CVE-2016-3674

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.

It was discovered that XStream incorrectly handled parsing of certain crafted XML documents. A remote attacker could possibly use this issue to read arbitrary files. Zhihong Tian and Hui Lu found that XStream was vulnerable to remote code execution. A remote attacker could run arbitrary shell commands by manipulating the processed input stream. It was discovered that XStream was vulnerable to server-side forgery attacks. A remote attacker could request data from internal resources that are not publicly available only by manipulating the processed input stream.
