Summary

The SAP NetWeaver ABAP Server and ABAP Platform is susceptible to an input validation vulnerability that allows unauthenticated attackers to send maliciously crafted packets over the network. This can lead to a system crash as the platform fails to properly validate the input in the ThSncIn() method. Consequently, the affected system becomes unavailable, although data cannot be viewed or modified due to the nature of the attack. Users of the affected versions should apply security patches to mitigate this risk.
