## Affected

- TP-Link Systems Inc. AX53 v1: fixed in 251029

## Description

A command injection vulnerability on AX53 v1 occurs in mscd debug functionality due to insufficient input handling, allowing log redirection to arbitrary files and concatenation of unvalidated file content into shell commands, enabling authenticated attackers to inject and execute arbitrary commands. Successful exploitation may allow execution of malicious commands and ultimately full control of the device.
