7.1.0- Upgrade org.apache.solr:solr-core to this version or later
Description
Remote code execution occurs in Apache Solr before versions 5.5.5, 6.6.2 and 7.1.0 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 versions
Maven
| Package | Vulnerable | Fixed in |
|---|---|---|
| org.apache.solr:solr-core | >= 7.0.0, < 7.1.0 |
7.1.0 |
| org.apache.solr:solr-core | >= 6.0.0, < 6.6.2 |
6.6.2 |
| org.apache.solr:solr-core | >= 5.5.0, < 5.5.5 |
5.5.5 |
How to fix
Move to the fixed version or later with your package manager, update the lockfile, and run your tests. If the package only arrives through another dependency, upgrade that dependency first. If none of its releases pulls a fixed version yet, force the version with your package manager's override.

Weakness
CWE-611: Improper Restriction of XML External Entity Reference
The product processes an XML document that can contain XML entities with URIs that resolve to documents outside of the intended sphere of control, causing the product to embed incorrect documents into its output.
How to prevent it
- Implementation, System Configuration: Many XML parsers and validators can be configured to disable external entity expansion.
