Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
CRLF injection vulnerability in Mortbay Jetty before 6.1.6rc0 allows remote attackers to inject arbitrary HTTP headers and conduct HTTP response splitting attacks via unspecified vectors.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

CRLF injection vulnerability in Mortbay Jetty versions prior to 6.1.6rc0 allows remote attackers to inject arbitrary HTTP headers by inserting carriage return and line feed (CRLF) sequences into input fields. This enables HTTP response splitting attacks where malicious headers or response bodies can be injected into server responses, potentially leading to cross-site scripting (XSS), cache poisoning, or session hijacking.

MitigationUpgrade Mortbay Jetty to version 6.1.6rc0 or later. If upgrading is not feasible, implement input validation to reject requests containing CRLF sequences in user-supplied data.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify Jetty version from JAR manifest
    Locate the jetty.jar or start.jar file in the Jetty installation directory and inspect its META-INF/MANIFEST.MF file for the Implementation-Version or Bundle-Version attribute
    Affected if The version listed is 6.1.6rc0 or earlier, or if no version is displayed and the installation dates to before late 2007
  2. Check Jetty version from startup logs
    Review the console output or log files generated when Jetty starts, as the version is typically printed during startup
    Affected if The startup logs show a version of 6.1.6rc0 or earlier
  3. Verify Jetty is the HTTP server in use
    Run a command such as 'netstat -an' or 'ss -tlnp' to list listening ports, then access the server via HTTP to observe default error pages or check for 'Jetty' in server response headers
    Affected if The server identifies itself as Mortbay Jetty or Eclipse Jetty version 6.x and the version is 6.1.6rc0 or earlier
  4. Confirm the server handles user input
    Submit test requests with CRLF sequences (%0D%0A URL-encoded) in query parameters or form inputs to observe whether the server reflects these characters in its response headers
    Affected if The server returns the CRLF sequences unmodified in response headers, indicating the injection vulnerability is present

A user is affected if their Mortbay Jetty installation shows version 6.1.6rc0 or any earlier 6.x version, and the server processes user-supplied input that could be reflected in HTTP headers.

From vendor data
Upgrade available Upgrade to a release after 6.1.6rc0
Interim mitigation

Upgrade Mortbay Jetty to version 6.1.6rc0 or later. If upgrading is not feasible, implement input validation to reject requests containing CRLF sequences in user-supplied data.
