The SymmetricBinding in Apache CXF before 2.6.13 and 2.7.x before 2.7.10, when EncryptBeforeSigning is enabled and the UsernameToken policy is set to an EncryptedSupportingToken, transmits the UsernameToken in cleartext, which allows remote attackers to obtain sensitive information by sniffing the network.

The SecurityTokenService (STS) in Apache CXF before 2.6.12 and 2.7.x before 2.7.9 does not properly validate SAML tokens when caching is enabled, which allows remote attackers to gain access via an invalid SAML token.

Apache CXF before 2.6.14 and 2.7.x before 2.7.11 allows remote attackers to cause a denial of service (/tmp disk consumption) via a large invalid SOAP message.

Apache CXF before 2.6.14 and 2.7.x before 2.7.11 allows remote attackers to cause a denial of service (memory consumption) via a large request with the Content-Type set to text/html to a SOAP endpoint, which triggers an error.

Multiple denial of service flaws were found in the way StAX parser implementation of Apache CXF, an open-source web services framework, performed processing of certain XML files. If a web service application utilized the services of the StAX parser, a remote attacker could provide a specially-crafted XML file that, when processed by the application would lead to excessive system resources (CPU cycles, memory) consumption by that application.

Apache CXF 2.5.x before 2.5.10, 2.6.x before CXF 2.6.7, and 2.7.x before CXF 2.7.4 does not verify that a specified cryptographic algorithm is allowed by the WS-SecurityPolicy AlgorithmSuite definition before decrypting, which allows remote attackers to force CXF to use weaker cryptographic algorithms than intended and makes it easier to decrypt communications, aka "XML Encryption backwards compatibility attack."
