-------------------------------------

             Summary: Review the possibility of using OWASP Sanitizer in FormattedServiceListWriter
                 Key: CXF-7128
                 URL: https://issues.apache.org/jira/browse/CXF-7128
             Project: CXF
          Issue Type: Improvement
          Components: Transports
            Reporter: Sergey Beryozkin
             Fix For: NeedMoreInfo


https://www.owasp.org/index.php/OWASP_Java_HTML_Sanitizer_Project project (and related projects)
offer a number of ways to protect against XSS.

Right now CXF ServletController uses BaseUrlHelper to recreate an absolute URL it listens
upon, by removing all the matrix parameters which were shown to pose a risk (CXF-6216). 

The question is: is CXF-6216 fix sufficient or some more formal approach is needed. 

My own opinion right now is that a CXF-6216 fix is good and there's no obvious need to add
another library unless a new concrete attack is discovered. 

CXF-6216 fix results in all the matrix parameters, if any, being removed. The encoding approach
will keep them in the encoded form in service URIs which will be shown to the user.
