HP OpenView NNM ovwebsnmpsrv.exe OVwSelection Stack Overflow Vulnerability
10 Dec. 2009
Summary
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.
Vulnerable Systems:
* HP OpenView Network Node Manager NNM
The specific flaw exists within the ovwebsnmpsrv.exe application which is launched when a request is received for the jovgraph.exe CGI application. This process copies the contents of the 'sel' POST variable a user-controllable amount of times into a static stack buffer. By repeating a specific string as the contents of the 'arg' POST variable this buffer can be overflowed leading to arbitrary code execution.
