Praetorian503 Posted February 13, 2013 Report Posted February 13, 2013 Sonicwall Scrutinizer version 9.5.2 suffers from a remote blind SQL injection vulnerability.Title:======Sonicwall Scrutinizer v9.5.2 - SQL Injection VulnerabilityDate:=====2013-02-13References:===========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 escapedVL-ID:=====789Common Vulnerability Scoring System:====================================7.3Introduction:=============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.

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.cgiVulnerable Module(s): [+] gadget listingVulnerable Parameter(s): [+] orderby [+] gadgetProof 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%27http://127.0.0.1:1339/cgi-bin/fa_web.cgi?gadget=applicationsbytes&orderby=-1%27[SQL INJECTION VULNERABILITY!]&cachebreaker=23_52_5_814-1%27Solution:=========1) Scrutinizer team created a own DB layer that will die if a semicolon is found within a SQL query2) We have changed more queries to pass inputs as bound variables to the DB engine which prevents possible SQL injectionRisk:=====The security risk of the remote sql injection vulnerability is estimated as high(+).Credits:========Vulnerability Laboratory [Research Team] - Benjamin Kunz Mejri (bkm@vulnerability-lab.com)Disclaimer:===========The information provided in this advisory is provided as it is without any warranty.
