CVE-2010-2703: Stack-based buffer overflow in the execvp_nc function in the ov.dll module in HP OpenView Network Node Mana...

Security readout for executives and security teams

This is a remote code execution flaw in HP OpenView Network Node Manager 7.51 and 7.53 on Windows. A remote attacker could crash or take control of the service through an overlong HTTP request to webappmon.exe. Treat exposed legacy NNM systems as urgent because this product is old and public exploit references exist. Exposure is likely limited to organizations still running HP OpenView Network Node Manager 7.51 or 7.53 on Windows, especially where NNM web components are reachable from untrusted networks. Prioritize remediation for any exposed or business-critical NNM server. This is legacy infrastructure with remote code execution impact and public exploit references, but no supplied evidence of active exploitation. Mitigation focus: Check HP SSRT100025 and apply the vendor-recommended update or workaround.; Remove or replace unsupported HP OV NNM 7.51 and 7.53 Windows deployments.; Restrict access to NNM web interfaces to trusted management networks only..
