  "details" : [ "A flaw was found in Apache MINA. A remote attacker could exploit a vulnerability in the `AbstractIoBuffer.resolveClass()` method, which failed to properly validate class names for static classes or primitive types. This bypasses the intended security control, known as a classname allowlist, allowing an attacker to execute arbitrary code on systems running applications that use Apache MINA and call `IoBuffer.getObject()`. This could lead to a complete compromise of the affected system." ],
