CVE-2024-34688Network attack vector

Service interruption via unrestricted repository service access

Published Jun 11, 2024 · Updated Aug 2, 2024

Uncontrolled resource consumption in SAP NetWeaver AS Java MMR_SERVER 7.5 allows remote attackers to interrupt application service. The Meta Model Repository services accept unauthenticated network requests without access restrictions, allowing callers to consume resources until the application stops serving legitimate users. Network access alone is sufficient, and the reported consequence is loss of availability without disclosure or modification of application data.
