CVE-2023-4345
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 · uneditedBroadcom RAID Controller web interface is vulnerable client-side control bypass leads to unauthorized data access for low privileged user
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 · moderate confidenceBroadcom RAID Controller web interface contains a client-side control bypass vulnerability that allows authenticated users with low privileges to access data beyond their authorized scope. This type of flaw typically involves tampering with client-side parameters, hidden fields, or session tokens to escalate privileges or access restricted resources.

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 Broadcom RAID Controller Web Interface presenceAccess the RAID controller management interface via its web URL (typically https://<controller-ip> or https://<server-ip>/raid) and verify the product is Broadcom RAID Controller Web Interface. Check the login page or about section for product identification.Affected if The product is not a Broadcom RAID Controller Web Interface, the user is not affected by this specific CVE.
-
Check installed web interface versionLocate the version information in the web interface (usually in Help > About, System Information, or the footer of the web pages). The exact version must be 51.12.0-2779 to be affected.Affected if The installed version is exactly 51.12.0-2779, this specific CVE applies. Versions other than 51.12.0-2779 are not affected by this exact vulnerability.
-
Verify web interface is accessible and enabledConfirm the RAID controller web management interface is reachable and functional. Attempt to access the login page or any authenticated section of the interface.Affected if The web interface is not enabled or not accessible, the client-side bypass cannot be exploited.
-
Confirm low-privilege user account existenceCheck if there are any user accounts with restricted or low-level privileges configured in the RAID controller user management section (typically under User Management, Access Control, or Security settings).Affected if No low-privilege users exist (only administrator accounts), the privilege escalation aspect of this vulnerability does not apply.
The environment is affected only if it uses Broadcom RAID Controller Web Interface version 51.12.0-2779 with the web interface enabled and configured with user accounts that have limited privileges.

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-provided patches or firmware updates for Broadcom RAID Controllers. If no patch is available, implement additional server-side authorization controls and restrict web interface access to trusted networks or users.
