Multiple stack-based buffer overflows in HP OpenView Network Node Manager (OV NNM) 7.01, 7.51, and 7.53 allow remote attackers to execute arbitrary code via (1) long string parameters to the OpenView5.exe CGI program; (2) a long string parameter to the OpenView5.exe CGI program, related to ov.dll; or a long string parameter to the (3) getcvdata.exe, (4) ovlaunch.exe, or (5) Toolbar.exe CGI program.

  • Exploit sends a GET request to /OvCgi/Toolbar.exe with a query string of 5108+ random uppercase alpha characters followed by a 4-byte return address — look for abnormally long CGI query strings to this endpoint.
  • The exploit targets ov.dll for its return address (ROP gadget at 0x5a01d78d); presence of this address in HTTP traffic or memory is a strong indicator of exploitation.
  • Additional vulnerable CGI endpoints on the same OvCgi path include getcvdata.exe, ovlaunch.exe, and OpenView5.exe — monitor all for oversized query string parameters.
  • Payload bad characters include null bytes and common URL metacharacters; the exploit uses only uppercase alpha padding, so a query string of 5000+ uppercase letters to Toolbar.exe is highly suspicious.
  • ·The Metasploit module targets specifically HP OV NNM 7.50 on Windows 2000; the return address (0x5a01d78d in ov.dll) is version-specific and will not work against 7.01 or 7.53 without adjustment.
  • ·The CVE covers multiple affected CGI programs (OpenView5.exe, getcvdata.exe, ovlaunch.exe, Toolbar.exe); detection rules should cover all endpoints, not just Toolbar.exe.
