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 t…

WebVPN on the Cisco Adaptive Security Appliances (ASA) device with software 8.0(4), 8.1.2, and 8.2.1 allows remote attackers to bypass certain protection mechanisms involving URL rewriting and HTML rewriting, and conduct cross-site scripting (XSS) attacks, by modifying the first hex-encoded character in a /+CSCO+ URI, aka Bug ID CSCsy80705.

Eval injection vulnerability in the csco_wrap_js function in /+CSCOL+/cte.js in WebVPN on the Cisco Adaptive Security Appliances (ASA) device with software 8.0(4), 8.1.2, and 8.2.1 allows remote attackers to bypass a DOM wrapper and conduct cross-site scripting (XSS) attacks by setting CSCO_WebVPN['process'] to the name of a crafted function, aka Bug ID CSCsy80694.

WebVPN on the Cisco Adaptive Security Appliances (ASA) device with software 8.0(4), 8.1.2, and 8.2.1 does not properly distinguish its own login screen from the login screens it produces for third-party (1) FTP and (2) CIFS servers, which makes it easier for remote attackers to trick a user into sending WebVPN credentials to an arbitrary server via a URL associated with that server, aka Bug ID CSCsy80709.

Unspecified vulnerability on Cisco Adaptive Security Appliances (ASA) 5500 Series devices 7.0 before 7.0(8)6, 7.1 before 7.1(2)82, 7.2 before 7.2(4)26, 8.0 before 8.0(4)24, and 8.1 before 8.1(2)14, when H.323 inspection is enabled, allows remote attackers to cause a denial of service (device reload) via a crafted H.323 packet.

Cisco Adaptive Security Appliances (ASA) 5500 Series and PIX Security Appliances 7.1(1) through 7.1(2)82, 7.2 before 7.2(4)27, 8.0 before 8.0(4)25, and 8.1 before 8.1(2)15, when AAA override-account-disable is entered in a general-attributes field, allow remote attackers to bypass authentication and establish a VPN session to an ASA device via unspecified vectors.

Memory leak on Cisco Adaptive Security Appliances (ASA) 5500 Series and PIX Security Appliances 7.0 before 7.0(8)6, 7.1 before 7.1(2)82, 7.2 before 7.2(4)30, 8.0 before 8.0(4)28, and 8.1 before 8.1(2)19 allows remote attackers to cause a denial of service (memory consumption or device reload) via a crafted TCP packet.

Unspecified vulnerability on Cisco Adaptive Security Appliances (ASA) 5500 Series and PIX Security Appliances 7.2 before 7.2(4)26, 8.0 before 8.0(4)22, and 8.1 before 8.1(2)12, when SQL*Net inspection is enabled, allows remote attackers to cause a denial of service (traceback and device reload) via a series of SQL*Net packets.

Cisco Adaptive Security Appliances (ASA) 5500 Series and PIX Security Appliances 7.0 before 7.0(8)1, 7.1 before 7.1(2)74, 7.2 before 7.2(4)9, and 8.0 before 8.0(4)5 do not properly implement the implicit deny statement, which might allow remote attackers to successfully send packets that bypass intended access restrictions, aka Bug ID CSCsq91277.

Unspecified vulnerability on Cisco Adaptive Security Appliances (ASA) 5500 Series devices 8.0 before 8.0(4)25 and 8.1 before 8.1(2)15, when an SSL VPN or ASDM access is configured, allows remote attackers to cause a denial of service (device reload) via a crafted (1) SSL or (2) HTTP packet.
