Sun Java System Access Manager Does Not Securely Process XSLT Stylesheets contained in XML Signatures

1. Impact

The Sun Java System Access Manager may not securely process XSLT stylesheets which are contained inside XSLT Transforms in XML Signatures.

A remote user who is able to create such an XML Signature which is viewed locally with Access Manager may be able to execute arbitrary code with the privileges of the Access Manager application. Access Manager is run by a web container application, such as the Sun Java System Application Server, and thus the privileges of Access Manager are the same as the configured web container application.

Sun acknowledges with thanks, Brad Hill of iSEC Partners for bringing this issue to our attention.

Note: With respect to Access Manager functionality, this issue only affects verification of XML signing, so if a user is not using XML signing in Access Manager, there is no impact.

To determine if XML signing is enabled for Access Manager, do the following:

  1. Login to the Access Manager console
  2. Click on the "Configuration" tab for Access Manager 7.x or the "Service Configuration" tab for Access Manager 6.x
  3. Select service: "SAML"

If any of the three check boxes labeled "Sign SAML Request", "Sign SAML Response" or "Sign SAML Assertion" is checked, the XML signing functionality is in use.

To determine the version of Access Manager on a Solaris system, the following command can be run:

    % pkginfo -l SUNWamsvc
    PKGINST:  SUNWamsvc
  NAME:  Sun Java System Access Manager Services
  CATEGORY:  application
  ARCH:  all
  VERSION:  7.0,REV=05.08.10.09.17

To determine the version of Sun Java System Access Manager on other systems, the following command can be run (as "root" user):

    # <access-manager-install-dir>/bin/amadmin --version
    Sun Java System Access Manager 7 2005Q4

3. Symptoms
