Introduction:
=============
Das Astaro Security Gateway 625 wurde speziell für den Schutz großer 
Unternehmen konzipiert. 
Basierend auf hochwertigen Intel-kompatiblen Serversystemen, einschließlich 
Dual IntelTM Xeon-Multi-Core-Prozessoren 
sowie redundanten Highspeed-Festplatten, bietet es selbst für die 
herausforderndsten Umgebungen optimale Performance 
und Zuverlässigkeit. Dieser Abschnitt beschreibt detailliert die verfügbaren 
Sicherheitsanwendungen, technischen 
Einzelheiten und Einsatzszenarien.

Severity:
=========
Medium


Details:
========
Multiple persistent Input Validation Vulnerabilities are detected on the 
Astaros Security Gateway application(appliance).
The vulnerability allows a local low privileged user account or remote attacker 
with medium required user inter action to manipulate 
module contexts on application-side.  Result of successful exploitation is 
session hijacking, phishing & stable context manipulation
or client side target exploitation out of the gateway web application context.

Proof of Concept:
=================
The vulnerabilities can be exploited by local attackers with restricted 
accounts or with medium user inter-action on the remote way.
For demonstration or reproduce ...


Code Review: Users - User Listing

<div style="display: inline; vertical-align: middle; white-space: nowrap; 
padding: 4px 2px 4px 0px;">>"<INCLUDE PERSISTENT SCRIPTCODE HERE!!!>
</div> <span>Known IP addresses of user '>"<INCLUDE PERSISTENT SCRIPTCODE 
HERE!!!>'</iframe></span>



Code Review: Add New Network Listing

<td style="font-weight: bold; padding-right: 4px; width: 
300px;"><span>>"<INCLUDE PERSISTENT SCRIPTCODE HERE!!!> 
(User Network)</iframe></span></td>



Code Review: Site to Site VPN - Certificate Listing

<span>WebAdmin certificate for >"<INCLUDE PERSISTENT SCRIPTCODE 
HERE!!!>.astaro.com</iframe></span>



Code Review: Extra RBL Zones - AntiSpam

<div style="overflow: hidden; font-size: 10px; margin: 0px; width: 212px; 
color: darkgreen;">>"<INCLUDE PERSISTENT SCRIPTCODE HERE!!!></frame>

Solution:
=========
Upgrade available since January 2012 (Sophos)


Risk:
=====
The security risk of the persistent input validation vulnerabilities are 
estimated as medium(+)/(-)high.
