DESCRIPTION:
Amine ABOUD has discovered a vulnerability and a weakness in
Blank'N'Berg, which can be exploited by malicious people to disclose
system information and conduct cross-site scripting attacks.

1) Input passed to the "_path" parameter in index.php is not properly
sanitised before being used to list directories and files. This can be
exploited to disclose the contents of arbitrary directories via
directory traversal attacks.

2) Input passed to the "_path" parameter in index.php is not properly
sanitised before being returned to the user. This can be exploited to
execute arbitrary HTML and script code in a user's browser session in
context of an affected site.

The vulnerability and the weakness have been confirmed in version
0.20060215. Other versions may also be affected.

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