Service interruption via improper null termination
Published Jul 11, 2023 · Updated Jan 1, 2025
Improper null termination in Windows Deployment Services on affected Windows Server builds allows remote authenticated users to interrupt service. Microsoft identifies the weakness class but has not disclosed the parsing locus, affected input, or exact failure path. Network access with low privileges is required, and successful exploitation affects availability only by interrupting WDS.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
