Description
The vulnerability allows a remote attacker to execute arbitrary shell commands on the target system.
The vulnerability exists due to improper input validation in the "iw_webs" functionality. A specially crafted "iw_serverip" parameter can cause user input to be reflected in a subsequent "iw_system" call. A remote authenticated attacker can send specially crafted commands and execute arbitrary OS commands on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
