Multiple stack-based buffer overflows in HP OpenView Network Node Manager (OV NNM) 6.41, 7.01, and 7.51 allow remote attackers to execute arbitrary code via unspecified long arguments to (1) ovlogin.exe, (2) OpenView5.exe, (3) snmpviewer.exe, and (4) webappmon.exe, as demonstrated via a long Action parameter to OpenView5.exe.

  • Detect HTTP GET requests to /OvCgi/OpenView5.exe with an abnormally long Action parameter (5123+ bytes) indicative of stack buffer overflow exploitation.
  • Payload bad characters for this exploit are null byte, colon, ampersand, question mark, percent, hash, space, CR, LF, forward slash, plus, vertical tab, and backslash — useful for tuning IDS/WAF signatures.
  • The Metasploit module uses a return address from ov.dll (0x5a01d78d) for NNM 7.50 on Windows 2000; the PoC uses JMP ESP from user32.dll (0x77e14c29) on Win2kSP4 — monitor for these RET addresses in HTTP POST/GET bodies targeting OvCgi.
  • Alert on HTTP GET requests to any of the four vulnerable CGI binaries (ovlogin.exe, OpenView5.exe, snmpviewer.exe, webappmon.exe) under /OvCgi/ with unusually long query string parameters.
  • The exploit opens a reverse shell on port 4444; monitor for unexpected outbound connections from the HP OpenView server process to port 4444.
  • ·The Metasploit module targets specifically NNM 7.50 on Windows 2000 (all); the NVD advisory lists affected versions as 6.41, 7.01, and 7.51 — the return address (ov.dll) will differ across versions and platforms.
  • ·The Python PoC was tested only on NNM Release B.07.50 / Windows 2000 Server SP4; the JMP ESP address (0x77e14c29 from user32.dll) is specific to that OS/SP combination and will not be reliable on other targets.
