D-Link DNS-320/DNS-320LW/DNS-325/DNS-340L account_mgr.cgi cgi_user_add os command injection
D-Link · DNS-320
A command injection flaw in the cgi_user_add function of /cgi-bin/account_mgr.cgi in D-Link DNS-320, DNS-320LW, DNS-325 and DNS-340L network storage devices, where the name argument is not properly neutralised before being passed to the OS. An attacker with network access can remotely inject operating system commands through this argument without authentication or user interaction, though the attack is considered difficult to carry out.
A vulnerability was found in D-Link DNS-320, DNS-320LW, DNS-325 and DNS-340L up to 20241028. It has been declared as critical. Affected by this vulnerability is the function cgi_user_add of the file /cgi-bin/account_mgr.cgi?cmd=cgi_user_add. The manipulation of the argument name leads to os command injection. The attack can be launched remotely. The complexity of an attack is rather high. The exploitation appears to be difficult. The exploit has been disclosed to the public and may be used.
