We advice you to follow the instructions, to resolve code injection with a hot news potential for exploitation in component MFG-DM-EDGE.

According to SAP Security Advisory team a workaround exists. It is advisable to implement the correction as part of maintenance.

Risk specification

The component log4j allows an attacker to execute malicious code when he is in control of log messages or message parameters.

Solution

The applications dependencies were updated to a newer release that no longer contains these log4j vulnerabilities. Alternativly, the consulting team has proposed the following: "If possible, set the java parameter log4j2.formatMsgNoLookups=true". 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 10.0 score.
