  • Detect exploit traffic targeting magentproc.exe on TCP/443 (SSL3): look for inbound SSL3 connections carrying a packet whose first 4 bytes are 0xFFFFFFFF (fake XDR length field) followed by a large payload exceeding ~6000 bytes.
  • The exploit forces SSL version SSL3 and uses PrependMigrate; alert on SSL3 negotiation to port 443 on LoadRunner agent hosts (magentproc.exe listeners).
  • The Nessus plugin hp_loadrunner_cve-2013-4800.nasl can be used to detect vulnerable HP LoadRunner agent instances.
  • Stack adjustment shellcode prepend bytes 0x81 0xC4 0x54 0xF2 0xFF 0xFF (add esp, -3500) will appear immediately before the payload; scan for this byte sequence in SSL3 traffic to port 443 on LoadRunner agent hosts.
  • ·The Metasploit module targets only Windows XP SP3 with HP LoadRunner 11.50 (magentproc.exe version 11.50.2042.0); the RET gadget 0x7ffc070e is sourced from NLS tables and may not be stable on other OS patch levels.
  • ·Null byte (0x00) is a bad character for the payload encoder; payloads containing null bytes will be broken by the target service.
  • ·A crash length of 6000 bytes is required to reliably trigger the exception; shorter payloads may not reach the SEH overwrite.
