CVE-2010-20109

8.7 HIGH 2% exploit odds No fix listed Disclosure Network gear

What it is

Barracuda products, confirmed in Spam & Virus Firewall, SSL VPN, and Web Application Firewall versions prior to October 2010, contain a path traversal vulnerability in the view_help.cgi endpoint. The locale parameter fails to properly sanitize user input, allowing attackers to inject traversal sequences and null-byte terminators to access arbitrary files on the underlying system. By exploiting this flaw, unauthenticated remote attackers can retrieve sensitive configuration files such as /mail/snapshot/config.snapshot, potentially exposing credentials, internal settings, and other critical data.

At a glance

Exploitability: Can be exploited over the network without logging in. High risk of data exposure.
Exploit odds: 1.7% chance of exploitation in the next 30 days (EPSS).
Fix: No patch or advisory is linked yet. Look at mitigations or restrict exposure.
