Zero Day Initiative Advisory 11-005
Posted Jan 12, 2011
Authored by Tipping Point | Site zerodayinitiative.com

Zero Day Initiative Advisory 11-05 - This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Hewlett-Packard OpenView Network Node Manager. Authentication is not required to exploit this vulnerability. The flaw exists within the ovas.exe component which listens by default on TCP port 7510. When handling the Source Node or Destination Node name POST variables the process blindly copies user supplied data into a fixed-length buffer on the stack. A remote attacker can exploit this vulnerability to execute arbitrary code under the context of the OVAS service.
