CVE-2020-25747

The Telnet service of Rubetek RV-3406, RV-3409, and RV-3411 cameras (firmware versions v342, v339) can allow a remote attacker to gain access to RTSP and ONFIV services without authentication. Thus, the attacker can watch live streams from the camera, rotate the camera, change some settings (brightness, clarity, time), restart the camera, or reset it to factory settings.

9.4 3.1 CRITICAL
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:L/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.

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:L)
Attackers could change some data, but it’s limited—not everything goes.
