Official Description

Buffer overflow in nnmRptConfig.exe in HP OpenView Network Node Manager (OV NNM) 7.51 and 7.53 allows remote attackers to execute arbitrary code via a long nameParams parameter, a different vulnerability than CVE-2011-0267.2.

Source: NIST NVD / MITRE CVE Database

Attack Vector Analysis — CITED Relevance

The vulnerability is triggered by sending a specially crafted request with an excessively long nameParams parameter to the nnmRptConfig.exe service. This can lead to a buffer overflow, potentially allowing an attacker to execute arbitrary code with the privileges of the service.
