Barracuda Networks Spam Firewall Cross-Site Scripting Vulnerability CVE Number: CVE-2008-2333
Vulnerability Type / Importance: Cross-Site Scripting (Reflected) / Medium
Problem Discovered 24 April 2008 Vendor Contacted 24 April 2008 Advisory Published 22 May 2008
Abstract The Barracuda Spam Firewall device web administration interface is vulnerable to a reflected cross-site scripting vulnerability which may allow theft of administrative credentials or downloading of malicious content.
The Barracuda device presents LDAP testing functionality via a script called 'ldap_test.cgi'. The script does not sufficiently validate user-supplied input within the 'email' parameter. As a result, client-supplied script code can be injected into the 'email' parameter that would execute in the browser within the security context of the Barracuda device. Vendor information: http://www.barracudanetworks.com/ns/support/tech_alert.php
Proof of Concept:
https://<vulnerable_host>/cgi-bin/ldap_test.cgi?host=127.0.0.1&port=1&tl s_mode=tls_mode&tls_require=&username=&password=&filter=&searchbase=&uni que_attr=&email_attr=&domain=*&email=%3Cscript%3Ealert(document.cookie)% 3C/script%3E
Access to the web management application can be limited by IP address. Firmware release 3.5.11.025 has been released by the vendor to address this issue; however the patch has not been tested by IRM.
IRM confirmed the presence of this vulnerability in Barracuda Spam Firewall 600 Firmware 3.5.11.020. The vendor has confirmed the issue exists in all versions prior to 3.5.11.025.
