CVE-2025-35451 | Pan-Tilt-Zoom cameras hard-coded default passwords with SSH and telnet enabled

Exp

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.

9.8 3.1 CRITICAL
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H Click to expand
Attack vector (AV:N)
Could be attacked over the internet or any normal routed network—not just someone sitting at the machine.
Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:N)
No account or special rights needed—anonymous or random user is enough.
User interaction (UI:N)
Nobody has to click “OK” or open a trap file; it can work without a victim helping.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:H)
Serious risk that confidential data gets exposed in a big way.
Integrity (I:H)
They could widely tamper with or forge data—trust in the data is badly hurt.
Availability (A:H)
Could take the service down hard or make it unusable for people who depend on it.
