Title: ====== Sonicwall Scrutinizer v9.5.2 - SQL Injection Vulnerability Date: ===== 2013-02-13 References: =========== http://www.vulnerability-lab.com/get_content.php?id=789 #9984: Investigate Vulnerability Lab issues (this ticket included tracking the creation of our DBI shim to error on semi-colon) #10149: Create a common function to escape characters that can be used for SQL injection #10139: Review all mapping and flow analytics queries to make sure inputs included in SQL are escaped #10141: Review all reporting and filtering queries to make sure inputs included in SQL are escaped #10140: Review all alarm tab and admin tab queries to make sure inputs included in SQL are escaped VL-ID: ===== 789 Common Vulnerability Scoring System: ==================================== 7.3 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: ========= The Vulnerability Laboratory Research Team discovered SQL Injection vulnerability in the Dells Sonicwall OEM Scrutinizer v9.5.2 appliance application. Report-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 Disclosure Status: ======== Published Affected Products: ================== DELL Product: Sonicwall OEM Scrutinizer 9.5.2 Exploitation-Technique: ======================= Remote Severity: ========= High Details: ======== A blind SQL Injection vulnerability is detected in the Sonicwall OEM Scrutinizer v9.5.2 appliance application. The bug allows remote attackers to execute/inject own sql statement/commands to manipulate the affected vulnerable application dbms. The sql injection vulnerability is located in the fa_web.cgi file with the bound gadget listing module and the vulnerable orderby or gadget parameters. Exploitation requires no user interaction & without privileged application user account. Successful exploitation of the remote sql vulnerability results in dbms & application compromise. Vulnerable File(s): [+] fa_web.cgi Vulnerable Module(s): [+] gadget listing Vulnerable Parameter(s): [+] orderby [+] gadget Proof of Concept: ================= The remote sql injection vulnerability can be exploited by remote attackers without required privileged application user account and also without user interaction. For demonstration or reproduce ... PoC: http://127.0.0.1:1339/cgi-bin/fa_web.cgi?gadget=applicationsbytes-1%27[SQL INJECTION VULNERABILITY!]&orderby=1&cachebreaker=23_52_5_814-1%27 http://127.0.0.1:1339/cgi-bin/fa_web.cgi?gadget=applicationsbytes&orderby=-1%27[SQL INJECTION VULNERABILITY!]&cachebreaker=23_52_5_814-1%27 Solution: ========= 1) Scrutinizer team created a own DB layer that will die if a semicolon is found within a SQL query 2) We have changed more queries to pass inputs as bound variables to the DB engine which prevents possible SQL injection Risk: ===== The security risk of the remote sql injection vulnerability is estimated as high(+).
