Description

The SonicWall Secure Remote Access server (version 8.1.0.2-14sv) is vulnerable to a Remote Command Injection vulnerability in its web administrative interface. This vulnerability occurs in the &#39;extensionsettings&#39; CGI (/cgi-bin/extensionsettings) component responsible for handling some of the server&#39;s internal configurations. The CGI application doesn&#39;t properly escape the information it&#39;s passed when processing a particular multi-part form request involving scripts. The filename of the &#39;scriptname&#39; variable is read in unsanitized before a call to system() is performed - allowing for remote command injection. Exploitation of this vulnerability yields shell access to the remote machine under the nobody user account. This is SonicWall Issue ID 181195.
