# Onapsis Security Advisory 2022-0005: Cross-Site Scripting (XSS)  
vulnerability in SAP Fiori launchpad  
  
  
## Impact on Business  
  
Impact depends on the victim's privileges. In most cases, a successful  
attack  
allows an attacker to hijack a session, or force the victim to perform  
undesired  
requests in the SAP System (CSRF) as well as redirected to arbitrary web  
site  
(Open Redirect).

## Affected Components Description  
  
SAP Fiori launchpad is the entry point to ABAP platform for SAP Fiori apps  
on  
mobile and desktop devices.  
  
  
## Vulnerability Details  
  
During the navigation in SAP Fiori Launchpad, it is possible to provide a  
custom  
theme name using the url parameter ```sap-theme```. This parameter has an  
option to provide the path to a .css file, which it is used directly in the  
page  
generation. This optional input is not sufficiently sanitized, allowing an  
attacker to  
control and craft any kind of html payload in the page requested.  
  
  
## Solution  
  
SAP has released SAP Note 3149805 which provide patched versions of the

security fixes and apply them to the affected components in order to  
reduce business risks.
