Security Advisory 05 – 009 – Execute Of Arbitrary Reports

Vulnerable System:

Webseries Payment Application

Vulnerability discovery and development:

Portcullis Security Testing Services

Affected Systems:

Bottomline Webseries Payment Application


Portcullis consultants have discovered that by manipulating the values of certain Variables used during report selection it was possible to cause the application to download and execute arbitrary reports from any machine on the network capable of supporting Windows shares.

In normal usage the Webseries application references report templates located on the web server itself:



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.



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).


Exploit code not required.
