webMethods Security Advisory
Glue console directory traversal vulnerability
Affects: webMethods Glue 4.x, 5.x, 6.x
On April 11 2007, Patrick Webster reported a vulnerability in Glue
on this list.
The vulnerability allows a user to remotely read any file on the
server where the Glue server is running. The full text of Patrick's
advisory is at http://www.aushack.com/advisories/200704-webmethods.txt.
If an unauthorized attacker can connect to the vulnerable product,
they can read any file on the target system by submitting a URL
such as http://glueconsole:8080/console?resource=c:\boot.ini
or http://glueconsole:8080/console?resource=/etc/passwd. No
authentication is required.
There are several optional workarounds:
(1) Disable the Glue console by editing the configuration files as
follows. This will prevent the attack, but limit the usability
of the system.
CAUTION: Changing these configuration files may render your system
unreliable. Back up all configuration files before making any changes.
Make the following changes to the web.xml file found in glue/WEB-INF:
* Remove the glue-console servlet definition
* Remove the glue-console servlet mapping
Make the following changes to the glue-config.xml file found in
* Change glue console enablement from "yes" to "no"
<!--enable the console by default?-->
(2) Block access to the /console URL by unauthorized users. This blocking
must be implemented using a third party product such as a firewall, and
does not exist in webMethods products. This workaround does not prevent
authorized users from reading any file on the system.
(3) If the Glue server is running on a UNIX system, run it within a
"chroot" environment to limit those files which can be read.
A fix is not currently available.
V. Versions Affected
