CVE-2020-15381Network attack vector

JMX credential disclosure via cleartext transmission

Published Jun 9, 2021 · Updated Aug 4, 2024

Improper authentication in Broadcom Brocade SANnav before 2.1.1 exposes JMX server credentials to remote attackers in cleartext. The JMX component transmits authentication credentials without transport protection; Broadcom has not disclosed the responsible endpoint or code path. Access to the JMX network traffic is required, and the disclosed consequence is credential exposure rather than modification or service interruption.
