Description
The WS-Security 1.0 receive pipeline validates the
SignatureMethod of an incoming ds:SignedInfo against the configured SecurityAlgorithmSuite but fails to validate the DigestMethod declared on each ds:Reference. This allows a sender to use a rejected digest algorithm, such as SHA-1, while the message is still accepted because the signature is verified using a method that permits SHA-1 digests.Recommendations
Update to version 1.8.1.
Update to version 1.9.1.
