Security Vulnerability in the Sun Ray Server Software Authentication Manager May Allow a Denial of Service (DoS)

1. Impact

A security vulnerability in the Sun Ray Server Software Authentication Manager may allow a remote unprivileged user to cause a Denial of Service (DoS) to Sun Ray services or to run arbitrary code with root privileges.

2. Contributing Factors

This issue can occur in the following releases:

SPARC Platform
  • Sun Ray Server Software 4.0 (for Solaris 10) without patch 127553-07
  • Sun Ray Server Software 4.1 (for Solaris 10) without patch 139548-03
x86 Platform
  • Sun Ray Server Software 4.0 (for Solaris 10) without patch 127554-07
  • Sun Ray Server Software 4.1 (for Solaris 10) without patch 139549-03
Linux
  • Sun Ray Server Software 4.0 (for RHEL AS 4, SLES 9) without patch 127555-07
  • Sun Ray Server Software 4.1 (for RHEL 5, SLES 10) without patch 139550-03
To determine if Authentication Manager is running, the following command can be run:
$ ps -ef | grep utauth
root  3910  3909  0 Jul 31 ? 434:01 /etc/opt/SUNWut/jre/bin/java -client auth.utauthd.utauthd
If no Java process with '-client auth.utauthd.utauthd' parameters is listed, then Sun Ray Authentication Manager is not running.

Alternatively, If utauthd(1M) has crashed, running the utgstatus(1M) tool will report an error:
$ /opt/SUNWut/sbin/utgstatus
Error: Could not get gstatus information from server <hostname>
Sun Ray Server Software 4.2 is not impacted by this issue. To determine the version of the Sun Ray Server Software on a Solaris system, the following command can be run:
$ /usr/bin/pkgparam SUNWuto VERSION
4.2_77,REV=2009.10.19.17.01
To determine the version of the Sun Ray Server Software on a Linux system, the following command can be run:
$ /bin/rpm -q SUNWuto
SUNWuto-4.2-77
3. Symptoms

Sun Ray DTUs will show a 26D OSD icon if the Sun Ray Authentication Manager is no longer running.

There are no reliable symptoms which would indicate that this issue has been exploited to execute arbitrary code without crashing the Sun Ray Authentication Manager.

Commands such as the following can be used to determine if the Sun Ray Authentication Manager is no longer running on the server:
$ ps -ef | grep utauth
root  3910  3909  0 Jul 31 ? 434:01 /etc/opt/SUNWut/jre/bin/java -client auth.utauthd.utauthd
If no java process with '-client auth.utauthd.utauthd' parameters is listed, then the Authentication Manager is not running.

Alternatively, If utauthd(1M) has crashed, running the utgstatus(1M) tool will report an error:
$ /opt/SUNWut/sbin/utgstatus
Error: Could not get gstatus information from server <hostname>
4. Workaround

There is no workaround for this issue. Please see the Resolution section below.
