## Affected

- Eclipse Foundation Eclipse Mojarra: from 2.3, through 5.0

## Description

In Eclipse Mojarra versions 2.3 and following, URL handing in `DefaultFaceletFactory` does not properly sanitize and/or block remote URLs, allowing an attacker to specify a URL to a remote Facelet which will be included and processed as part of the normal request, with the privileges of the target server. This could allow access to restricted files such as `WEB-INF/web.xml` or `/etc/passwd`.
