48
FAUCET Score

CVE-2016-4338 describes a shell command injection vulnerability in the Zabbix agent's userparameter_mysql.conf script, affecting versions before 2.0.18, 2.2.13, and 3.0.3, specifically when a non-bash shell is used. This flaw allows unauthenticated attackers to execute arbitrary code or SQL commands through the mysql.size parameter. With a CVSS score of 8.1 (High) and a FAUCET Risk Score of 98/100, this vulnerability presents a significant risk due to its network-based attack vector, high impact on confidentiality, integrity, and availability, and relatively low attack complexity.
