Title: Barracuda Hardcoded Password Vulnerability Severity: High (Sensitive Information Disclosure)
Date: 01 August 2006 Version Affected: Barracuda Spam Firewall version 3.3.01.001 to 3.3.03.053 Discovered by: Greg Sinclair ([EMAIL PROTECTED]) Discovered on: 28 May 2006 Overview: Barracuda Spam Firewalls (www.barracudanetworks.com) are vulnerable to information disclosure which is made possible by a default guest password Details: The Barracuda Spam Firewalls from version 3.3.01.001 to 3.3.02.053 have a hardcoded password for the "guest" account in the Login.pm script. This script is called to validate any user who attempts to login to the barracuda's web interface (typically at http://<deviceIP>:8080 or https://<deviceIP>). While the guest account has limited access, the following information can be obtained: * system configuration including IP accesses, admin IP ACLs * email message logs (but not the content of the messages) * version information of both spam/antivirus definitions and system firmware version Used in conjunction with the vulnerability "Barracuda Arbitrary File Disclosure" (NNL-20060801-02), the integrity of the system can be compromised. An attacker can use both vulnerabilities to download both confidential emails as well as the configuration information (including the admin password). Additionally, while some accounts such as "admin" are bound by user definable IP ACLs, the guest account is not. This means that sensitive information can be disclosed to ANY IP address regardless of the user defined network restrictions. Proof of Concept: Enter the username "guest" into the login page of any open barracuda and the password "bnadmin99" Recommendations: * Never allow your barracuda web interface to be accessible from untrusted networks (especially the Internet) * Upgrade to version 3.3.0.54 or later Vendor Contact: 29 May 2006 - Initial Vendor Contact 24 June 2006 - Vendor replies with prospect of fix 17 July 2006 - NNL request status update, no reply 01 Aug 2006 - NNL releases vuln report, notifies vendor of release
