OpenVPN Access Server older than version 2.8.4 and version 2.9.5 generates new user authentication tokens instead of reusing exiting tokens on reconnect making it possible to circumvent the initial token expiry timestamp. El servidor de acceso OpenVPN anterior a la versión 2.8.4 y la versión 2.9.5 genera nuevos tokens de autenticación de usuario en lugar de reutilizar los tokens existentes en la reconexión, lo que permite eludir la marca de tiempo de caducidad del token inicial • https://openvpn.net/vpn-server-resources/release-notes • CWE-302: Authentication Bypass by Assumed-Immutable Data CWE-613: Insufficient Session Expiration •

An issue was discovered in OpenVPN Access Server before 2.7.0 and 2.8.x before 2.8.3. With the full featured RPC2 interface enabled, it is possible to achieve a temporary DoS state of the management interface when sending an XML Entity Expansion (XEE) payload to the XMLRPC based RPC2 interface. The duration of the DoS state depends on available memory and CPU speed. The default restricted mode of the RPC2 interface is NOT vulnerable. Se ha descubierto un problema en OpenVPN Access Server versiones anteriores a la versión 2.7.0 y versiones 2.8.x anteriores a la versión 2.8.3. • https://openvpn.net/vpn-server-resources/release-notes/#Release_notes_for_OpenVPN_Access_Server_283 • CWE-776: Improper Restriction of Recursive Entity References in DTDs ('XML Entity Expansion') •
