  • Attack Protection Against XML Encryption Vulnerability
    Publication number: 20140165194
    Abstract: Protection against an attack which exploits an eXtensible Markup Language (XML) Encryption vulnerability includes receiving a ciphertext request utilizing an EncryptedKey element and detecting either a failure to decrypt the cipher value in the EncryptedData element or a failure to parse the resulting decrypted XML. Upon detecting the failure, a count of failures associated with the EncryptedKey element is incremented, and when the count exceeds a threshold number of failures, subsequent usage of the EncryptedKey element and delivery of the request to an application service are prevented. Optionally, a rejection message is returned to the requester.
