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).

Affected Versions
Applying the fix
8.0.0.x
8.0.1.x
9.0.0.x
9.0.1.x
Apply the above fix directly to your ClearQuest.
For 7.0, 7.1 and earlier releases, IBM recommends upgrading to a fixed, supported version/release/platform of the product.

When future versions of ClearQuest ship with the fix, only existing deployments needs to use this correction, all new deployments of CQ FTS instances will not have this vulnerability. Work tracking this is in [PSIRT 1353] remove 2 Solr request handlers: requestHandler and requestHandler (65206) and currently planned for 2018A (subject to change). --david.sampson@hcl.com per George Aroush.
