Descriptions

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.

El (1) UpdateRequestHandler para XSLT o (2) XPathEntityProcessor en Apache Solr anteriores a 4.1 permite a atacantes remotos tener un impacto no especificado a través de datos XML que contengan declaraciones de entidad externa en conjunción con referencia a una entidad, relacionado con un problema de XML External Entity (XXE), vectores diferentes a CVE-2013-6407.

Red Hat JBoss Web Framework Kit combines popular open source web frameworks into a single solution for Java applications. The Apache Solr component is an open-source search server based on the Lucene Java search library. It was found that the SolrResourceLoader class in Apache Solr allowed loading of resources via absolute paths, or relative paths which were not sanitized for directory traversal. Some Solr components expose REST interfaces which load resources via SolrResourceLoader, using paths identified by REST parameters. A remote attacker could use this flaw to load arbitrary local files on the server via SolrResourceLoader, potentially resulting in information disclosure or remote code execution.
