Authenticated code execution via WebDAV buffer overflow
Published Aug 5, 2022 · Updated Jun 2, 2026
Stack-based buffer overflow in ASUSTOR Data Master WebDAV allows remote authenticated users to execute arbitrary code on NAS appliances. The WebDAV path fails to validate attacker-controlled data sizes before placing data in a stack buffer, allowing the buffer to be overrun. A valid ADM account and an enabled WebDAV service are required, and successful exploitation executes attacker-controlled code on the appliance.

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=3.5 <=3.5.9.RUE3
- Affected versionversion=4.0 <=4.0.5.RVI1
- Affected versionversion=4.1 <=4.1.0.RJD1
