Introduction:

Das Astaro Security Gateway 625 wurde speziell fur den Schutz gro?er Unternehmen konzipiert.
Basierend auf hochwertigen Intel-kompatiblen Serversystemen, einschlie?lich Dual IntelTM Xeon-Multi-Core-Prozessoren
sowie redundanten Highspeed-Festplatten, bietet es selbst fur die herausforderndsten Umgebungen optimale Performance
und Zuverlassigkeit. Dieser Abschnitt beschreibt detailliert die verfugbaren Sicherheitsanwendungen, technischen
Einzelheiten und Einsatzszenarien.

Status:

Published

Affected Products:

Exploitation-Technique:

Remote

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>
</div><td><img src="core/img/icons/trash.png" stlye="margin:0px 2px 0px 0px;cursor:pointer;" class="

Solution:

Upgrade available since January 2012 (Sophos)

Risk:

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