An exploitable command injection vulnerability exists in the web server functionality of Moxa EDR-810 V4.1 build 17030317. A specially crafted HTTP POST can cause a privilege escalation, resulting in a root shell. An attacker can inject OS commands into the ip= parm in the "/goform/net_WebPingGetValue" URI to trigger this vulnerability.
Moxa NPort W2x50A products with firmware version 2.1 Build_17112017 or lower are vulnerable to several authenticated OS command injection vulnerabilities.
