Signature Detail

APP: HP OpenView Network Node Manager ovsessionmgr.exe Buffer Overflow

This signature detects attempts to exploit a known vulnerability against HP OpenView Network Node Manager (NNM). The vulnerability is due to a boundary error in ovsessionmgr.exe when processing the 'userid' and 'passwd' parameters sent in an HTTP POST request. A remote unauthenticated attacker can exploit this vulnerability by sending a crafted HTTP request to a target server, potentially causing arbitrary code to be injected and executed in the security context of the SYSTEM user. In an attack scenario, where arbitrary code is injected and executed on the target machine, the behavior of the target is dependent on the logic of the malicious code.

Extended Description

HP OpenView Network Node Manager is prone to a remote heap-based buffer-overflow vulnerability. An attacker can exploit this issue to execute arbitrary code with SYSTEM-level privileges. Successful exploits will completely compromise affected computers. Failed exploit attempts will result in a denial-of-service condition. NOTE: This issue was previously covered in BID 37261 (HP OpenView Network Node Manager Multiple Remote Code Execution Vulnerabilities), but has been assigned its own record to better document it.
