I. Description

============================================================================



Vendor URL: http://www.openview.hp.com/



Delphis Consulting Internet Security Team (DCIST) discovered the following

vulnerability in HP Openview Node Manager under Windows NT.



Severity: high



By using the OverView5 CGI interface which is shipped and installed by

default with HPOpenView network node manager it is possible to cause a

BufferOverRun in SNMP.EXE. This is done be connecting to port 80 which the

WWW service resides on by default and sending a large GET string. The string



has to be a length of 132 + EIP (4 bytes making a total of 136 bytes). This

will cause the above application to BufferOverRun over writing EIP.



Example: (URL will be wrapped)

http://127.0.0.1/OvCgi/OpenView5.exe?Context=Snmp&Action=Snmp&Host=&Oid=A0B
