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.

Solr versions 1.3.0 to 1.4.1, 3.1.0 to 3.6.2 and 4.0.0 to 4.10.4 are vulnerable to an XML resource consumption attack (a.k.a. Lol Bomb) via it’s update handler.?By leveraging XML DOCTYPE and ENTITY type elements, the attacker can create a pattern that will expand when the server parses the XML causing OOMs.

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.

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.

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.

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.
