Name of the Vulnerable Software and Affected Versions WAVLINK WN536AX6-A version V260507

Description A stack-based buffer overflow exists in the OpenVPN Handler component within the /protocol.csp file. The issue occurs when the strcpy() function processes the openvpn ip argument, allowing a remote attacker to trigger the overflow.

Recommendations As a temporary workaround, restrict access to the OpenVPN Handler component to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
