Name of the Vulnerable Software and Affected Versions TCL LinkHub Mesh Wi-Fi AC1200 versions prior to the fixed version TCL LinkHub Mesh Wi-Fi MS1G 00 01.00 14

Description The issue is related to a buffer overflow vulnerability in the GetValue function of the LinkHub Mesh Wi-Fi microprogram, which occurs when processing the confcli file without checking the size of the input data. This vulnerability can be exploited by a remote attacker to execute arbitrary code. A specially-crafted configuration value can lead to a buffer overflow.

Recommendations For TCL LinkHub Mesh Wi-Fi AC1200, update to a version that fixes the buffer overflow vulnerability in the GetValue function. For TCL LinkHub Mesh Wi-Fi MS1G 00 01.00 14, modify configuration values to avoid triggering the buffer overflow vulnerability until a patch is available. As a temporary workaround, consider restricting access to the confcli binary to minimize the risk of exploitation.
