CVE-2026-30896

Estado: AnalizadaAlta (8.4)—

The installer for Qsee Client versions 1.0.1 and prior insecurely load Dynamic Link Libraries (DLLs). When a user is directed to place some malicious DLL to the same directory and execute the affected installer, then arbitrary code may be executed with the administrative privilege.

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:L + UI:A indica ejecución en cliente (abrir instalador); DLL hijacking (CWE-427) permite escalada a admin. El instalador carga DLLs de forma insegura desde el directorio 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.
