SAP Bex – Arbitrary Modification of Favorites Nodes Data
Impact on Business
An authenticated attacker with low privileges could modify or access data belonging to other users within the SAP Business Explorer (BEx) environment. This could lead to unauthorized data manipulation or access to sensitive workbooks, potentially compromising the integrity and confidentiality of business reports and data.
