CVE-2020-6183 Unprivileged Access to technical data using SAPOSCOL of SAP Host Agent, SAP security note 2836445

Description

The SAP Oscollector allows an unauthenticated attacker to query the background service that would otherwise be restricted to authorized users. The SAP Oscollector being an application that is usually only exposed internally, attacks are only possible from within this network. Once this vulnerability is exploited, the attacker can get statistics like CPU, RAM, directory size, and others. Attacker may be able to stop the collection process, thus affecting the availability of the service itself. If the attacker doesn’t have access to SAPOSCAL binary, they could just copy it to their home folder and perform the attack.
