Detection & IOCsextracted from sources · hover to see the quote

  • Node-RED server on Revolution Pi OS Bookworm 01/2025 has no authentication configured by default — detect unauthenticated remote access to the Node-RED HTTP endpoint (typically TCP/1880) from non-local sources as a strong indicator of exploitation
  • Monitor for arbitrary OS command execution originating from the Node-RED process on Revolution Pi devices, which would indicate successful exploitation of CVE-2025-24522
  • Alert on any inbound network connections to Revolution Pi devices on the Node-RED default port from internet-routable addresses; the vulnerability is exploitable remotely with low attack complexity and no authentication required (CVSS v3.1 10.0, AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H)
  • ·The vulnerability exists because Node-RED authentication is NOT configured by default on Revolution Pi OS Bookworm 01/2025 — affected versions are 01/2025 and earlier; a patched OS image was released 04/30/2025
  • ·No known public exploitation specifically targeting this vulnerability had been reported to CISA at time of advisory publication
