XML External Entity attack, or simplyXXE attack, is a type of attack against an application that parsesXMLinput. This attack occurs when XML input containing a reference to an external entity is processed by a weakly configured XML parser. This attack may lead to the disclosure of confidential data,DoS attacks,server-s... | https://en.wikipedia.org/wiki/XML_external_entity_attack |
