Summary

Eclipse Jetty is prone to an information disclosure vulnerability.

Insight

Insight

Release 9.4.37 introduced a more precise implementation of RFC3986 with regards to URI decoding, together with some new compliance modes to optionally allow support of some URI that may have ambiguous interpretation within the Servlet specified API methods behaviours. The default mode allowed % encoded . characters to be excluded for URI normalisation, which is correct by the RFC, but is not assumed by common Servlet implementations.

Affected Software

Affected Software

Eclipse Jetty versions 9.4.37.v20210219 and 9.4.38.v20210224.

Detection Method

Detection Method

Checks if a vulnerable version is present on the target host.

Solution

Solution

Update to version 9.4.39 or later. Please see the referenced vendor advisory for a possible workaround.
