Description:
Some vulnerabilities have been reported in SonicWALL SSL VPN, which can be exploited by malicious people to delete arbitrary files or to compromise a user's system.
1) Boundary errors within the NetExtender NELaunchCtrl ActiveX control when handling arguments passed to certain methods (e.g. "AddRouteEntry()", "serverAddress()", "sessionId()", "clientIPLower()", "clientIPHigher()", "userName()", "domainName()", and "dnsSuffix()") can be exploited to cause buffer overflows when a user e.g. visits a malicious website.
2) The WebCacheCleaner ActiveX control includes the insecure method "FileDelete()", which can be exploited to delete arbitrary files.
The vulnerabilities are reported in WebCacheCleaner ActiveX control version 1.3.0.3 and NeLaunchCtrl ActiveX control version 2.1.0.49. Other versions may also be affected.
Solution:
Update to firmware version 2.5 for SonicWALL SSL VPN 2000/4000, and version 2.1 for SonicWALL SSL-VPN 200.
