PasswordManager Pro 6.1 Script Injection Vulnerability|
scip AG Vulnerability ID 4063 (12/15/2009)

sensitive information such as passwords, documents and digital
identities of enterprises."

Stefan Friedli at scip AG (Switzerland) found an input validation error
within the current release, which enabled an attacker to perform various
The processing method for the search function fails to perform proper
input validation on the data that is being submitted via HTTP GET. The
parameter "searchtext" lacks validation and is therefore vulnerable to
script injection. While there is a basic input filterting method in
place, it fails to detect more advanced (e.g. encoded) payloads.
Other parts of the application might be affected too.
This vulnerability has been tested on version 6.1, other versions might
be affected as well.
Classic script injection techniques and unexpected input data within a
browser session can be used to exploit these vulnerabilities. The target
application does actually check for certain patterns and prevents an
attacker from using easy exploiting strings containing substrings like
be an imperfect mechanism that is unable to prevent an attack using a
more sophisticated payload. For a selection, you might want to check
RSnakes popular XSS Cheat Sheet, which contains several patterns not
being detected by the filter in place, allowing you execute any
arbitrary, externally hosted payload.
Exploitation can be performed using any medium, that is able to perform
a GET request. Under certain circumstances, it is even possible to
attack unauthenticated user, as the payload will be kept in the users
session until authentication data has been entered.
We exploited the vulnerability for a customer in order to proof the
possibility to capture usernames and passwords. One of the possibilities
mentioned above is, to embed a remote flash file and grant it the
permission to execute script code.
Impact of the vulnerability depends on the stored data. PMP is often
used for corporate password management and contains highly sensitive
information. Therefore, a high amount of damage might be caused by
successful exploitation and follow-up attacks.
Detection of web based attacks requires a specialized web proxy and/or
intrusion detection system. Patterns for such a detection are available
and easy to implement. Usually the mathematical or logical symbols for
less-than (<) and greater-than (>) are required to propose a HTML tag.
In some cases single (') or double quotes (") are required to inject the
code in a given HTML statement. Some implementation of security systems
are looking for well-known attack tags as like <script> and attack
attributes onMouseOver too. However, these are usually not capable of
identifying highly optimized payload.

VII. VENDOR RESPONSE
The issue is due to the filter applying case sensitive checks to the
attack strings and the situation of such a string with different cases
of characters was not handled. (09.12.2009; ManageEngine)
