CVE-2018-8016

31
FAUCET Score

CVE-2018-8016 is a critical vulnerability affecting Apache Cassandra versions 3.8 through 3.11.1, where the default configuration exposes an unauthenticated JMX/RMI interface on all network interfaces. This allows remote attackers to execute arbitrary Java code via an RMI request, stemming from a regression of a previous vulnerability. With a CVSS score of 9.8 (CRITICAL), this vulnerability has a network attack vector, low attack complexity, and high impact on confidentiality, integrity, and availability. While no active exploitation, Metasploit, Nuclei, or ExploitDB entries are reported, and community discussion is minimal, the high FAUCET Risk Score indicates its potential severity.
