persuading a victim to open a specially-crafted XML document containing
external entity references, an attacker could exploit this vulnerability to
obtain sensitive information.
CVSS Base Score: 4
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
89379 for the current score
CVSS Environmental Score*: Undefined

+---------------------------------------+-------------------------------------+

Workarounds and Mitigations

The mitigation is to take the following steps:

 1. Locate the file <CQFTS_Home>/<DBSet_UserDB>/Solr/solr/conf/solrconfig.xml
 2. Find the following two XML blocks that read

    <requestHandler name="/update/xslt"
    startup="lazy"
    class="solr.XsltUpdateRequestHandler"/>

    And

    <requestHandler name="/analysis/document"
    class="solr.DocumentAnalysisRequestHandler"
    startup="lazy"/>

 3. Either remove those two XML blocks or comment them out.
    If you wish to use comments to exclude these blocks, you may use code like
    this surrounding the blocks:

    <!--
    ...commented out block lines...
    -->

 4. Locate the file <CQFTS_Home>/<DBSet_UserDB>/Solr/typeahead/conf/
    solrconfig.xml
 5. Find the following two XML blocks that read

    <requestHandler name="/update/xslt"
    startup="lazy"
    class="solr.XsltUpdateRequestHandler"/>

    And

    <requestHandler name="/analysis/document"
    class="solr.DocumentAnalysisRequestHandler"
    startup="lazy"/>

 6. Either remove those two XML blocks or comment them out.
    If you wish to use comments to exclude these blocks, you may use code like
    this surrounding the blocks:

    <!--
    ...commented out block lines...
    -->

 7. Using cqtsadmin.pl script, run the commands --stop_fts_was_profile and
    --start_fts_was_profile as documented here https://www.ibm.com/support/
    knowledgecenter/en/SSSH5A_9.0.1/com.ibm.rational.clearquest.cli.doc/topics/
    r_cqtsadmin_pl.htm to restart Solr so the changes to the solrconfig.xml
    files take effect.

+---------------------------------------------------------------------------------------+
|Attention: The above steps must be done for all instances of ClearQuest                |
|Full-Text Search that you have deployed in your environment. (For each                 |
|Full-Text Search enabled User Database).                                               |
