Name of the Vulnerable Software and Affected Versions Totolink CA750-PoE version 6.2c.510

Description An OS command injection issue exists in the Setting Handler component. The setNetworkDiag() function within the '/cgi-bin/cstecgi.cgi' endpoint fails to properly sanitize several arguments, allowing a remote attacker to execute arbitrary operating system commands. The affected variables include NetDiagHost, NetDiagPingNum, NetDiagPingSize, NetDiagPingTimeOut, and NetDiagTracertHop.

Recommendations As a temporary workaround, restrict access to the '/cgi-bin/cstecgi.cgi' endpoint or disable the setNetworkDiag() function until a fix is available. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
