1 CVE-2017-12629 611 Exec Code 2017-10-14 2017-11-07
7.5
None Remote Low Not required Partial Partial Partial
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.
2 CVE-2017-9803 287 2017-09-18 2017-10-04
6.0
None Remote Medium Single system Partial Partial Partial
Solr's Kerberos plugin can be configured to use delegation tokens, which allows an application to reuse the authentication of an end-user or another application. There are two issues with this functionality (when using SecurityAwareZkACLProvider type of ACL provider e.g. SaslZkACLProvider). Firstly, access to the security configuration can be leaked to users other than the solr super user. Secondly, malicious users can exploit this leaked configuration for privilege escalation to further expose/modify private data and/or disrupt operations in the Solr cluster. The vulnerability is fixed from Solr 6.6.1 onwards.

Apache Solr uses a PKI based mechanism to secure inter-node communication when security is enabled. It is possible to create a specially crafted node name that does not exist as part of the cluster and point it to a malicious node. This can trick the nodes in cluster to believe that the malicious node is a member of the cluster. So, if Solr users have enabled BasicAuth authentication mechanism using the BasicAuthPlugin or if the user has implemented a custom Authentication plugin, which does not implement either "HttpClientInterceptorPlugin" or "HttpClientBuilderPlugin", his/her servers are vulnerable to this attack. Users who only use SSL without basic authentication or those who use Kerberos are not affected.
4 CVE-2017-3163 22 Dir. Trav. 2017-08-30 2017-09-11
5.0
None Remote Low Not required Partial None None
When using the Index Replication feature, Apache Solr nodes can pull index files from a master/leader node using an HTTP API which accepts a file name. However, Solr before 5.5.4 and 6.x before 6.4.1 did not validate the file name, hence it was possible to craft a special request involving path traversal, leaving any file readable to the Solr server process exposed. Solr servers protected and restricted by firewall rules and/or authentication would not be at risk since only trusted clients and users would gain direct HTTP access.
5 CVE-2015-8797 79 XSS 2016-02-14 2016-02-22
4.3
None Remote Medium Not required None Partial None
Cross-site scripting (XSS) vulnerability in webapp/web/js/scripts/plugins.js in the stats page in the Admin UI in Apache Solr before 5.3.1 allows remote attackers to inject arbitrary web script or HTML via the entry parameter to a plugins/cache URI.
6 CVE-2015-8796 79 XSS 2016-02-14 2017-07-27
4.3
None Remote Medium Not required None Partial None
Cross-site scripting (XSS) vulnerability in webapp/web/js/scripts/schema-browser.js in the Admin UI in Apache Solr before 5.3 allows remote attackers to inject arbitrary web script or HTML via a crafted schema-browse URL.
7 CVE-2015-8795 79 XSS 2016-02-14 2016-02-22
4.3
None Remote Medium Not required None Partial None
Multiple cross-site scripting (XSS) vulnerabilities in the Admin UI in Apache Solr before 5.1 allow remote attackers to inject arbitrary web script or HTML via crafted fields that are mishandled during the rendering of the (1) Analysis page, related to webapp/web/js/scripts/analysis.js or (2) Schema-Browser page, related to webapp/web/js/scripts/schema-browser.js.
8 CVE-2014-3628 79 XSS 2015-01-06 2015-01-06
4.3
None Remote Medium Not required None Partial None
Cross-site scripting (XSS) vulnerability in the Admin UI Plugin / Stats page in Apache Solr 4.x before 4.10.3 allows remote attackers to inject arbitrary web script or HTML via the fieldvaluecache object.
9 CVE-2013-6408 2013-12-07 2014-07-17
6.4
None Remote Low Not required Partial None Partial
The DocumentAnalysisRequestHandler in Apache Solr before 4.3.1 does not properly use the EmptyEntityResolver, which allows remote attackers to have an unspecified impact via XML data containing an external entity declaration in conjunction with an entity reference, related to an XML External Entity (XXE) issue. NOTE: this vulnerability exists because of an incomplete fix for CVE-2013-6407.
10 CVE-2013-6407 2013-12-07 2014-07-17
6.4
None Remote Low Not required Partial None Partial
The UpdateRequestHandler for XML in Apache Solr before 4.1 allows remote attackers to have an unspecified impact via XML data containing an external entity declaration in conjunction with an entity reference, related to an XML External Entity (XXE) issue.
11 CVE-2013-6397 22 Dir. Trav. 2013-12-07 2015-10-23
4.3
None Remote Medium Not required Partial None None
Directory traversal vulnerability in SolrResourceLoader in Apache Solr before 4.6 allows remote attackers to read arbitrary files via a .. (dot dot) or full pathname in the tr parameter to solr/select/, when the response writer (wt parameter) is set to XSLT. NOTE: this can be leveraged using a separate XXE (XML eXternal Entity) vulnerability to allow access to files across restricted network boundaries.
12 CVE-2012-6612 2013-12-07 2014-03-08
7.5

The (1) UpdateRequestHandler for XSLT or (2) XPathEntityProcessor in Apache Solr before 4.1 allows remote attackers to have an unspecified impact via XML data containing an external entity declaration in conjunction with an entity reference, related to an XML External Entity (XXE) issue, different vectors than CVE-2013-6407.
