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 ...
