CVE-2025-35451

PTZOptics and possibly other ValueHD-based pan-tilt-zoom cameras use hard-coded, default administrative credentials. The passwords can readily be cracked. Many cameras have SSH or telnet listening on all interfaces. The passwords cannot be changed by the user, nor can the SSH or telnet service be disabled by the user. It has a CVSS v3.1 base score of 9.8 (CRITICAL).

CVE-2025-35451 has a CVSS v3.1 score of 9.8 out of 10, rated CRITICAL. This is a critical vulnerability that should be patched immediately.
