Since the vulnerability stems from insecure default TLS configurations, administrators should verify and update the TLS settings on affected devices to disable obsolete protocols and enable secure versions.
Description
Broadcom LSI Storage Authority (LSA) RAID Controller web interface uses an insecure default TLS configuration that supports obsolete and vulnerable TLS protocols. This constitutes the use of a broken or risky cryptographic algorithm, which can weaken the security of communications with the device.
