  • Monitor for execution of the SUID binary `omniresolve` with a manipulated PATH environment variable (PATH containing /tmp or other writable directories prepended), which is the core exploit primitive.
  • Alert on creation of a file named `oracleasm` in world-writable directories (e.g. /tmp) followed by execution of `/opt/omni/lbin/omniresolve`, indicating PATH hijacking of the trusted SUID binary.
  • Detect privilege escalation by checking if processes spawned by `/opt/omni/lbin/omniresolve` run as root while the parent process is a low-privileged user; the binary is SUID and should be audited for unexpected child processes.
  • Flag vulnerable builds of omniresolve: internal build 118 or lower (e.g. build 110, build 118) are exploitable; patched build is 125 or higher. Use `omniresolve -ver` output to identify vulnerable instances.
  • ·The exploit requires an existing low-privileged shell or Meterpreter session on the target; it is a local privilege escalation, not a remote exploit.
  • ·The writable directory (default /tmp) must be writable by the attacker's session for the payload drop and PATH hijack to succeed.
  • ·The vulnerability is patched in Micro Focus Data Protector A.10.40 OMNIRESOLVE internal build 125; builds at or below 118 on version 10.40 (and all prior versions) remain vulnerable.
