Subject: [PATCH] s3 swat: Fix possible XSS attack (bug #8289)
Nobuhiro Tsuji of NTT DATA SECURITY CORPORATION reported a possible XSS attack
against SWAT, the Samba Web Administration Tool. The attack uses reflection to
insert arbitrary content into the "change password" page.
This patch fixes the reflection issue by not printing user-specified content on
the website anymore.

From: Kai Blin <kai@samba.org>
Date: Tue, 12 Jul 2011 08:08:24 +0200
Subject: [PATCH 12/12] s3 swat: Create random nonce in CGI mode
In CGI mode, we don't get access to the user's password, which would
reduce the hash used so far to parameters an attacker can easily guess.
To work around this, read the nonce from secrets.tdb or generate one if
it's not there.
Also populate the C_user field so we can use that for token creation.
Signed-off-by: Kai Blin <kai@samba.org>
The last 12 patches address bug #8290 (CSRF vulnerability in SWAT).
This addresses CVE-2011-2522 (Cross-Site Request Forgery in SWAT).
