org.eclipse.jetty:jetty-http has different parsing of invalid URIs

The Jetty URI parser has some key differences compared to other common parsers when evaluating invalid or unusual URIs. Specifically: #### Invalid Scheme | URI | Jetty | uri-js (nodejs) | node-url(nodejs) | |---|---|---| --- | | `https>://vulndetector.com/path` | scheme=`http>`| scheme=`https` | invalid URI | #### Improper IPv4 mapped IPv6 | URI | Jetty | System.Uri(CSharp) | curl(C) | |---|---|---| --- | | `http://[0:0:0:0:0:ffff:127.0.0.1]` | invalid | host=`[::ffff:127.0.0.1]` | host=`[::ffff:127.0.0.1]` | | `http://[::ffff:255.255.0.0]` | invalid | host=`[::ffff:255.255.0.0]` | host=`[::ffff:255.255.0.0]` | #### Incorrect IPv6 delimeter priority | URI | Jetty | urllib3(python) | furl(python) | Spring | chromium | |---|---|---| --- |---|---| | `http://[normal.com@]vulndetector.com/` | host=`[normal.com@]` | invalid | invalid | | | | `http://normal.com[user@vulndetector].com/` | host=`[noirmal.com@vulndetector | | | host=`normal.com` | invalid | | `http://normal.com[@]vulndetector.com/` | host=`normal.com[@] | | | host=`normal.com` | invalid | #### Incorrect delimeter priority | URI | Jetty | urllib3(python) | jersey | |---|---|---| --- | | `http://normal.com/#@vulndetector.com` | host=`vulndetector.com` | host=`normal.com` | host=`normal.com` | | `http://normal.com/[email protected]` | host=`vulndetector.com` | host=`normal.com` | host=`normal.com` | ### Impact Differential parsing of URIs in systems using multiple components may result in security by-pass. For example a component that enforces a black list may interpret the URIs differently from one that generates a response. At the very least, differential parsing may divulge implementation details. ### Patches Patched in Supported Open Source versions. * 12.1.5 - Supported and available on Maven Central * 12.0.31 - Supported and available on Maven Central * 11.0.x - EOL Release, patches available on [tuxcare](https://tuxcare.com/) and [herodevs](https://www.herodevs.com/) * 10.0.x - EOL Release, patches available on [tuxcare](https://tuxcare.com/) and [herodevs](https://www.herodevs.com/) * 9.4.x - EOL Release, patches available on [tuxcare](https://tuxcare.com/) and [herodevs](https://www.herodevs.com/) ### Workarounds None ### Resources + [Java Eclipse Jetty Report_ Incorrect Parsing Priority of the IPv6 Hostname Delimeter.pdf](https://github.com/user-attachments/files/22222625/Java.Eclipse.Jetty.Report_.Incorrect.Parsing.Priority.of.the.IPv6.Hostname.Delimeter.pdf) + [Java Eclipse Jetty Report_ The Parsing Priority of the Delimiter.pdf](https://github.com/user-attachments/files/22222626/Java.Eclipse.Jetty.Report_.The.Parsing.Priority.of.the.Delimiter.pdf) + [Java Eclipse Jetty Report_ Parsing Difference Due to Deformed Scheme.pdf](https://github.com/user-attachments/files/22222627/Java.Eclipse.Jetty.Report_.Parsing.Difference.Due.to.Deformed.Scheme.pdf) + [Java Eclipse Jetty Report_ Improper IPv4-mapped IPv6 Parsing.pdf](https://github.com/user-attachments/files/22222630/Java.Eclipse.Jetty.Report_.Improper.IPv4-mapped.IPv6.Parsing.pdf)
