Technical details
The vulnerability exists within the 'ai_cmd' utility of the Acer Connect M6E 5G router. The utility runs with full root privileges and improperly handles communication by piping socket inputs directly into the popen() function without validation or authentication. This allows an unauthenticated attacker within adjacent network range to execute arbitrary shell commands as root. Acer has indicated that a resolution will involve replacing popen() with rigid allowlisted command parameterization, dropping root privileges, and implementing SELinux barriers.
