TP-Link ARCHER AX21

TP-Link AX1800 hotplugd Firewall Rule Race Condition Vulnerability

TP-Link Archer AX21(US)_V3_1.1.4 Build 20230219 and AX21(US)_V3.6_1.1.4 Build 20230219 are vulnerable to Buffer Overflow.

TP-Link Archer AX21 (AX1800) firmware versions before 1.1.4 Build 20230219 contained a command injection vulnerability in the country form of the /cgi-bin/luci;stok=/locale endpoint on the web management interface. Specifically, the country parameter of the write operation was not sanitized before being used in a call to popen(), allowing an unauthenticated attacker to inject commands, which would be run as root, with a simple POST request.
