CVE-2021-40499Network attack vector

Unauthenticated code execution through client-side printing services

Published Oct 12, 2021 · Updated Aug 4, 2024

Code injection in SAP NetWeaver Application Server for ABAP print services before 7.70 allows remote attackers to execute code. SAP identifies SAPSprint and SAP Cloud Print Manager as the affected client-side services but has not disclosed the exact parsing locus or unsafe operation applied to print input. Network reachability is sufficient under NVD's assessment, and the affected lines are before 7.70, before 7.70 PI, and before 7.70 BYD.
