Descriptions

Multiple XML external entity (XXE) vulnerabilities in the (1) Dom4JDriver, (2) DomDriver, (3) JDomDriver, (4) JDom2Driver, (5) SjsxpDriver, (6) StandardStaxDriver, and (7) WstxDriver drivers in XStream before 1.4.9 allow remote attackers to read arbitrary files via a crafted XML document.

Múltiples vulnerabilidades de entidad externa (XXE) en (1) Dom4JDriver, (2) DomDriver, (3) JDom Driver, (4) JDom2Driver, (5) SjsxpDriver, (6) StandardStaxDriver y (7) WstxDriver drivers en XStream en versiones anteriores a 1.4.9 permiten a atacantes remotos leer archivos arbitrarios a través de un documento XML manipulado.

It was found that several XML parsers used by XStream had default settings that would expand entity references. A remote, unauthenticated attacker could use this flaw to read files accessible to the user running the application server, and potentially perform other more advanced XXE attacks.
