Vulnerability from variot
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. (DoS) It may be in a state. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of TP-Link Archer AX21 routers. Authentication is not required to exploit this vulnerability.The specific flaw exists within the merge_country_config function. The issue results from the lack of proper validation of a user-supplied string before using it to execute a system call. An attacker can leverage this vulnerability to execute arbitrary code in the context of root. TP-Link Archer AX21 AX1800 is a TP-Link WIFI6 router.
There is a command injection vulnerability in TP-Link Archer AX21 AX1800. The vulnerability comes from not filtering user input
