Certain Secure Access SA Series SSL VPN products (originally developed by Juniper Networks but now sold and supported by Pulse Secure, LLC) allow privilege escalation, as demonstrated by Secure Access SSL VPN SA-4000 5.1R5 (build 9627) 4.2 Release (build 7631). This occurs because appropriate controls are not performed. Specifically, it is possible for a readonly user to change the administrator user password by making a local copy of the /dana-admin/user/update.cgi page, changing the "user" value, and saving the changes.

Improper restriction of communication channel to intended endpoints vulnerability in HTTP daemon in Synology SSL VPN Client before 1.2.4-0224 allows remote attackers to conduct man-in-the-middle attacks via a crafted payload.

FortiClient before 4.3.5.472 on Windows, before 4.0.3.134 on Mac OS X, and before 4.0 on Android; FortiClient Lite before 4.3.4.461 on Windows; FortiClient Lite 2.0 through 2.0.0223 on Android; and FortiClient SSL VPN before 4.0.2258 on Linux proceed with an SSL session after determining that the server's X.509 certificate is invalid, which allows man-in-the-middle attackers to obtain sensitive information by leveraging a password transmission that occurs before the user warning about the certificate problem.

Race condition in the CIFS implementation in the rewriter module in the Clientless SSL VPN component on Cisco Adaptive Security Appliances (ASA) devices allows remote authenticated users to cause a denial of service (device reload) by accessing resources within multiple sessions, aka Bug ID CSCub58996.

Multiple cross-site scripting (XSS) vulnerabilities in Barracuda SSL VPN before 2.2.2.203 (2012-07-05) allow remote attackers to inject arbitrary web script or HTML via the (1) policyLaunching, (2) resourcePrefix, or (3) actionPath parameter in showUserResourceCategories.do; (4) list or (5) path parameter to fileSystem.do; or (6) return-To parameter to launchAgent.do.

Cross-site scripting (XSS) vulnerability in global-protect/login.esp in Palo Alto Networks Global Protect Portal, Global Protect Gateway, and SSL VPN portals 3.1.x through 3.1.11 and 4.0.x through 4.0.5 allows remote attackers to inject arbitrary web script or HTML via the inputStr parameter in a Login action.

Stack-based buffer overflow in SonicWALL SSL-VPN End-Point Interrogator/Installer ActiveX control (Aventail.EPInstaller) before 10.5.2 and 10.0.5 hotfix 3 allows remote attackers to execute arbitrary code via long (1) CabURL and (2) Location arguments to the Install3rdPartyComponent method.

The Cisco trial client on Linux for Cisco AnyConnect SSL VPN allows local users to overwrite arbitrary files via a symlink attack on unspecified temporary files.

Cross-site scripting (XSS) vulnerability in wa/auth in PortWise SSL VPN 4.6 allows remote attackers to inject arbitrary web script or HTML via the reloadFrame parameter.

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…
