Unauthenticated user enumeration via password-reset parameter
Published Dec 5, 2022 · Updated Apr 23, 2025
User enumeration in MegaRAC SP-X allows remote attackers to identify valid accounts through unauthenticated password-reset requests. A manipulable password-reset parameter makes the API response distinguish whether a supplied username exists. No prior authentication is required; the result supplies account names for later brute-force or credential-stuffing attempts without changing device state.

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=0 <=SPx12-update-6.00
