From 197d99272a599fd5ad81f1d21a88055796a32529 Mon Sep 17 00:00:00 2001 From: Kai Blin Date: Thu, 7 Jul 2011 10:03:33 +0200 Subject: [PATCH 01/13] 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.
