Summary

The Apache Solr that is shipped with IBM Rational ClearQuest contains
multiple security vulnerabilities. IBM Rational ClearQuest has addressed the
applicable CVEs.

Vulnerability Details

CVEID:

CVE-2013-6407

DESCRIPTION:

Apache Solr could allow a remote authenticated attacker to obtain sensitive
information, caused by an error when parsing XML entities. By 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

CVEID:

CVE-2013-6408

DESCRIPTION:

Apache Solr could allow a remote authenticated attacker to obtain sensitive
information, caused by an error when parsing XML entities. By persuading a
victim to open a specially-crafted XML document containing external entity
references, an attacker could exploit this vulnerability to obtain sensitive
information.

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


Remediation/Fixes

The solution 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 takes 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).
