Solution Type: Sun Alert
Solution 201538 : Sun Java System Access Manager Does Not Securely
Process XSLT Stylesheets contained in XML Signatures contained in XML
Signatures
Bug ID: 6547061
Product
Sun Java System Access Manager 6 2005Q1
Sun Java System Access Manager 7.1
Sun Java System Identity Server 6.1
Sun Java System Identity Server 6.2
Sun Java System Access Manager 7 2005Q4
Date of Resolved Release: 26-Jun-2008
SA Document Body
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.
2. Contributing Factors
This issue can occur in the following releases:
SPARC Platform:
* Sun Java System Access Manager 7.1 (for Solaris 8, 9 and 10)
without patch 126356-01
* Sun Java System Access Manager 7 2005Q4 (for Solaris 8, 9 and 10)
without patch 120954-06
* Sun Java System Access Manager 6.3 2005Q1 (for Solaris 8, 9 and
10) without patch 119465-12
* Sun Java System Identity Server 6.2 (for Solaris 8 and 9) without
patch 115766-15
* Sun Java System Identity Server 6.1 (for Solaris 8 and 9) without
patch 117586-22
x86 Platform:
* Sun Java System Access Manager 7.1 (for Solaris 8, 9 and 10)
without patch 126357-01
* Sun Java System Access Manager 7 2005Q4 (for Solaris 9 and 10)
without patch 120955-06
* Sun Java System Access Manager 6.3 2005Q1 (for Solaris 8, 9 and
10) without patch 119465-12

* Sun Java System Access Manager 7 2005Q4 without patch 120956-06
* Sun Java System Access Manager 6.3 2005Q1 without patch 119502-12
Windows:
* Sun Java System Access Manager 7.1 without patch 126359-01
* Sun Java System Access Manager 7 2005Q4 without patch 124296-06
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
