"value":"** UNSUPPPORTED WHEN ASSIGNED ** An XML External Entity (XXE) vulnerability exists in the gateway component of WSO2 API Manager due to insufficient validation of XML input in crafted URL paths. User-supplied XML is parsed without appropriate restrictions, enabling external entity resolution.\n\n\nThis vulnerability can be exploited by an unauthenticated remote attacker to read files from the server\u2019s filesystem or perform denial-of-service (DoS) attacks.\n\n\n\n * \nOn systems running JDK 7 or early JDK 8, full file contents may be exposed.\n\n\n\n\n * \nOn later versions of JDK 8 and newer, only the first line of a file may be read, due to improvements in XML parser behavior.\n\n\n\n\n * \nDoS attacks such as \"Billion Laughs\" payloads can cause service disruption."
