CVE-2023-4339
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 to exposure of private keys used for CIM stored with insecure file permissions
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 stores CIM private keys with overly permissive file permissions, allowing unprivileged users to read sensitive cryptographic keys. This information disclosure could enable attackers to obtain the keys and authenticate to CIM services or perform man-in-the-middle attacks.

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 installationCheck if the Broadcom RAID Controller Web Interface is installed or running in your environment. This is typically accessed via a web browser to the controller's management IP.Affected if The web interface is present and accessible.
-
Check installed version numberAccess the web interface administrative console and locate the version information, typically found in About or System Information sections. The affected version is 51.12.0-2779.Affected if The installed version matches exactly 51.12.0-2779.
-
Locate CIM private key filesOn the controller management system, search for CIM-related private key files. These are typically stored in configuration or security directories related to the web interface.Affected if CIM private key files exist on the system.
-
Examine file permissions on CIM keysUse file system commands (such as ls -la or icacls) to inspect the permissions on identified CIM private key files. Check if they are readable by non-privileged or unauthorized users.Affected if File permissions allow read access to unprivileged users (e.g., world-readable, overly permissive ACLs).
You are affected if Broadcom RAID Controller Web Interface version 51.12.0-2779 is running AND CIM private key files have overly permissive file permissions allowing unprivileged access.

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 dataRestrict file permissions on CIM private key files to authorized administrators only, and regenerate any keys that may have been exposed.
