What it detects
This rule detects HTTP requests containing Apache Camel exec-command headers used to bypass the header filter in CVE-2025-27636 and CVE-2025-29891. Attackers inject CamelExecCommandExecutable and CamelExecCommandArgs headers to run arbitrary commands on vulnerable Camel routes. Presence of these headers in inbound traffic indicates exploitation attempts.
