TITLE

SonicWall NetExtender NELaunchCtrl ActiveX control stack buffer overflow

DESCRIPTION

Stack-based buffer overflow in the SonicWall SSL-VPN NetExtender NELaunchCtrl ActiveX control before 2.1.0.51, and 2.5.x before 2.5.0.56, allows remote attackers to execute arbitrary code via a long string in the second argument to the AddRouteEntry method. SonicWALL SSL VPN Client is prone to multiple remote vulnerabilities. The issues occur in different ActiveX controls and include arbitrary-file-deletion and multiple stack-based buffer-overflow vulnerabilities. Attackers can exploit these issues to execute arbitrary code within the context of the affected application and delete arbitrary files on the client's computer. Failed exploit attempts will result in denial-of-service conditions. These issues affect SonicWALL SSL VPN 1.3.0.3 software as well as WebCacheCleaner 1.3.0.3 and NeLaunchCtrl 2.1.0.49 ActiveX controls; other versions may also be vulnerable. SonicWALL SSL-VPN can provide simple and easy-to-use VPN solutions for enterprise networks. Stack buffer, the following method can be used to jump the process to the UVWX domain: o.AddRouteEntry ("", "ABCDEFGHIJKLMNOPQRSTUVWX"); The following properties are also affected by Unicode overflow: serverAddress sessionId clientIPLower clientIPHigher userName domainName dnsSuffix. ---------------------------------------------------------------------- 2003: 2,700 advisories published 2004: 3,100 advisories published 2005: 4,600 advisories published 2006: 5,300 advisories published How do you know which Secunia advisories are important to you?
