CVE-2026-28304

Estado: AnalizadaCrítica (9.1)—

SolarWinds Serv-U is affected by a remote code execution vulnerability that, when exploited, can allow the arbitrary execution of code remotely as root. The impact is lower in Windows deployments.

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.

AV:N/PR:H requiere red y privilegios (T1210). RCE como root en Unix indica ejecución de código (T1059) y escalada/ejecución privilegiada (T1068).

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.
