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 CVSS Vector: (AV:N/AC:L/Au:S/C:P/I:N/A:N) 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. CVSS Base Score: 4 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/89380 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (AV:N/AC:L/Au:S/C:P/I:N/A:N) Affected Products and Versions IBM Rational ClearQuest, versions 8.0, 8.0.1, 9.0 and 9.0.1 in the following component: o ClearQuest Full-Text Search. o +-------------------------------------+-----------------------------------+ | ClearQuest version | Status | +-------------------------------------+-----------------------------------+ | 9.0.1, 9.0.1.1 | Affected | +-------------------------------------+-----------------------------------+ | 9.0 through 9.0.0.5 | Affected | +-------------------------------------+-----------------------------------+ | 8.0.1 through 8.0.1.15 | Affected | +-------------------------------------+-----------------------------------+ | 8.0 through 8.0.0.21 | Affected | +-------------------------------------+-----------------------------------+ 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). +-------------------+---------------------------------------------------------+ | Affected Versions | Applying the fix | +-------------------+---------------------------------------------------------+ |8.0.0.x |Apply the above fix directly to your ClearQuest. | |8.0.1.x | | |9.0.0.x | | |9.0.1.x | | +-------------------+---------------------------------------------------------+ For 7.0, 7.1 and earlier releases, IBM recommends upgrading to a fixed, supported version/release/platform of the product.
