Information disclosure is when an application fails to properly protect sensitive and confidential information from
parties that are not supposed to have access to the subject matter in normal circumstances.
Carefully review every information disclosure vulnerablity in regards to disclosure obligations post-GDPR for ‘Personal data’ under the Data Protection Act 2018.
Risk specificationUnder certain conditions SAP Data Hub allows an attacker to access information which would otherwise be restricted.
The policies "sap.dh.developer" and "sap.dh.metdata" should only be assigned in development systems. For productive usage, it is not recommended to assign these policies to users. Instead, connection access should be whitelisted by 1. creation of a policy that provides access to a particular connection and 2. assigning that policy to users who are allowed to access it.
