CVE-2023-47577
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedAn issue discovered in Relyum RELY-PCIe 22.2.1 and RELY-REC 23.1.0 allows for unauthorized password changes due to no check for current password.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThe Relyum RELY-PCIe and RELY-REC devices fail to validate the current password when processing password change requests, allowing any authenticated or unauthenticated attacker to reset arbitrary user passwords without knowing the existing credentials. This is a critical authentication bypass that enables full account takeover.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify Relyum devices in your environmentInventory network devices or check device labels/models to locate RELY-PCIe or RELY-REC hardwareAffected if You have deployed Relyum RELY-PCIe or RELY-REC devices
-
Check RELY-PCIe firmware versionAccess the device management interface or use firmware version check command (e.g., 'show version' or via web UI)Affected if Firmware version equals 22.2.1 exactly
-
Check RELY-REC firmware versionAccess the device management interface or use firmware version check command (e.g., 'show version' or via web UI)Affected if Firmware version equals 23.1.0 exactly
-
Verify password change functionality exposureDetermine if the device web interface or API endpoint for password change is reachable from network segments accessible to usersAffected if Password change interface is exposed without additional access controls beyond authentication
You are affected if you have a Relyum RELY-PCIe device running firmware 22.2.1 or a RELY-REC device running firmware 23.1.0 with accessible password change functionality.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply vendor firmware patch when available; until then, restrict network access to management interfaces via firewall rules or VLAN segmentation, and monitor for unauthorized password change attempts in logs.
