TITLE

Barracuda Spam Firewall contains hardcoded default login credentials

DESCRIPTION

Directory traversal vulnerability in cgi-bin/preview_email.cgi in Barracuda Spam Firewall (BSF) 3.3.01.001 through 3.3.03.053 allows remote authenticated users to read arbitrary files via a .. (dot dot) in the file parameter. Barracuda Spam Firewalls from version 3.3.01.001 to 3.3.02.053 have default login credentials that can not be modified by an administrator. Spam Firewall is prone to multiple vulnerabilities, including a directory-traversal issue, access-validation issue, and a remote command-execution issue. A remote attacker can exploit these issues to gain access to potentially sensitive information and execute commands in the context of the affected application. Versions 3.3.01.001 to 3.3.03.055 are vulnerable to these issues. Barracuda Spam Firewall is an integrated hardware and software spam solution for protecting mail servers. Although the guest account has only limited access, the following information can be obtained: * System configuration, including IP address, administrator IP ACL; * Email message log (but not the content of the message); * Spam/antivirus definition version information and system firmware version. There is also a file disclosure vulnerability in Barracuda's preview_email.cgi script. This script was used to retrieve messages from Barracuda's local message database, but did not properly filter the file parameter passed through GET to limit file retrieval to the message database directory, resulting in access to any Web Server user accessible files from the web interface. In addition, it is possible to execute arbitrary commands using the pipe symbol (|). Although this script requires a valid user login, this restriction can be easily bypassed by combining the guest password vulnerability described above. ---------------------------------------------------------------------- Hardcore Disassembler / Reverse Engineer Wanted!

This can be exploited to disclose the contents of arbitrary files via directory traversal attacks (e.g. message logs). Example: https://[host]/cgi-bin/preview_email.cgi?file=/mail/mlog/../[file] Successful exploitation requires that the user has been authenticated. 2) A default guest account with a hard-coded password exists in Login.pm. This can be exploited to disclose various configuration and version information. A combination of the two issues can be exploited by a malicious person to disclose the contents of arbitrary files. The vulnerability and the security issue have been reported in firmware versions 3.3.01.001 through 3.3.03.053. SOLUTION: Update to firmware version 3.3.0.54.
