Versions of Apache Solr prior to 5.0 are affected by multiple vulnerabilities :
- A XXE injection flaw exists in ‘UpdateRequestHandler’ that is triggered during the parsing of XML data. The issue is due to an incorrectly configured XML parser accepting XML external entities from an untrusted source. By sending specially crafted XML data, a remote attacker can gain access to arbitrary files. (CVE-2012-6612, CVE-2013-6407)
- A XXE injection flaw in ‘DocumentAnalysisRequestHandler’ exists that is triggered during the parsing of XML data. The issue is due to an incorrectly configured XML parser accepting XML external entities from an untrusted source. By sending specially crafted XML data, a remote attacker can gain access to arbitrary files. (CVE-2013-6408)
