-78) en servicio remoto con PR:H permite ejecución de comandos arbitrarios como root. Vector CVSS AV:N/PR:H/AC:L dicta T1210 (explotación de servicios remotos con privilegios). Impacto: ejecución de comandos (T1059) y escalada local (T1068) confirmada por "root privileges".
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.
