Описание
Уязвимость реализации стандарта Security Assertion Markup Language (SAML) механизма аутентификации Single sign-on (SSO) микропрограммного обеспечения межсетевых экранов Cisco Adaptive Security Appliance (ASA) и Cisco Firepower Threat Defense (FTD) связана с недостатками разграничения доступа в результате некорректной проверки URL-адреса для входа. Эксплуатация уязвимости может позволить нарушителю, действующему удаленно, обойти процедуру аутентификации и подключиться к защищенным сетям, путем установки VPN-сеанса с уязвимым устройством после проверки подлинности другого VPN-пользователя на уязвимом устройстве с помощью единого входа SAML

A vulnerability in the implementation of Security Assertion Markup Language (SAML) 2.0 single sign-on (SSO) for remote access VPN in Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to intercept the SAML assertion of a user who is authenticating to a remote access VPN session. This vulnerability is due to insufficient validation of the login URL. An attacker could exploit this vulnerability by persuading a user to access a site that is under the control of the attacker, allowing the attacker to modify the login URL. A successful exploit could allow the attacker to intercept a successful SAML assertion and use that assertion to establish a remote access VPN session toward the affected device with the identity and permissions of the hijacked user, resulting in access to the protected network.
