Download of code without integrity check, inclusion of functionality from untrusted control sphere, and cleartext transmission of sensitive information vulnerability in Ozols Grupa OZOLS on Windows caused by an abandoned auto-update domain. Affected component: the automatic update channel - OzolsSQL client update path, the <db>_update SQL Server Agent job (@subsystem = N'ActiveScripting') and serv_update.vbs.

This issue affects OZOLS: before 1.1.1233.

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.

Vulnerabilidad en canal auto-actualización abandonado (CWE-494, CWE-319): descarga de código sin validación de integridad y transmisión en claro. Impacto: inyección de código malicioso vía cadena de suministro (actualización comprometida) y ejecución de comandos mediante ActiveScripting en SQL Agent

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.
