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/?@vulndetector.com` | 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.
