Security bulletin
Patch available for ColdFusion MX 7 local privilege escalation
Release date: October 10, 2006
Vulnerability identifier: APSB06-17
CVE number: CVE-2006-3978
Platform: All Platforms
Affected software versions
ColdFusion MX 7, ColdFusion MX 7.0.1, and ColdFusion MX 7.0.2
Summary
A potential vulnerability in a third party library could allow a
malicious local user to execute arbitrary code with the privilege
level of the local SYSTEM. A malicious user must first be able to run
code locally on the server to take advantage of the vulnerability.
Solution
Adobe recommends ColdFusion users apply the following update using the
installation instructions below. Alternatively, instructions for
disabling the library are available below under the heading Disabling
the Verity library.
Windows:
1. Stop all ColdFusion services.
2. Make a backup of your existing verity directory cfroot\verity by
copying cfroot\verity to cfroot\verity_backup:
+ Open a DOS window
+ enter xcopy /S c:\CfusionMX7\verity
c:\CfusionMX7\verity_backup and hit return
3. Unzip verity_security_update_windows.zip into cfroot\verity.
Make sure to unzip using directory names. Select 'Use folder
names' when using winzip or use similar options with other zip
utilities. Allow all existing files to be overwritten.
4. Restart all ColdFusion services.
Note cfroot by default is C:\CFusionMX7 for the server version.
But, in a JRun or J2EE installation verity is installed into a
separate directory of your choosing. That directory should be used
in place of cfroot.
Uninstall instructions for patch:
1. Stop all ColdFusion services.
2. Delete cfroot\verity.
3. Rename cfroot\verity_backup to cfroot\verity.
Linux and Solaris:
1. Stop all ColdFusion services.
2. Make a backup of your existing verity directory cfroot\verity by
copying cfroot\verity to cfroot\verity_backup. For example run cp
-fR /opt/coldfusionmx7/verity /opt/coldfusionmx7/verity_backup.
3. Copy the archive file to cfroot/verity.
4. Unzip and untar the update archive (Linux or Solaris) into
cfroot/verity:
verity_security_update_solaris.tar.gz
verity_security_update_linux.tar.gz
5. All executable files should have permissions of 755. Text files
should have permissions of 444.
6. Restart ColdFusion.
Uninstall instructions for patch:
1. Stop all ColdFusion services
2. Delete cfroot\verity
3. Rename/move cfroot\verity_backup to cfroot\verity
Disabling the Verity Library:
The ColdFusion MX 7 J2EE requires a separate installation of the
Verity search engine. ColdFusion MX 7 J2EE users should simply not
install it or uninstall it, if it is already installed.
Windows:
Open the services msc applet and stop, "ColdFusion MX 7 Search
Server". Set the service to manual or disabled.
Users can also run cfmx_root\verity\verity-uninstall.bat to remove the
configuration.
Linux:
Run cfmx_root/bin/cfmx7search stop.
Remove cfmx7search from etc/rc.d/init.d, if server was configured to
start Verity upon boot.
Users can run cfmx_root/verity/verity_uninstall.sh to remove the
Verity configuration.
Solaris:
Run cfmx_root/bin/cfmx7search stop.
Remove any startup script for cfmx7search, if server was configured to
start Verity upon boot.
Users can run cfmx_root/verity/verity_uninstall.sh to remove the
Verity configuration.
Severity rating
Adobe categorizes this as an important issue and recommends
affected users patch their installations.
Details
Multiple input validation errors exist in a third party service
installed with ColdFusion. By default, the service runs with the
privilege level of the local SYSTEM account. By issuing specially
crafted commands within the client software for the third-party
library, a local user could potentially run commands with the SYSTEM
privilege level. This issue is not remotely exploitable.
