CVE-2023-37234Network attack vector

Unauthenticated JMX registry access

Published Sep 10, 2024 · Updated Sep 11, 2024

Improper access control in Loftware Spectrum 4.6 and earlier allows remote attackers to access its JMX registry without authentication. The Spectrum Application Server exposes the JMX registry without enforcing authentication before accepting remote connections. Network reachability to the registry is the only reported gate; public records establish information disclosure but do not identify exposed MBeans or data.
