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.
Barracuda Spam Firewall is prone to a cross-site scripting vulnerability because the application fails to properly sanitize user-supplied input. An attacker may leverage this issue to execute arbitrary script code in the browser of an unsuspecting user in the context of the affected site. This may help the attacker steal cookie-based authentication credentials and launch other attacks.
