SAP UI5 versions before 1.38.49, 1.52.49, 1.60.34, 1.71.31, 1.78.18, 1.84.5, 1.85.4, 1.86.1 allows an unauthenticated attacker to redirect users to a malicious site due to Reverse Tabnabbing vulnerabilities.
The SAP Gateway, versions 7.5, 7.51, 7.52 and 7.53, allows an attacker to inject content which is displayed in the form of an error message. An attacker could thus mislead a user to believe this information is from the legitimate service when it's not.
