Detection & IOCsextracted from sources · hover to see the quote

  • Target product is ControlID iDSecure On-premises versions 4.7.48.0 and prior; detect exploitation attempts against internet-exposed instances of this vehicle/access-control software
  • CVE-2025-49851 is network-exploitable with no authentication and low complexity (AV:N/AC:L/PR:N/UI:N); monitor for unauthenticated requests to iDSecure On-premises endpoints that result in elevated permissions or session tokens without prior credential exchange
  • Co-occurring vulnerabilities on the same product (CVE-2025-49852 SSRF, CVE-2025-49853 SQLi) suggest chained exploitation is likely; correlate authentication-bypass events with subsequent internal HTTP requests or anomalous SQL query patterns on the same host
  • Flag any iDSecure On-premises instance directly reachable from the internet; the advisory explicitly warns against internet exposure as a key risk factor
  • ·No known public exploitation has been reported at time of advisory publication; threat activity may be limited but the attack surface is broad (worldwide deployment, no auth required)
  • ·The advisory covers three CVEs (CVE-2025-49851 auth bypass, CVE-2025-49852 SSRF, CVE-2025-49853 SQLi) on the same product/version range; detection logic should account for all three when triaging alerts against iDSecure
