Netwin SurgeFTP version 23c8 and prior contains a vulnerability in its web-based administrative console that allows authenticated users to execute arbitrary system commands via crafted POST requests to `surgeftpmgr.cgi`. This can lead to full remote code execution on the underlying system.
The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component.
