Sun(sm) Alert Notification
* Sun Alert ID: 101918
* Synopsis: Security Vulnerability in the Logging Output of Sun Java
System Access Manager
* Category: Security
* Product: Sun Java System Access Manager 2004Q2, Sun Java System
Access Manager 6 2005Q1, Sun Java System Identity Server 6.1
* BugIDs: 6269826
* Avoidance: Patch, Workaround
* State: Workaround
* Date Released: 10-Jul-2007
* Date Closed:
* Date Modified:
1. Impact
When the debug level within Sun Java System Access Manager (formerly
Sun Java System Identity Server) is set to "message," login passwords
may be logged in plain text and are therefore readable by local
unprivileged users. This would allow that user to gain unauthorized
access to user identities which are managed by Sun Java System Access
Manager.
2. Contributing Factors
This issue can occur in the following releases:
SPARC Platform
* Sun One Identity Server 6.1 for Solaris 8 and 9 without patch
117586-16
* Sun Java System Access Manager 6.2 (2004Q2) for Solaris 8 and 9
without patch 115766-09
* Sun Java System Access Manager 6 (2005Q1) for Solaris 9 without
patches 119465-02 and 119466-02
* Sun Java System Access Manager 6 (2005Q1) for Solaris 10 without
patch 119465-09
x86 Platform
* Sun One Identity Server 6.1 for Solaris 8 and 9
* Sun Java System Access Manager 6.2 (2004Q2) for Solaris 8 and 9
without patch 120091-09
* Sun Java System Access Manager 6 (2005Q1) for Solaris 9 without
patches 119465-02 and 119467-02
* Sun Java System Access Manager 6 (2005Q1) for Solaris 10 without
patch 119467-09
Linux
* Sun Java System Acess Manager 6.2 (2004Q2) without patch
119409-09
* Sun Java System Access Manager 6 (2005Q1) for RHEL2.1 without
patch 119502-02
Note: Patch 119465-02 is a "generic" patch, applicable to both
SPARC and x86 platforms.
Systems are only impacted when the "com.iplanet.services.debug.level"
property is set to "message" in the
"/etc/opt/SUNWam/config/AMConfig.properties" file (this flag is
usually set to help with debugging).
The debug level can be determined by looking at the
"AMConfig.properties" file for an entry similar to the following
(example):
com.iplanet.services.debug.level=message
To determine the version of Sun Java System Access Manager on a
system, the following command can be run:
$ /opt/SUNWam/bin/amadmin -n
or for Identity server:
$ /opt/SUNWam/bin/amserver -n
Sun Java System Identity Server version 2004Q2
3. Symptoms
Plain text passwords are shown in the "/var/opt/SUNWam/debug/amAuth"
debug file. The following is a sample output of the "amAuth" debug
file after login, where "Login.Token2=testpassword" appears in plain
text:
# grep -i token2 amAuth | more
LoginStateReturning.. hash :{channelName=Login, module=Membership, Login.To
ken2=
password, Login=Login, Login.Token1=user1}
LoginStateReturning.. hash :{channelName=Login, module=Membership, Login.To
ken2=
testpassword, Login=Login, Login.Token1=testuser}
LoginStateReturning.. hash :{channelName=Login, module=Membership, Login.To
ken2=
testpassword, Login=Login, Login.Token1=testuser}
4. Relief/Workaround
To work around the described issue, do not use the "message" debug
mode. Instead, set the debug level in the
"/etc/opt/SUNWam/config/AMConfig.properties" file to "error", as in
the following example:
com.iplanet.services.debug.level=error
5. Resolution
This issue is addressed in the following releases:
SPARC Platform
* Sun One Identity Server 6.1 (for Solaris 8 and 9) with patch
117586-16 or later
* Sun Java System Access Manager 6.2 (2004Q2) for Solaris 8 and 9
with patch 115766-09 or later
* Sun Java System Access Manager 6 (2005Q1) for Solaris 9 with
patches 119465-02 or later and 119466-02 or later
* Sun Java System Access Manager 6 (2005Q1) for Solaris 10 with
patch 119465-09 or later
x86 Platform
* Sun Java System Access Manager 6.2 (2004Q2) for Solaris 8 and 9
with patch 120091-09 or later
* Sun Java System Access Manager 6 (2005Q1) for Solaris 9 with
patches 119465-02 or later and 119467-02 or later
* Sun Java System Access Manager 6 2005Q1) for Solaris 10 with patch
119467-09 or later
Linux
* Sun Java System Acess Manager 6.2 (2004Q2) with patch
119409-09 or later
* Sun Java System Access Manager 6 2005Q1 (for RHEL2.1) with patch
119502-02 or later
Notes:
1. Both patches listed for Sun Java System Access Manager 6 (2005Q1)
for Solaris 9 on the SPARC and x86 platforms must be installed to
resolve this issue.
2. Patch 119465-02 is a "generic" patch, applicable to both SPARC
and x86 platforms.
3. Sun One Identity Server 6.1 for Solaris 8 and 9 on x86 requires an
upgrade to Sun Java System Access Manager 6.2 to resolve this
issue.
A final resolution is pending completion.
