An attacker can trigger a condition in which a process ceases to run. This condition can be intentionally provoked by the attacker to cause a denial of service.

Business risk

An attacker can use a Buffer overflow vulnerability to inject specially crafted code into a working memory which will be executed by a vulnerable application. Executed commands will run with the same privileges as the service that executed the command. It can lead to taking complete control of the application, denial of service, command execution, and other attacks. In case of command execution, the attacker can obtain critical technical and business-related information stored in a vulnerable SAP system or use it for privilege escalation. Speaking about denial of service, terminating a process of the vulnerable component is possible. For this time nobody can use this service, this fact negatively influences on business processes, system downtime and, as a result, business reputation.
