CVE-2026-75969 is a critical vulnerability affecting PTZOptics cameras and their Firmware Upgrade Tool. It involves missing authentication in the firmware update mechanism, allowing unauthenticated users to install modified firmware without administrator credentials. This affects multiple PTZOptics camera models and versions prior to specified firmware releases. The vulnerability has a high CVSS score of 9.1, indicating severe risk.

PTZOptics and possibly other ValueHD-based pan-tilt-zoom cameras use default, shared credentials for the administrative web interface.

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.

PTZOptics PT30X-SDI/NDI-xx before firmware 6.3.40 is vulnerable to an OS command injection issue. The camera does not sufficiently validate the ntp_addr configuration value which may lead to arbitrary command execution when ntp_client is started. When chained with CVE-2024-8956, a remote and unauthenticated attacker can execute arbitrary OS commands on affected devices.

PTZOptics PT30X-SDI/NDI-xx before firmware 6.3.40 is vulnerable to an insufficient authentication issue. The camera does not properly enforce authentication to /cgi-bin/param.cgi when requests are sent without an HTTP Authorization header. The result is a remote and unauthenticated attacker can leak sensitive data such as usernames, password hashes, and configurations details. Additionally, the attacker can update individual configuration values or overwrite the whole file.
