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 · unedited
Broadcom RAID Controller web interface is vulnerable to insufficient randomness due to improper use of ssl.rnd to setup CIM connection

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 confidence

The Broadcom RAID Controller web interface uses ssl.rnd improperly for randomness when establishing CIM (Common Information Model) connections. This insufficient randomness in cryptographic operations could allow attackers to predict or brute-force session tokens or credentials, potentially gaining unauthorized administrative access to the RAID controller.

MitigationApply vendor-supplied firmware updates for affected Broadcom RAID controllers. If unavailable, restrict network access to the management interface and consider disabling CIM/remote management features until patching is possible.

Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify the RAID controller model
    Access the RAID controller BIOS, boot-time interface, or management CLI (e.g., storcli, perccli) to confirm the hardware is a Broadcom RAID controller. Note the model number.
    Affected if The system does not use a Broadcom RAID controller, then this CVE does not apply.
  2. Check the web interface version
    Log into the Broadcom RAID Controller web interface. Navigate to the About, Support, or System Information page. Locate the firmware/web interface version number.
    Affected if The installed version is exactly 51.12.0-2779, then this specific version is affected by the CVE.
  3. Verify CIM/remote management is enabled
    In the web interface, locate the CIM (Common Information Model), Remote Management, or iDRAC/Remote Access settings. Check if CIM/WBEM services are enabled or configured.
    Affected if CIM or remote management features are disabled, the attack surface is significantly reduced though the vulnerable code may still be present in the firmware.
  4. Assess network accessibility of management interface
    Determine if the RAID controller web interface is accessible over the network. Check the management IP address configuration, firewall rules, and whether remote access is permitted versus local-only access.
    Affected if The management interface is exposed to untrusted networks, an attacker could potentially exploit the weak randomness to intercept or brute-force session credentials.

You are affected if you have a Broadcom RAID Controller with web interface version 51.12.0-2779 and CIM/remote management is enabled and network-accessible.
