# CVE-2017-7658: Jetty vulnerable to authorization bypass due to inconsistent HTTP request handling (HTTP Request Smuggling) > Attackers can bypass intermediary authorization checks by exploiting HTTP request smuggling via conflicting Content-Length headers in Jetty. - **Severity:** Critical 9.8 (`CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H`) - **Exploited in the wild:** Not known - **Login needed:** Not needed - **Attackable:** Over the internet - **Victim action needed:** Not needed - **Fix available:** Yes - **Published:** 26 Jun 2018 - **Updated:** 5 Aug 2024 - **Also known as:** CLEANSTART-2026-WA43103, CLSA-2026-1784769583, DEBIAN-CVE-2017-7658, GHSA-6x9x-8qw9-9pp6, UBUNTU-CVE-2017-7658 ## What is CVE-2017-7658? CVE-2017-7658 is a critical authentication bypass vulnerability in Debian Debian Linux, published on 26 Jun 2018. An attacker can exploit it over the internet without logging in, with no action from the victim. ### Official description 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. Weakness: CWE-444 (Inconsistent Interpretation of HTTP Requests) ## Which versions are affected by CVE-2017-7658? 6 open source packages ship an affected version, including org.eclipse.jetty:jetty-server.

Affected packages and fixed versions: - org.eclipse.jetty:jetty-server (Maven): affected all versions; fixed in 9.2.25.v20180606 - org.eclipse.jetty:jetty-server (Maven): affected all versions; fixed in 9.2.25.v20180606 - org.eclipse.jetty:jetty-server (Maven): affected from 9.3.0; fixed in 9.3.24.v20180605 - org.eclipse.jetty:jetty-server (Maven): affected from 9.3.0; fixed in 9.3.24.v20180605 - org.eclipse.jetty:jetty-server (Maven): affected from 9.4.0; fixed in 9.4.11.v20180605 - org.eclipse.jetty:jetty-server (Maven): affected from 9.4.0; fixed in 9.4.11.v20180605 Task: 1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies. 2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it. 3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead. 4. Run the tests and summarise what changed and why. 5. If nothing in the project is affected, say so and change nothing.
