Open Redirect in SAP HANA XSA UAA Server
Impact on Business
The open redirect vulnerability allows remote attackers to redirect users to arbitrary sites and conduct phishing attacks. The phishers may then steal victim’s credentials or other important data that can be used in other exploitation chains. This has limited impact on the confidentiality, integrity and availability of the system and its business applications.
Vulnerability Details
Due to improper input validation threat actors can craft a link that points to a legitimate domain, but when clicked by a victim, they will get redirected to an attacker-controlled site. The vulnerable endpoint is part of the User Account and Authentication service (UAA) for SAP HANA XS advanced model.
