Description

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.

How this vulnerability can be exploited

This issue can be reached over the network, attack complexity is high, an attacker needs no privileges on the target. No user interaction is required. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality none, integrity low, availability none.

Weakness class

CVE-2025-11143 is classified as CWE-20: Improper Input Validation. The application accepts input without checking that it has the expected form, so malformed values reach code that assumes they are well formed.

Affected software

CVE-2025-11143 is recorded against 2 packages.

  • jetty (from 12.1.0 up to 12.1.5)
  • org.eclipse.jetty:jetty-http (from 12.1.0 up to 12.1.5)
