Description Pedro Sampaio 2018-10-05 15:00:38 UTC
A flaw was found in Apache tomcat. When the default servlet returned a redirect to a directory (e.g. redirecting to /foo/ when the user requested /foo) a specially crafted URL could be used to cause the redirect to be generated to any URI of the attackers choice.

Comment 1 Pedro Sampaio 2018-10-05 15:01:57 UTC
Created tomcat tracking bugs for this issue:

Affects: epel-all [bug 1636514]
Affects: fedora-all [bug 1636513]

Comment 5 Doran Moppert 2018-10-23 04:32:48 UTC
This vulnerability does not affect Tomcat 6.0.24 as Response.sendRedirect() always sends an absolute URL.

Vulnerable versions of Tomcat may not be exploitable under either the following conditions:

 - if org.apache.catalina.STRICT_SERVLET_COMPLIANCE set to true
 - if org.apache.catalina.servlets.DefaultServlet is either:
   - not deployed at all
   - only deployed with Context attribute useRelativeRedirects set to false
   - only deploted with both Context attributes mapperContextRootRedirectEnabled and mapperDirectoryRedirectEnabled are set to false
