    CVE-2020-26829

    Published: 9 Dec 2020Last Modified: 10 Mar 2026

    Summary:

    Details: SAP NetWeaver AS JAVA (P2P Cluster Communication), versions - 7.11, 7.20, 7.30, 7.31, 7.40, 7.50, allows arbitrary connections from processes because of missing authentication check, that are outside the cluster and even outside the network segment dedicated for the internal cluster communication. As result, an unauthenticated attacker can invoke certain functions that would otherwise be restricted to system administrators only, including access to system administration functions or shutting down the system completely.
