Descriptions

DocumentProvider in RESTEasy 2.3.7 and 3.0.9 does not configure the (1) external-general-entities or (2) external-parameter-entities features, which allows remote attackers to conduct XML external entity (XXE) attacks via unspecified vectors.

DocumentProvider en RESTEasy 2.3.7 y 3.0.9 no configura las caracteristicas (1) external-general-entities o (2) external-parameter-entities, lo que permite a atacantes remotos realizar ataques de entidad externa XML (XXE) a través de vectores no especificados.

It was found that the RESTEasy DocumentProvider did not set the external-parameter-entities and external-general-entities features appropriately, thus allowing external entity expansion. A remote attacker able to send XML requests to a RESTEasy endpoint could use this flaw to read files accessible to the user running the application server, and potentially perform other more advanced XML eXternal Entity (XXE) attacks.
