HP Power Manager 'formExportDataLogs' Buffer Overflow

HP Power Manager 'formExportDataLogs' Buffer Overflow
Posted Oct 20, 2011
Authored by Alin Rad Pop, sinn3r, ipax | Site metasploit.com

This Metasploit module exploits a buffer overflow in HP Power Manager's 'formExportDataLogs'. By creating a malformed request specifically for the fileName parameter, a stack-based buffer overflow occurs due to a long error message (which contains the fileName), which may result in arbitrary remote code execution under the context of 'SYSTEM'.
