Sun Ray Server Software 4.0
Date of Resolved Release
Security Vulnerability in Sun Ray Server Software May Compromise the Sun Ray Administration Password
A security vulnerability in Sun Ray Server Software may allow remote unprivileged users to gain access to the Sun Ray administration password, which in turn would allow unauthorized remote access to the Sun Ray Data Store and unauthorized access to the Sun Ray Administration GUI as the built-in 'admin' user.
2. Contributing Factors
This issue can occur in the following releases:
1. Sun Ray Server Software 3.1 without patch 120879/120880/120881, Sun Ray Server Software 3.0 and earlier releases are not affected.
To determine the version of Sun Ray Server software in use, the following command can be run:
$ /opt/SUNWut/lib/utprodinfo -p SUNWuto VERSION
2. Servers that are configured as secondary servers in a replication group are usually affected. This occurs the first time replication is configured using the utreplica(1M) tool after the server was configured using utconfig(1M).
To determine if a Sun Ray server is configured as secondary server in a replication group, the utreplica(1M) command line tool can be used:
$ /opt/SUNWut/sbin/utreplica -l
testserver2 is a secondary server3. To determine if a system may be affected, the following commands can be run as 'root" user:
$ sed -n '/SUNWut begin/,/SUNWut end/ s/.*access to.*"\(.*\)".*/\1/p' /etc/opt/SUNWut/srds/current/utdsd.acl.conf | uniq | wc -lIf the output of this command is "1", the system is not affected.
If the output is "2" the system may be affected, and the following command can be run as root to further confirm this:
$ sed -n 's/.*utname=\([^,]*\),.*/\1/p' /etc/opt/SUNWut/srds/current/utdsd.acl.conf | uniq | wc -lIf the output of this command is "2", the system is most likely affected.
There are no predictable symptoms that would indicate the described issue has been exploited.
If a system is configured as a secondary replication server, a safe configuration can be created by temporarily unconfiguring and immediately restoring the replication state using the utreplica(1M) command with the '-u' and '-s' options. After this change has been applied to all secondary servers in the replication group, use the utpw(1M) command or the Sun Ray web administration GUI to change the Sun Ray administration password on all servers in the replication group.
Note: If uttscadm(1M) is run to configure Sun Ray Windows Connector after application of this workaround, the workaround needs to be reapplied. If utconfig(1M) is run to recreate the configuration of Sun Ray Server Software and the server is subsequently again converted to a secondary replication server, the workaround needs to be reapplied.
This issue is addressed in the following releases:
