What the vendors declare (VEX)

Official vendor statements in CSAF/VEX format: whether their product is affected, already fixed, or ruled out — and why. These are the vendor's assertions, not Vexday's judgment.

Affected

2 products (5 components)

Red Hat Enterprise Linux 6 · Red Hat JBoss Data Grid 7

workaround: Until fixes are available, all Solr users are advised to restart their Solr instances with the system parameter `-Ddisable.configEdit=true`. This will disallow any changes to be made to configurations via the Config API…

Fixed

14 products (460 components)

Red Hat JBoss Enterprise Application Platform 7.0 for RHEL 6 Server · Red Hat JBoss Enterprise Application Platform 7.0 for RHEL 7 Server · Red Hat Software Collections for Red Hat Enterprise Linux Server (v. 6) · Red Hat Software Collections for Red Hat Enterprise Linux Server (v. 7) · Red Hat Software Collections for Red Hat Enterprise Linux Server EUS (v. 6.7) · and others 9

Remote code execution occurs in Apache Solr before 7.1 with Apache Lucene before 7.1 by exploiting XXE in conjunction with use of a Config API add-listener command to reach the RunExecutableListener class. Elasticsearch, although it uses Lucene, is NOT vulnerable to this. Note that the XML external entity expansion vulnerability occurs in the XML Query Parser which is available, by default, for any query request with parameters deftype=xmlparser and can be exploited to upload malicious data to the /upload request handler or as Blind XXE using ftp wrapper in order to read arbitrary local files from the Solr server. Note also that the second vulnerability relates to remote code execution using the RunExecutableListener available on all affected versions of Solr.

Affected products

n/a · Apache Solr before 7.1 with Apache Lucene before 7.1
