CVE-2023-27318Network attack vector

LDR service crash via uncaught exception

Published Feb 5, 2024 · Updated Aug 2, 2024

Denial of service in NetApp StorageGRID 11.6.0 through 11.6.0.13 allows remote authenticated users to crash the LDR service. NetApp identifies an uncaught exception in the Local Distribution Router but has not disclosed the triggering input or code path. Network access with low privileges is required, and successful exploitation interrupts the LDR service without reported confidentiality or integrity impact.
