Detection & IOCsextracted from sources · hover to see the quote

  • Trigger condition is processing a malformed HTTP message on SRX Series devices with ICAP redirect service enabled — monitor for anomalous/malformed HTTP traffic traversing SRX devices where ICAP redirect is active
  • The malformed HTTP message may originate from either direction — inspect both HTTP client-to-server and server-to-client traffic for malformed messages on ICAP-enabled SRX devices
  • ·Vulnerability only exists when ICAP (Internet Content Adaptation Protocol) redirect service is explicitly enabled on Juniper SRX Series devices — verify ICAP redirect service configuration before applying detection logic
  • ·Affected Junos OS versions on SRX Series: 18.1 prior to 18.1R3-S9; 18.2 prior to 18.2R2-S7/18.2R3-S3; 18.3 prior to 18.3R1-S7/18.3R2-S4/18.3R3-S1; 18.4 prior to 18.4R1-S7/18.4R2-S4/18.4R3; 19.1 prior to 19.1R1-S5/19.1R2; 19.2 prior to 19.2R1-S2/19.2R2; 19.3 prior to 19.3R2
  • ·Versions of Junos OS prior to 18.1R1 are NOT affected by this issue
