Descriptions

OpenVAS Administrator 1.2 before 1.2.2 and 1.3 before 1.3.2 allows remote attackers to bypass the OAP authentication restrictions and execute OAP commands via a crafted OAP request for version information, which causes the state to be set to CLIENT_AUTHENTIC.

OpenVAS Administrator 1.2 anterior a 1.2.2 y 1.3 anterior a 1.3.2 permite a atacantes remotos evadir las restricciones de autenticación OAP y ejecutar comandos OAP a través de una solicitud OAP manipulada para información de versión, lo que causa que el estado se configure como CLIENT_AUTHENTIC.

It has been identified that OpenVAS Manager and OpenVAS Administrator are vulnerable to authentication bypass due to an incorrect state assignment when processing OMP and OAP requests. It has been identified that this vulnerability may allow unauthorised access to OpenVAS Manager and OpenVAS Administrator on vulnerable systems.
