Report-Timeline: ================ 2012-11-27: Researcher Notification & Coordination (Benjamin Kunz Mejri) 2012-11-28: Vendor Notification (Barracuda Networks Security - Bug Bounty Program) 2012-12-01: Vendor Response/Feedback (Barracuda Networks Security - Bug Bounty Program) 2013-03-14: Vendor Fix/Patch (Barracuda Networks Developer) [Coordination: Dave Farrow] 2012-06-25: Public Disclosure (Vulnerability Laboratory) Status: ======== Published Affected Products: ================== Barracuda Networks Product: CudaTel - Communication Server 2.6.002.040 Exploitation-Technique: ======================= Remote Severity: ========= Medium Details: ======== Multiple client side input validation vulnerabilities are detected in the Barracuda Networks CudaTel v2.6.002.040 appliance application. The non-persistent vulnerabilities allows an attacker (remote) to manipulate client side application to browser requests. The vulnerability (client side) is located in the siplist and list module when processing to request manipulated bbx_provider_gateway_name, bbx_provider_gateway_username or bbx_provider_gateway_host parameter listing. Exploitation of the vulnerability requires medium application user interaction. Successful exploitation of the vulnerability results in client side phishing, client side session hijacking, client side external redirects to malware or evil websites and client side module context manipulation(cache). Vulnerable Module(s): [+] siplist - Listing [+] list - Listing Vulnerable Parameter(s): [+] bbx_provider_gateway_name [+] bbx_provider_gateway_username [+] bbx_provider_gateway_host Proof of Concept: ================= The client side input validation vulnerabilities can be exploited by remote attackers without required application user account and with medium or high required user interaction.
