Upgrade org.eclipse.jetty:jetty-http to version 12.0.12 or higher.
Overview
org.eclipse.jetty:jetty-http is an is a http module for jetty server.
Affected versions of this package are vulnerable to Improper Validation of Syntactic Correctness of Input via the HttpURI class due to insufficient validation on the authority segment of a URI. An attacker can manipulate the URI parsing to redirect requests or initiate server-side requests to unintended destinations by supplying malformed URIs that bypass validation checks.
Notes:
This is only exploitable if the application uses decoded user data as encoded URIs in conjunction with the
HttpURIclass used directly;The Jetty usage of the
HttpURIclass is not vulnerable.
Workaround
This vulnerability can be mitigated by not passing decoded user data as encoded URIs to any URI class/method, including HttpURI.
