For Eclipse Jetty versions 9.4.37-9.4.42, 10.0.1-10.0.5 & 11.0.1-11.0.5, URIs can be crafted using some encoded characters to access the content of the WEB-INF directory and/or bypass some security constraints. This is a variation of the vulnerability reported in CVE-2021-28164/GHSA-v7ff-8wcx-gmc5.

GHSA-vjv5-gp2w-65vm — Encoded URIs can access WEB-INF directory in Eclipse Jetty

Affected: Maven: org.eclipse.jetty:jetty-webapp

### Description URIs can be crafted using some encoded characters to access the content of the `WEB-INF` directory and/or bypass some security constraints. This is a variation of the vulnerability reported in [CVE-2021-28164](https://nvd.nist.gov/vuln/detail/CVE-2021-28164)/[GHSA-v7ff-8wcx-gmc5](https://github.com/eclipse/jetty.project/security/advisories/GHSA-v7ff-8wcx-gmc5).

### Impact The default compliance mode allows requests with URIs that contain a %u002e segment to access protected resources within the WEB-INF directory. For example, a request to `/%u002e/WEB-INF/web.xml` can retrieve the web.xml file. This can reveal sensitive information regarding the implementation of a web application. Similarly, an encoded null character can prevent correct normalization so that /.%00/WEB-INF/web.xml cal also retrieve the web.xml file.

### Workarounds Some Jetty [rewrite rules](https://www.eclipse.org/jetty/documentation/jetty-9/index.html#rewrite-handler) can be deployed to rewrite any request containing encoded dot segments or null characters in the raw request URI, to a known not found resource: ```xml <Call name="addRule"> <Arg> <New class="org.eclipse.jetty.rewrite.handler.RewriteRegexRule"> <Set name="regex">.*/(?:\.+/)+.*</Set> <Set name="replacement">/WEB-INF/Not-Found</Set> </New> </Arg> </Call> <Call name="addRule"> <Arg> <New class="org.eclipse.jetty.rewrite.handler.ValidUrlRule"/> </Arg> </Call> ```
