CVE-2026-22306Network attack vector

RCE via abandoned unsigned update domain

Published Aug 19, 2026 · Updated Aug 19, 2026

Remote code execution in Ozols Grupa OZOLS before 1.1.1233 allows remote attackers to run code via the abandoned auto-update domain. The OzolsSQL update path, the _update SQL Server Agent ActiveScripting job, and serv_update.vbs fetch Vers.txt, archives, and even arj.exe over cleartext HTTP from its2.lv, then trust only a version number before invoking the downloaded content with WScript.Shell.Run or xp_cmdshell. No foothold or user action is required beyond control of the lapsed domain; code reaches the database server as the SQL Server service account and then propagates through the sprg table to attached workstations.
