CVE-2022-36635Public exploitNetwork attack vector

Authenticated command execution via SQL injection

Published Oct 7, 2022 · Updated Jul 9, 2026

SQL injection in ZKTeco ZKBioSecurity V5000 4.1.3 allows remote authenticated users to execute operating-system commands. The baseOpLog.do handler concatenates opTimeBegin and opTimeEnd into a PostgreSQL query, while block comments bypass its sanitization filter. A valid session cookie is required; injected stacked queries can invoke PostgreSQL COPY FROM PROGRAM for command execution.
