The documentation of Apache Tomcat 10.1.0-M1 to 10.1.0-M14, 10.0.0-M1 to 10.0.20, 9.0.13 to 9.0.62 and 8.5.38 to 8.5.78 for the EncryptInterceptor incorrectly stated it enabled Tomcat clustering to run over an untrusted network. This was not correct. While the EncryptInterceptor does provide confidentiality and integrity protection, it does not protect against all risks associated with running over any untrusted network, particularly DoS risks.

FLT2002
  • Detect large repeated TCP payloads beginning with the magic bytes 'FLT2002' sent to the Tomcat clustering port (default 4000); multiple concurrent connections sending this pattern indicate a DoS attempt exploiting CVE-2022-29885.
  • The exploit spawns 5 concurrent threads each sending the malformed cluster message in a tight loop; high-volume concurrent connections to the clustering port from a single source should be alerted on.
  • CVE-2022-29885 is exploitable even when EncryptInterceptor is enabled; presence of EncryptInterceptor in Tomcat cluster config does NOT rule out DoS exposure over untrusted networks.
  • ·EncryptInterceptor provides confidentiality and integrity but does NOT protect against DoS risks on untrusted networks, contrary to prior documentation claims.
  • ·Tomcat clustering exposed on any untrusted or public network segment remains vulnerable to DoS regardless of EncryptInterceptor configuration; a VPN or equivalent network isolation is required for full protection.
