SAP takes the security of its vast product portfolio very seriously and thus releases security fixes for
vulnerabilities reported by external researchers and their customers every second Tuesday of the month.
SAP Note 2842034
was released on
12.11.2019 and deals with
"[CVE-2019-0390] Information Disclosure in SAP Data Hub" within SAP Data Hub.
We advice you to follow the instructions, to resolve information disclosure with a
medium potential for exploitation
in component EIM-DH.
According to SAP Security Advisory team a workaround does not exist. It is advisable to implement the correction as part of maintenance.
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.
Under 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.
The advisory is valid for
- DH_FOUNDATION 2
ABEX takes the security of SAP products very seriously. We very much encourage the responsible disclosure of security vulnerabilities. If you have detected a vulnerability in one of the SAP software products – either in the latest or in a former product version follow the guidelines and processes in accordance with the SAP portal page “Report a Security Vulnerability to SAP”.
The advisories found within the ABEX security advisory are generated and continuously enriched by ABEX and affiliated security consultants, partners, customers of the SecurityBridge security suite, SAP support, and advisory groups.
There is no disclosure of zero-day vulnerabilities. In such case, the platform only provides details on which version or signature updates are available within the SecurityBridge platform in order to monitor or measure the vulnerability
In accordance with SAP guidelines, ABEX only discloses issues where the fixing security note has been released at least three months ago. The vulnerability platform makes no references to available exploits or Proof of Concepts (PoC). Advisories and vulnerabilities will always mention the fixing security note or hints to the corresponding SAP documentation.
