CVE-2009-2631

https://notcve.org/view.php?id=CVE-2009-2631

Multiple clientless SSL VPN products that run in web browsers, including Stonesoft StoneGate; Cisco ASA; SonicWALL E-Class SSL VPN and SonicWALL SSL VPN; SafeNet SecureWire Access Gateway; Juniper Networks Secure Access; Nortel CallPilot; Citrix Access Gateway; and other products, when running in configurations that do not restrict access to the same domain as the VPN, retrieve the content of remote URLs from one domain and rewrite them so they originate from the VPN's domain, which violates the same origin policy and allows remote attackers to conduct cross-site scripting attacks, read cookies that originated from other domains, access the Web VPN session to gain access to internal resources, perform key logging, and conduct other attacks. NOTE: it could be argued that this is a fundamental design problem in any clientless VPN solution, as opposed to a commonly-introduced error that can be fixed in separate implementations. Therefore a single CVE has been assigned for all products that have this design. Múltiples productos VPN de SSL sin cliente que se ejecutan en navegadores web, incluyendo StoneGate de Stonesoft; ASA de Cisco; E-Class SSL VPN de SonicWALL y SSL VPN de SonicWALL; SecureWire Access Gateway de SafeNet; Networks Secure Access de Juniper; CallPilot de Nortel; Access Gateway de Citrix; y otros productos, cuando se ejecutan en configuraciones que no restringen el acceso al mismo dominio que la VPN, recuperan el contenido de las direcciones URL remotas de un dominio y las reescriben para que se originen desde el dominio de la VPN, lo que viola la política del mismo origen y permite a atacantes remotos conducir ataques de tipo cross-site scripting, leer cookies que se originaron desde otros dominios, acceder a la sesión de VPN web para conseguir acceso a los recursos internos, realizar el registro de claves y conducir otros ataques. NOTA: se podría argumentar que se trata de un problema de diseño fundamental en cualquier solución VPN sin cliente, a diferencia de un error comúnmente introducido que puede ser corregido en implementaciones separadas. • http://kb.juniper.net/KB15799 http://seclists.org/fulldisclosure/2006/Jun/238 http://seclists.org/fulldisclosure/2006/Jun/269 http://seclists.org/fulldisclosure/2006/Jun/270 http://secunia.com/advisories/37696 http://secunia.com/advisories/37786 http://secunia.com/advisories/37788 http://secunia.com/advisories/37789 http://securitytracker.com/id?1023255 http://support.nortel.com/go/main.jsp?cscat=BLTNDETAIL&DocumentOID=984744 http://www.kb.cert.org/vuls/id/261869 http:/ • CWE-264: Permissions, Privileges, and Access Controls •
