SAP security note 2541610, “Cross-Site Scripting (XSS) vulnerability in SAP CRM WebClient UI”. 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.
- 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. An attacker needs to trick an already authenticated user into visiting a prepared website to launch the attack.
CVSS
Score 6.1 Vector: CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N
