The NSA 2400 integrates dual-core hardware, SonicWALL Reassembly-Free Deep Packet Inspection™, intrusion prevention, application control, and SSL VPN, for real-time protection without compromising performance. (Copy of the Vendor Homepage: http://www.sonicwall.com/de/en/products/NSA_2400.html ) Abstract Advisory Information: ============================== The Vulnerability Laboratory Research Team discovered a client-side cross site scripting web vulnerability in the SonicWall backend servers with which firewalls communicate. Vulnerability Disclosure Timeline: ================================== 2013-09-26: Researcher Notification & Coordination (Benjamin Kunz Mejri) 2013-09-27: Vendor Notification (DELL SonicWall Security Team) 2014-10-06: Vendor Response/Feedback (DELL SonicWall Security Team) 2014-02-18: Vendor Fix/Patch (DELL SonicWall Developer Team) 2014-03-06: Public Disclosure (Vulnerability Laboratory) Discovery Status: ================= Published Exploitation Technique: ======================= Remote Severity Level: =============== Low Technical Details & Description: ================================ A client-side cross site scripting web vulnerability has been discovered in the SonicWall backend web-server with which appliance firewalls communicate. The cross site scripting web vulnerability allows an attacker to manipulate client-side browser requests through a vulnerable application module/function. The cross site scripting vulnerability is located in the dashboard.jsp file when processing to request via GET method manipulated `sn` values. The injected script code executes on the client-side of the web-application in the dashboard resource checkbox listing backend. This issue affects sonicwall backend servers with which firewalls communicate. The attack vector is non-persistent (client-side) and the request method is GET. The security risk of the client-side web vulnerability is estimated as low(+) with a cvss (common vulnerability scoring system) count of 2.0(+)|(-)2.1. Exploitation of the client-side web vulnerability requires no privileged web-application user account but low or medium user interaction. Successful exploitation of the vulnerability results in session hijacking, client-side phishing, client-side external redirects, malicious GET method requests and client-side manipulation of the vulnerable or connected module context. Request Method(s): [+] [GET] Vulnerable Module(s): [+] stats Vulnerable File(s): [+] dashboard.jsp Vulnerable Parameter(s): [+] sn Proof of Concept (PoC): ======================= The client-side cross site scripting web vulnerability can be exploited by remote attackers without privileged application user account and with low or medium user interaction.

Backend servers have been updated with the fix for this issue on 02/18/2014. Security Risk: ============== The security risk of the client-side cross site scripting web vulnerability is estimated as low(+).
