Description

The researcher was able to extract contents of files using the pdf-generator in "Yearly Financial Statements". This was done by adding an IFRAME-tag inside the companyname. Once rendered in Yearly Financial Statements, it included the file the IFRAME was pointing to. In this POC it was /etc/passwd.
