Jetty invalid URI parsing may produce invalid HttpURI.authority

CVE-2022-2047 → View on GitHub ↗ View on CVE.org ↗ View on NVD ↗

Description

Description

URI use within Jetty's HttpURI class can parse invalid URIs such as http://localhost;/path as having an authority with a host of localhost;.

A URIs of the type http://localhost;/path should be interpreted to be either invalid or as localhost; to be the userinfo and no host.
However, HttpURI.host returns localhost; which is definitely wrong.

Impact

This can lead to errors with Jetty's HttpClient, and Jetty's ProxyServlet / AsyncProxyServlet / AsyncMiddleManServlet wrongly interpreting an authority with no host as one with a host.

Patches

Patched in PR #8146 for Jetty version 9.4.47.
Patched in PR #8014 for Jetty versions 10.0.10, and 11.0.10

Workarounds

None.

Attack vector (AV:N)
Could be attacked over the internet or any normal routed network—not just someone sitting at the machine.
Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:H)
They need powerful rights—admin, root, or similar—before this pays off.
User interaction (UI:N)
Nobody has to click “OK” or open a trap file; it can work without a victim helping.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:N)
Doesn’t really leak secrets in a meaningful way.
Integrity (I:L)
Attackers could change some data, but it’s limited—not everything goes.
Availability (A:N)
Service keeps running; no real outage angle.
