SAP security note 2588567, "Cross-Site Scripting (XSS) vulnerability in SAP CRM WebClient UI", is a note. Below are the symptom and SAP recommended solution.
Description
Symptom
SAP CRM WebClient UI does not sufficiently encode user-controlled inputs, resulting in a Cross-Site Scripting (XSS) vulnerability.
Some well-known impacts of XSS vulnerability are:
- Non-permanently deface or modify displayed content from a website
- Steal authentication information of the user, such as data relating to their current session
- Impersonate the user and access all information with the same rights as the target user
- Unauthorized execution of commands
Solution
Input encoding and validation have been added. Please implement the solution below or install the equivalent Support Package.
Reason and prerequisites
CRM WebClient UI does not encode or validate untrusted input. The attacker needs to trick an already authenticated user to visit a prepared website to launch the attack.
