API permission bypass via logic bug

Published Oct 30, 2026 · Updated Oct 30, 2026 · Assigned by tlt_net

Description

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.
