DESCRIPTION:
rgod has discovered a vulnerability in WebSVN, which can be exploited
by malicious people to compromise a vulnerable system.

Input passed via the "path" parameter to dl.php is not properly
sanitised in include/command.php before being used as a command line
argument and can be exploited to inject arbitrary shell commands.

Successful exploitation requires the "$config->allowDownload()"
option to be enabled in include/config.php (disabled by default).

The vulnerability is confirmed in version 2.3.2 running on Windows.
Other versions may also be affected.

SOLUTION:
Edit the source code to ensure that input is properly sanitised.
