'Name'=> 'HP Operations Agent Opcode coda.exe 0x8c Buffer Overflow',
'Description'=> %q{
This module exploits a buffer overflow vulnerability in HP Operations Agent for
Windows. The vulnerability exists in the HP Software Performance Core Program
component (coda.exe) when parsing requests for the 0x8c opcode. This module has
been tested successfully on HP Operations Agent 11.00 over Windows XP SP3 and
Windows 2003 SP2 (DEP bypass).
The coda.exe components runs only for localhost by default, network access must be
granted through its configuration to be remotely exploitable. On the other hand it
runs on a random TCP port, to make easier reconnaissance a check function is
provided.
