Horizon Alert
Summary of the vulnerability and why it matters
This advisory concerns a critical vulnerability found in the web interface of Broadcom RAID controllers. The flaw stems from how the system generates random numbers for security connections, potentially allowing unauthorized access and control over data storage. The main concern is confirming relevance and exposure within our environment.
- Weak randomness in RAID controller web interface.
- Affects data security and system integrity.
- Confirm relevance and exposure.
Attack Path
How an attacker could exploit the issue
An attacker could exploit this by targeting the web interface of a Broadcom RAID controller. This interface, if exposed to the network, could allow an unauthenticated attacker to leverage insufficient randomness in setting up a CIM connection. Successful exploitation could lead to a compromise of the controller's confidentiality, integrity, and availability.
- Network access required.
- Insecure connection setup triggers vulnerability.
- Compromise confidentiality, integrity, availability.
Live Threat
Current exploitation, exposure, and threat context
The Broadcom RAID Controller web interface's insufficient randomness could allow an attacker to compromise the confidentiality, integrity, and availability of the system. This is possible when the SSL random number generator is improperly used during the setup of a CIM connection, potentially leading to predictable cryptographic material.
- System data and integrity at risk.
- Predictable cryptographic material used.
- Potential for system compromise.
Operational Fix
Recommended remediation, mitigation, and detection steps
The Broadcom RAID Controller web interface vulnerability requires action from infrastructure and security teams responsible for managing storage and network-accessible hardware. The first practical step is to inventory all instances of the affected RAID controller web interface, determine their network reachability and criticality to business operations, identify the specific system owners, and then prioritize remediation based on exposure.
- Infrastructure and Security teams own this issue.
- Verify network reachability and system criticality.
- Plan vendor coordination for remediation.
