CVE-2025-36529Network attack vector

Authenticated command execution via undisclosed input handling

Published Jun 27, 2025 · Updated Jun 30, 2025

OS command injection in TB-eye network and AHD recorders allows remote authenticated users to execute arbitrary OS commands. TB-eye and JPCERT/CC have not published the affected request parameter, handler, or operation that fails to neutralize shell metacharacters. Device login with high privileges is required, after which injected commands can read or alter data or stop recorder functions.
