Risk specification

This note has been re-released with updated ‘Symptom’ information. For the release SOLMANDIAG 720, we added SP011 and the Patch level 000004. - SAP Solution Manager User-Experience Monitoring does not perform any authentication for a service resulting in complete compromise of all SMDAgents connected to the Solution Manager. The risk rises since a public exploit exists!

Solution

SAP Solution Manager User-Experience Monitoring now properly checks the authentication. 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: "Manual activation of EemAdmin authentication as described in the note is a partial fix.
