CVE-2017-3307 in MySQL Enterprise Monitor
Summary
by MITRE
Vulnerability in the MySQL Enterprise Monitor component of Oracle MySQL (subcomponent: Monitoring: Server). Supported versions that are affected are 3.1.6.8003 and earlier, 3.2.1182 and earlier and 3.3.2.1162 and earlier. Difficult to exploit vulnerability allows high privileged attacker with network access via multiple protocols to compromise MySQL Enterprise Monitor. Successful attacks require human interaction from a person other than the attacker. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of MySQL Enterprise Monitor accessible data and unauthorized ability to cause a partial denial of service (partial DOS) of MySQL Enterprise Monitor. CVSS 3.0 Base Score 3.1 (Integrity and Availability impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:H/UI:R/S:U/C:N/I:L/A:L).

The vulnerability identified as CVE-2017-3307 resides within the MySQL Enterprise Monitor component of Oracle MySQL, specifically within the Monitoring: Server subcomponent. This issue affects multiple version ranges including 3.1.6.8003 and earlier, 3.2.1182 and earlier, and 3.3.2.1162 and earlier, representing a significant attack surface for organizations utilizing enterprise monitoring solutions. The vulnerability classification as difficult to exploit indicates that while the attack vector exists, it requires specific conditions and circumstances to be successfully leveraged by threat actors. The CVSS 3.0 base score of 3.1 reflects the relatively moderate severity, though the combination of integrity and availability impacts creates a concerning threat profile for enterprise environments.
The technical flaw manifests as a privilege escalation vulnerability that requires high privileged attackers to gain network access through multiple protocols to compromise the MySQL Enterprise Monitor component. This architectural weakness allows attackers to potentially gain unauthorized update, insert, or delete access to sensitive data within the monitoring system, while simultaneously creating opportunities for partial denial of service conditions. The requirement for human interaction beyond the initial attack vector suggests that the vulnerability may involve social engineering elements or require specific user actions to complete the exploitation process, making it somewhat more challenging to deploy at scale. The CVSS vector analysis reveals that network-based attacks are possible with high complexity requirements, high privilege needs, and user interaction requirements, indicating a sophisticated attack scenario.
The operational impact of this vulnerability extends beyond simple data integrity concerns to encompass availability risks that can significantly affect enterprise monitoring capabilities. Organizations relying on MySQL Enterprise Monitor for database performance tracking and management may experience partial service disruption, potentially leading to monitoring gaps during critical system events. The unauthorized update, insert, or delete access to monitored data creates opportunities for data corruption or manipulation that could compromise the integrity of operational metrics and performance indicators. This vulnerability directly impacts the security posture of enterprise database environments, as compromised monitoring systems can mask actual security incidents or provide attackers with valuable information about system behavior and performance characteristics.
Mitigation strategies for CVE-2017-3307 should prioritize immediate patch management and version updates to ensure affected systems operate on supported releases. Organizations must implement network segmentation controls to limit access to monitoring components and establish strict access controls for privileged accounts. The requirement for human interaction suggests that user awareness training and security awareness programs should be enhanced to prevent social engineering attacks that might exploit this vulnerability. Network monitoring and intrusion detection systems should be configured to detect unusual access patterns to monitoring components, while regular security assessments should verify that monitoring systems maintain their integrity and availability. This vulnerability aligns with CWE-284 (Improper Access Control) and represents a typical example of how monitoring systems can become attack vectors when not properly secured, potentially mapping to ATT&CK techniques involving privilege escalation and credential access through network-based attacks.
