openvpnserv.exe (aka the interactive service helper) in OpenVPN 2.4.x before 2.4.6 allows a local attacker to cause a double-free of memory by sending a malformed request to the interactive service. This could cause a denial-of-service through memory corruption or possibly have unspecified other impact including privilege escalation. openvpnserv.exe (también conocido como interactive service helper) en OpenVPN en versiones 2.4.x anteriores a la 2.4.6 permite que un atacante local provoque una doble liberación (double free) de memoria enviando una petición mal formada al servicio interactivo. Esto podría provocar una denegación de servicio (DoS) al corromper la memoria o, posiblemente, otro impacto no especificado, incluyendo el escalado de privilegios. • http://www.slackware.com/security/viewer.php?l=slackware-security&y=2018&m=slackware-security.568761 https://community.openvpn.net/openvpn/wiki/ChangesInOpenvpn24 https://github.com/OpenVPN/openvpn/commit/1394192b210cb3c6624a7419bcf3ff966742e79b https://github.com/OpenVPN/openvpn/releases/tag/v2.4.6 https://www.tenable.com/security/research/tra-2018-09 • CWE-415: Double Free •

A cross-protocol scripting issue was discovered in the management interface in OpenVPN through 2.4.5. When this interface is enabled over TCP without a password, and when no other clients are connected to this interface, attackers can execute arbitrary management commands, obtain sensitive information, or cause a denial of service (SIGTERM) by triggering XMLHttpRequest actions in a web browser. This is demonstrated by a multipart/form-data POST to http://localhost:23000 with a "signal SIGTERM" command in a TEXTAREA element. NOTE: The vendor disputes that this is a vulnerability. They state that this is the result of improper configuration of the OpenVPN instance rather than an intrinsic vulnerability, and now more explicitly warn against such configurations in both the management-interface documentation, and with a runtime warning ** EN DISPUTA ** Se ha descubierto un problema en la interfaz de gestión en OpenVPN hasta la versión 2.4.5. • http://blog.0xlabs.com/2018/03/openvpn-remote-information-disclosure.html • CWE-134: Use of Externally-Controlled Format String •
