An os command injection vulnerability exists in the touchlist_sync.cgi touchlistsync() functionality of Wavlink AC3000 M33A8.V5030.210505. A specially crafted set of HTTP requests can lead to arbitrary code execution. An attacker can send an HTTP request to trigger this vulnerability.
The product constructs all or part of a command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended command when it is sent to a downstream component.
