Solarwinds Storage Manager 5.1.0 SQL Injection

Solarwinds Storage Manager 5.1.0 SQL Injection
Posted May 6, 2012
Authored by muts, r@b13$, sinn3r | Site metasploit.com

This Metasploit module exploits a SQL injection found in Solarwinds Storage Manager login interface. It will send a malicious SQL query to create a JSP file under the web root directory, and then let it download and execute our malicious executable under the context of SYSTEM.
