Advisory

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 3298961 was released on 11.04.2023 and deals with "[CVE-2023-28765] Information Disclosure vulnerability in SAP BusinessObjects Business Intelligence Platform (Promotion Management )" within BI/BO platform. We advice you to follow the instructions, to resolve information disclosure with a hot news potential for exploitation in component BI-BIP-LCM.

According to SAP Security Advisory team a workaround exists. 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.

Risk specification

SAP BusinessObjects Business Intelligence Platform (Promotion Management) allows an attacker with basic privileges to get access to the lcmbiar file and further decrypt the file. After this attacker can gain access to BI user’s passwords and depending on the privileges of the BI user, the attacker can perform operations that can completely compromise the application.

Solution

The application now properly secures access to the lcmbiar file. Alternativly, the consulting team has proposed the following: "As a workaround a Lifecycle Management Business Intelligence Archive with password can be used". 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 9.8 score.
