  • Monitor HTTP POST requests to /bigUpload.php with query parameters 'action=upload', 'action=finish', and a 'key' parameter, which are characteristic of the multi-step exploit chain.
  • Detect path traversal sequences in the 'name' POST parameter of bigUpload.php targeting the web root at /home/MIX_CMIX/htmlroot/.
  • Alert on GET requests to newly created .php files in the web root (e.g., /ZSL.php) with query parameters used as command execution arguments (e.g., ?j=id), indicating successful webshell deployment.
  • The exploit runs as www-data (uid=33); monitor for unexpected process execution or file creation by the www-data user on ABB ASPECT/NEXUS/MATRIX devices.
  • ·The exploit targets ABB ASPECT-Enterprise, NEXUS Series, MATRIX-2 Series, and ASPECT-Studio all at firmware/software version 3.08.01; detections should be scoped to these specific product lines.
