CVE-2023-1082Network attack vector

Authenticated root command execution via OS command injection

Published Apr 9, 2024 · Updated Aug 21, 2024

OS command injection in Welotec TK500v1 router firmware before 2.3.0.r5542 allows remote authenticated users to gain root access. The public CNA and vendor advisory do not identify the affected endpoint, parameter, or command-building operation, so the precise input-handling failure is undisclosed. A low-privileged router account and network access to a management service are required; successful exploitation executes commands with root authority and permits device manipulation.
