Eclipse Jetty URI parsing of invalid authority ## Summary Eclipse Jetty is a lightweight, highly scalable, Java-based web server and Servlet engine . It includes a utility class, `HttpURI`, for URI/URL parsing. The `HttpURI` class does insufficient validation on the authority segment of a URI. However the behaviour of `HttpURI` differs from the common browsers in how it handles a URI that would be considered invalid if fully validated against the RRC. Specifically `HttpURI` and the browser may differ on the value of the host extracted from an invalid URI and thus a combination of Jetty and a vulnerable browser may be vulnerable to a open redirect attack or to a SSRF attack if the URI is used after passing validation checks. ## Details ### Affected components The vulnerable component is the `HttpURI` class when used as a utility class in an application. The Jetty usage of the class is not vulnerable. ### Attack overview The `HttpURI` class does not well validate the authority section of a URI. When presented with an illegal authority that may contain user info (eg username:password#@hostname:port), then the parsing of the URI is not failed. Moreover, the interpretation of what part of the authority is the host name differs from a common browser in that they also do not fail, but they select a different host name from the illegal URI. ### Attack scenario A typical attack scenario is illustrated in the diagram below. The Validator checks whether the attacker-supplied URL is on the blocklist. If not, the URI is passed to the Requester for redirection. The Requester is responsible for sending requests to the hostname specified by the URI. This attack occurs when the Validator is the `org.eclipse.jetty.http.HttpURI` class and the Requester is the `Browser` (include chrome, firefox and Safari). An attacker can send a malformed URI to the Validator (e.g., `http://browser.check%23%40vulndetector.com/` ). After validation, the Validator finds that the hostname is not on the blocklist. However, the Requester can still send requests to the domain with the hostname `vulndetector.com`. ## PoC payloads: ``` http://browser.check &@vulndetector.com/ http://browser.check #@vulndetector.com/ http://browser.check?@vulndetector.com/ http://browser.check#@vulndetector.com/ http://vulndetector.com\\/ ``` The problem of 302 redirect parsing in HTML tag scenarios. Below is a poc example. After clicking the button, the browser will open "browser.check", and jetty will parse this URL as "vulndetector.com". ``` <a href="http://browser.check#@vulndetector.com/"></a> ``` A comparison of the parsing differences between Jetty and chrome is shown in the table below (note that neither should accept the URI as valid). | Invalid URI | Jetty | Chrome | | ---------------------------------------------- | ---------------- | ------------- | | http://browser.check &@vulndetector.com/ | vulndetector.com | browser.check | | http://browser.check #@vulndetector.com/ | vulndetector.com | browser.check | | http://browser.check?@vulndetector.com/ | vulndetector.com | browser.check | | http://browser.check#@vulndetector.com/ | vulndetector.com | browser.check | The problem of 302 redirect parsing in HTTP 302 Location | Input | Jetty | Chrome | | ------------------------ | -------------- | ------------- | | http://browser.check%5c/ | browser.check\ | browser.check | It is noteworthy that Spring Web also faced similar security vulnerabilities, being affected by the aforementioned four types of payloads. These issues have since been resolved and have been assigned three CVE numbers [3-5]. ## Impact The impact of this vulnerability is limited to developers that use the Jetty HttpURI directly. Example: your project implemented a blocklist to block on some hosts based on HttpURI's handling of authority section. The vulnerability will help attackers bypass the protections that developers have set up for hosts. The vulnerability will lead to **SSRF**[1] and **URL Redirection**[2] vulnerabilities in several cases. ## Mitigation The attacks outlined above rely on decoded user data being passed to the `HttpURI` class. Application should not pass decoded user data as an encoded URI to any URI class/method, including `HttpURI`. Such applications are likely to be vulnerable in other ways. The immediate solution is to upgrade to a version of the class that will fully validate the characters of the URI authority. Ultimately, Jetty will deprecate and remove support for user info in the authority per [RFC9110 Section 4.2.4](https://datatracker.ietf.org/doc/html/rfc9110#section-4.2.4). Note that the Chrome (and other browsers) parse the invalid user info section improperly as well (due to flawed WhatWG URL parsing rules that do not apply outside of a Web Browser). ## Reference [1] https://cwe.mitre.org/data/definitions/918.html [2] https://cwe.mitre.org/data/definitions/601.html |

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/?@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. ### 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) |
