APAR status

  • Closed as program error.

Error description

  • When WS-Security verifies an XML Digital Signature that uses the
    enveloped-signature transform, a 'Digest value mismatch' error
    may occur.

    *                  WS-Security JAX-WS applications             *

    * PROBLEM DESCRIPTION: 'Digest value mismatch' error may       *
    *                      occur when using the                    *

    ****************************************************************
    * RECOMMENDATION:  Install an fix pack that contains this      *
    *                  APAR.                                       *
    ****************************************************************
    When WS-Security verifies an XML Digital Signature that uses
    the http://www.w3.org/2000/09/xmldsig#enveloped-signature
    transform algorithm and the signed element has attributes with
    a namespace prefix, a 'Digest value mismatch' error similar
    to the following may occur:
    SAML Assertion signature is verified.Core validity=false
    Signed info validity=true Signed info
    message='null'(validity=false message='Digest value mismatch:
    calculated: KCuNwlUAk5+G2PYb8fZ+Y1hTMtw='
    uri='#Assertion-1234' type='null')
    

Problem conclusion

  • If an element to be signed contains an attribute with a
    namespace prefix the WS-Security is improperly canonicalizing
    the element before calculating the digest value.
    
    The WS-Security runtime is updated to properly handle element
    attributes with namespace prefixes.
    
    If the application of this APAR is causing compatibility
    problems in a cell that has application servers at different
    fixpack levels, you can return the runtime to the previous
    behavior by doing the following:
    
    Set the following JVM system property:
    
    com.ibm.wsspi.wssecurity.dsig.enableEnvelopedSignatureProperty=t
    rue
    
    Set the following WS-Security custom property in the Inbound,
    Outbound, or Inbound and Oubound custom properties in the
    WS-Security policy set bindings:
    
    com.ibm.wsspi.wssecurity.dsig.oldEnvelopedSignature=true
    
    If you are using the SAMLTokenFactory to create a SAML token,
    set the JVM system property and set the property shown above
    in the SAMLIssuerConfig.properties file.
    
    The fix for this APAR is currently targeted for inclusion in
    fix packs 7.0.0.23 and 8.0.0.4.  Please refer to the
    Recommended Updates page for delivery information:
