Title: Metrica Service Assurance Multiple Cross Site Scripting
Vendor: IBM
***********************************************************************
Summary
Metrica Service Assurance Framework implements a distributed,
object-oriented, J2EE-based architecture. It work with a Web-based
user interfaces, from end-user report generation to detailed system
administration and configuration.
***********************************************************************
Vulnerability Detail
The web-based interface of Metrica Service Assurance is exposed to
multiple XSS attack. With an authenticated user it's possible to steal
other user's sessions due to a flaw in the input validation
mechanisms.
A persistant XSS permits the insertion of malicious code into the
web-based interface. Using the report generation function it is
possible to create a report with malicious code in the name.
That code is than rendered on the victim's browser when opening the
report history which can be found in the main panel of the
application.
The code also persists into the main panel and all the users are
exposed to the attack.
There are at least three vulnerable pages:
Non persistant:
* http://server/<document root>/ReportTree
* http://server/<document root>/Launch
Peristant:
* http://server/<document root>/ReportRequest
