Description

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.

Risk Scores
Base Score
3.7

The vulnerability can be exploited over the network without needing physical access. It is difficult for an attacker to exploit this vulnerability and may require special conditions. An attacker does not need any special privileges or access rights. No user interaction is needed for the attacker to exploit this vulnerability. The impact is confined to the system where the vulnerability exists. There is a low impact on the integrity of the data.

Threat Intelligence
3.4

Limited exploitation activity has been observed. Close monitoring and planned remediation are recommended.

EPSS
0.16%

The exploit probability is very low. The vulnerability is unlikely to be exploited in the next 30 days.
