Multiple buffer overflows in nnmRptConfig.exe in HP OpenView Network Node Manager (OV NNM) 7.51 and 7.53 allow remote attackers to execute arbitrary code via a long (1) schdParams or (2) nameParams parameter, a different vulnerability than CVE-2011-0266.

  • Monitor HTTP POST requests to /OvCgi/nnmRptConfig.exe with abnormally large schdParams or nameParams parameter values (offset to SEH chain is 46919 bytes), indicative of a stack buffer overflow attempt.
  • Flag HTTP POST requests to /OvCgi/nnmRptConfig.exe containing bad characters \x00, \x26 (+), \x2b (&) stripped from payload — their absence in an oversized parameter body is characteristic of this exploit.
  • Detect use of SEH-based exploitation chain targeting OvWww.dll at RET address 0x5A30532D (POP/POP/RET gadget) on Windows Server 2003 targets running NNM 7.53.
  • Look for HTTP POST requests to /OvCgi/nnmRptConfig.exe with Content-Type: application/x-www-form-urlencoded and a body length consistent with ~46919+ bytes, as the exploit pads to the SEH offset with NOPs.
  • ·The Metasploit module only includes a single target (NNM 7.53 on Windows Server 2003 Ent); the RET address and offsets are specific to that platform/version combination and will not apply to NNM 7.51 or other OS targets without adjustment.
  • ·The exploit uses ExitFunction SEH and AutoRunScript migrate -f, meaning post-exploitation process migration is automatic; detections based solely on the nnmRptConfig.exe process may miss follow-on activity in a migrated process.
