Document Title: =============== Sonicwall OEM Scrutinizer v9.5.2 - Multiple Vulnerabilities References (Source): ==================== http://www.vulnerability-lab.com/get_content.php?id=786 Release Date: ============= 2013-02-13 Vulnerability Laboratory ID (VL-ID): ==================================== 786 Common Vulnerability Scoring System: ==================================== 5.2 Product & Service Introduction: =============================== Dell™ SonicWALL™ Scrutinizer is a multi-vendor, flow-based application traffic analytics, visualization and reporting tool to measure and troubleshoot network performance and utilization while increasing productivity for enterprises and service providers. Scrutinizer supports a wide range of routers, switches, firewalls, and data-flow reporting protocols, providing unparalleled insight into application traffic analysis from IPFIX/NetFlow data exported by Dell SonicWALL firewalls, as well as support for a wide range of routers, switches, firewalls, and data-flow reporting protocols. IT administrators in charge of high throughput networks can deploy Scrutinizer as a virtual appliance for high performance environments. (Copy of the Vendor Homepage: http://www.sonicwall.com/us/en/products/Scrutinizer.html ) Abstract Advisory Information: ============================== The Vulnerability Laboratory Research Team discovered multiple web vulnerabilities in the Dell Sonicwall OEM Scrutinizer v9.5.2 appliance application. Vulnerability Disclosure Timeline: ================================== 2012-12-05: Researcher Notification & Coordination 2012-12-07: Vendor Notification 2013-01-08: Vendor Response/Feedback 2013-02-10: Vendor Fix/Patch 2013-02-11: Public or Non-Public Disclosure Discovery Status: ================= Published Affected Product(s): ==================== DELL Product: Sonicwall OEM Scrutinizer 9.5.2 Exploitation Technique: ======================= Remote Severity Level: =============== Medium Technical Details & Description: ================================ Multiple persistent input validation vulnerabilities are detected in the Sonicwall OEM Scrutinizer v9.5.2 appliance application. The bugs allows remote attackers to implement/inject malicious script code on the application-side (persistent). The first persistent vulnerability is located in the Alarm - New Board & Policy Manager module with the bound vulnerable Search item - BBSearchText parameter request. The vulnerability allows to inject persistent script code as search item value. The result is the persistent execution of script code out of the BBSearchText listing. The second persistent vulnerability is located in the Dashboard - Flow Expert module with the bound vulnerable Mytab parameter. The vulnerability allows to inject persistent script code as myTab link value. The result is the persistent execution of script code out of the Mytab link listing. The 3rd persistent vulnerability is located in the MyView (CGI) module with the bound vulnerable `newName` parameter request. The vulnerability allows to inject persistent script code as newName. The result is the persistent execution of script code out of the core value listing. The 4th persistent vulnerability is located in the Admin > Admin [New Users & New Group] module with the bound vulnerable groupName & username parameters. The vulnerability allows to inject persistent script code as username or groupname. The result is the persistent execution of script code out of all username and group listings + checkboxes. The 5th persistent vulnerability is located in the Admin > Admin [Mapping / Maps (CGI) - Dashboard Status] module with the bound vulnerable groupMembers, Type, Checkbox Linklike, indexColumn, name, Object Name & settings groups(checkbox) parameters. The vulnerability allows to inject persistent script code as groupMembers, Type, Checkbox Linklike, indexColumn, name, Object Name & settings groups(checkbox) value(s). The result is the persistent execution of script code out of the groupMembers, Type, Checkbox Linklike, indexColumn, name, Object Name listings and settings groups checkbox. The 6th persistent vulnerability is located in the Alarms > Overview Bulletin Board > Advanced Filters module with the bound vulnerable displayBBAdvFilterModal() - (Policy Name, Board Name, Violators) parameters. The vulnerability allows to inject persistent script code as Policy Name, Board Name and Violator. The result is the persistent execution of script code out of the Policy Name, Board Name and Violator listings. Successful exploitation of the vulnerability can lead to persistent session hijacking (manager/admin), persistent phishing, persistent external redirects to malware or scam and persistent web context manipulation in the affected vulnerable module(s). Exploitation requires low user interaction & a low privileged appliance web application user account.

Solution - Fix & Patch: ======================= 2013-02-10: Vendor Fix/Patch Where changing code paths to use bound variables was not practical in such a short timeframe, we pass inputs included in a query through a function that escapes potentially dangerous characters. Security Risk: ============== The security risk of the persistent input validation web vulnerabilities are estimated as medium(+)|(-)high.
