CVE-2008-2438: Integer overflow in ovalarmsrv.exe in HP OpenView Network Node Manager (OV NNM) 7.01, 7.51, and 7.53 allows...

Security readout for executives and security teams

This flaw affects older HP OpenView Network Node Manager servers. A remote attacker could send a crafted request to the alarm service on TCP port 2954 and potentially run code on the management server. Because NNM often has privileged network visibility, compromise could create serious operational risk. Exposure is most likely where HP OpenView NNM 7.01, 7.51, or 7.53 is still deployed and ovalarmsrv is reachable on TCP/2954. Internet exposure would be especially concerning, but internal-only exposure still matters because this is a network management platform. Treat this as high-priority legacy infrastructure risk. If affected NNM servers remain active, focus first on reachability reduction, vendor guidance, and upgrade or retirement planning. The urgency increases sharply if TCP/2954 is exposed beyond a tightly controlled management network. Mitigation focus: Check HP advisory HPSBMA02424 for official updates, fixes, or supported upgrade paths.; Restrict TCP/2954 to trusted management networks only.; Remove internet exposure for affected NNM services immediately..
