DESCRIPTION:
Two vulnerabilities have been discovered in WeBid, which can be
exploited by malicious people to conduct cross-site scripting attacks
and disclose sensitive information.

1) Input passed via the "id" parameter to confirm.php (when "lan" is
set) is not correctly 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.

2) Input passed via the "lan" parameter to active_auctions.php is not
properly verified before being used in e.g. includes/messages.inc.php.
This can be exploited to include arbitrary files from local resources
via directory traversal sequences and URL-encoded NULL bytes.

Successful exploitation requires that "magic_quotes_gpc" is
disabled.

The vulnerability is confirmed in version 0.85P1. Other versions may
also be affected.

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