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 specification
An unauthenticated attacker could read sensitive data from the SAP NetWeaver AS Java Heap dump application if a heap dump analysis has been performed on it.Solution
This note diables the Heap Dump application so that it is no longer accessible. Alternativly, the consulting team has proposed the following: "As soon as you do not need Heap Dump data anymore, you can and should delete the Heap Dump files. You find these files with extension .dmp or .hprof usually in folder /usr/sap/<SID>/<InstID>/j2ee/cluster/server<N>/ where N is the server node number.". The suggestion may be considered, as a workaround or compensating mitigation. We recommend installing/applying the correction wherever possible and as soon as possible. Base your decision on whether or not to apply the patch on your companies and systems risk perspective and consider the provided CVSS 5.3 score.
