Authenticated remote code execution
Published Jun 14, 2023 · Updated Feb 28, 2025
Deserialization of untrusted data in Microsoft Exchange Server allows remote authenticated users to execute code over an adjacent network. Microsoft identifies CWE-502 but does not disclose the affected component, deserialization entry point, or unsafe object-processing operation. Exploitation requires low-privileged authentication and adjacent-network reachability, and successful exploitation runs attacker-controlled code on the server.

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.
- Affected versionversion=15.02.0 <15.02.1118.030
