In Eclipse Jetty Server, versions 9.2.x and older, 9.3.x (all non HTTP/1.x configurations), and 9.4.x (all HTTP/1.x configurations), when presented with two content-lengths headers, Jetty ignored the second. When presented with a content-length and a chunked encoding header, the content-length was ignored (as per RFC 2616). If an intermediary decided on the shorter length, but still passed on the longer body, then body content could be interpreted by Jetty as a pipelined request. If the intermediary was imposing authorization, the fake pipelined request would bypass that authorization.

Detection & IOCsextracted from sources · hover to see the quote

  • Detect HTTP requests with both a Content-Length header and a Transfer-Encoding: chunked header sent to Jetty servers — this dual-header pattern is the core smuggling vector for CVE-2017-7658
  • Detect HTTP requests with two distinct Content-Length headers targeting Jetty — Jetty silently drops the second value, enabling request smuggling when a front-end proxy honours the shorter one
  • Flag pipelined HTTP requests arriving at Jetty that originate from an intermediary/reverse-proxy, especially where the body length exceeds the Content-Length value declared by the proxy — the excess bytes are treated as a new pipelined request, potentially bypassing authorization
  • ·CVE-2017-7658 affects Jetty 9.2.x and older unconditionally; 9.3.x only in non-HTTP/1.x configurations; and 9.4.x only in HTTP/1.x configurations — scope detection rules accordingly
  • ·The vulnerability is exploitable only when Jetty sits behind an intermediary (reverse proxy, load balancer) that enforces authorization — direct exposure without an intermediary does not enable the authorization-bypass primitive
  • ·Red Hat Data Grid 7's agent-bond utility is the affected component in that product; it is deprecated and disabled by default — detection should target environments where agent-bond is explicitly enabled
  • ·Debian fixed the vulnerability in jetty package version 9.2.25-1 across all supported releases — use package version checks to confirm patched state
