Advisory

On 08.09.2020 a security relevant correction has been released by SAP SE. The manufacturer resolves an issue within SAP Adaptive Server Enterprise (ASE) .

SAP Note 2953203 addresses "[CVE-2020-6317] Information Disclosure in SAP Adaptive Server Enterprise" to prevent information disclosure with a low risk for exploitation.

A workaround does exist, according to SAP Security Advisory team. It is advisable to implement the correction as part of maintenance, the team suggests.

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

In certain situations, SAP Adaptive Server Enterprise allows a user with regular user credentials and local access to an ASE Cockpit installation to view unauthorized information that appears in the installation log. The log exists in the format of a file on the file system of the host.

Solution

In the patched version of SAP ASE Installer, the encrypted information is removed from the installation log file. Circumstances exist that prevent the timely installation of a patch provided by the manufacturer. In such cases, you may consider applying the suggested workaround as a temporary or compensating mitigation: "In case you are using the affected versions then remove the installation log file from your setup.".

The advisory is valid for

SYBASE_ASE_SERVER 15.7 ⁷
SYBASE_ASE_SERVER 16.0 ¹³
