Package

maven jetty-http (Maven)

Affected versions

<=9.4.46,<=10.0.9,<=11.0.9

Patched versions

9.4.47,10.0.10,11.0.10

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.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
