## Technical details

This is an OS command injection vulnerability in the /cgi-bin/iscsi_mgr.cgi script on D-Link DNS-340L and DNS-345 NAS devices. The vulnerability exists in the handling of parameters such as alias, username, password, and volume_location, which are passed unsanitized to shell commands. An attacker can craft malicious input containing shell metacharacters to execute arbitrary commands with the privileges of the web server process. The attack is remotely exploitable over the network and does not require authentication. A public proof-of-concept has been released, increasing the risk of widespread exploitation.
