Multiple persistent Input Validation vulnerabilities are detected on Barracudas Control Center 620. Local low privileged user account can
implement/inject malicious persistent script code. When exploited by an authenticated user, the identified vulnerabilities
can lead to information disclosure, access to intranet available servers, manipulated persistent content.
Vulnerable Module(s): (Persistent)
[+] authdblookup -input
Multiple non-persistent Input Validation vulnerabilities are detected on Barracudas Control Center 620 appliance.
Attackers can form malicious client-side requests to hijack customer/admin sessions.
Successful exploitation requires user inter action & can lead to information disclosure, session
hijacking and access to servers in the intranet.
Vulnerable Module(s): (Non-Persistent)
Proof of Concept:
The vulnerabilities can be exploited by low privileged user accounts or remote attacker via high required user inter action.
For demonstration or reproduce ...
Manually reproduce ...
2. Switch to the vulnerable authdblookup-input.jsp add mask
3. Include your own malicious persistent script code (java-script or html) & save the input
4. The stored script code will be executed in main-bar as stable output result (persistent)
Barracuda implemented after the issues 2011 a validation mask to filter malicious & disallowed inputs.
The barracuda firmware of the filter has been update multiple times.
The security risk of the discovered persistent vulnerabilities are estimated as medium(+) because of low required user inter action.
The security risk of the discovered non-persistent vulnerabilities are estimated as low because of high required user inter action.
