CVE-2026-82104
CriticalCVSS 9.4Summary
In Teltonika Networks RUTOS devices (versions 7.22 through 7.24.2) and TSWOS devices (versions 1.9 through 1.10), an unauthenticated user can directly call LUA functions, bypassing validations that would normally apply to API requests. Because these requests do not follow proper flows, this can lead to OS command execution.
Risk Assessment
An unauthenticated attacker could remotely execute operating system commands on the network device, potentially taking full control of the router or switch and pivoting further into the organization's network.
Recommendation
Upgrade RUTOS/TSWOS to a version later than 7.24.2 (RUTOS) or 1.10 (TSWOS) per the vendor's guidance, and restrict access to device management interfaces.

See all- CVE-2026-75826High
Command injection in the backup function in Teltonika Networks RUTOS 7.22 before 7.24.6 and 7.25 before 7.25.2 (RUT, RUTX, RUTM, RUTC, ATRM, CAP, OXA, DAP, TRB, OTD, and EBG devices), RUTOS 7.22 before 7.25.2 (TAP devices), and TSWOS 1.9 before 1.10.4 (TSW and SWM devices) allows a remote authenticated attacker to execute arbitrary OS commands.
- CVE-2026-16455Medium
In Teltonika Networks RUTOS devices running versions 7.07.1 through 7.24.1 and TSWOS devices running versions 1.03 through 1.10, a vulnerability exists whereby a lower privileged user can escalate privileges to administrative level due to unsafe calls to an execl function.
Original NVD description (English source)
In Teltonika Networks RUTOS devices running versions from 7.22 through 7.24.2 and TSWOS devices running versions 1.9 through 1.10, a vulnerability exists whereby an unauthenticated user can directly call LUA functions, bypassing validations that might be called under normal API requests. Due to those requests not following proper flows, this could lead to OS command execution. This issue affects RUT: from 7.22 through 7.24.2; RUTX: from 7.22 through 7.24.2; RUTM: from 7.22 through 7.24.2; RUTC: from 7.22 through 7.24.2; ATRM: from 7.22 through 7.24.2; TAP: from 7.22 through 7.24.2; CAP: from 7.22 through 7.24.2; OXA: from 7.22 through 7.24.2; DAP: from 7.22 through 7.24.2; TRB: from 7.22 through 7.24.2; OTD: from 7.22 through 7.24.2; EBG: from 7.22 through 7.24.2; SWM: from 1.9 through 1.10; TSW: from 1.9 through 1.10.
