CVE-2017-3265 in MySQL Server
Summary
by MITRE
Vulnerability in the MySQL Server component of Oracle MySQL (subcomponent: Server: Packaging). Supported versions that are affected are 5.5.53 and earlier, 5.6.34 and earlier and 5.7.16 and earlier. Difficult to exploit vulnerability allows high privileged attacker with logon to the infrastructure where MySQL Server executes to compromise MySQL Server. Successful attacks require human interaction from a person other than the attacker. Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all MySQL Server accessible data and unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of MySQL Server. CVSS v3.0 Base Score 5.6 (Confidentiality and Availability impacts).

The vulnerability identified as CVE-2017-3265 resides within the MySQL Server component of Oracle MySQL, specifically within the Server: Packaging subcomponent. This weakness affects multiple version ranges including 5.5.53 and earlier, 5.6.34 and earlier, and 5.7.16 and earlier, representing a significant portion of the MySQL server ecosystem. The vulnerability classification as difficult to exploit indicates that while it requires specific conditions to be successfully leveraged, the potential impact when exploited can be severe. The attack vector requires an attacker to possess logon credentials to the infrastructure where MySQL Server is executing, establishing a privileged access requirement that limits the attack surface but does not eliminate the threat.
The technical flaw associated with CVE-2017-3265 stems from improper handling within the server packaging mechanisms that can be manipulated by an attacker with sufficient privileges. This vulnerability operates under the Common Weakness Enumeration (CWE) framework, specifically relating to improper handling of packaging components that can lead to unauthorized access and system compromise. The vulnerability's exploitation requires human interaction from individuals other than the attacker, suggesting that social engineering or insider threats may play a role in successful exploitation scenarios. This characteristic places the vulnerability in the context of supply chain attacks or insider threat scenarios where legitimate users might inadvertently facilitate malicious activities.
The operational impact of successful exploitation presents multiple serious consequences for affected systems. The vulnerability can enable unauthorized access to critical data stored within MySQL Server instances, potentially exposing sensitive information that could range from user credentials to business-critical data. Additionally, the attack can grant complete access to all data accessible through the MySQL Server, representing a catastrophic data breach scenario. The availability impact is equally concerning as successful exploitation can cause the MySQL Server to hang or experience frequently repeatable crashes, resulting in complete denial of service conditions that can disrupt business operations and data accessibility. The CVSS v3.0 base score of 5.6 indicates a medium severity vulnerability, though the combination of confidentiality and availability impacts suggests that organizations should treat this vulnerability with significant concern.
Organizations should implement multiple layers of mitigation strategies to address this vulnerability effectively. The primary recommendation involves applying the relevant security patches provided by Oracle to upgrade to unaffected versions of MySQL Server. System administrators should also implement strict access controls and privilege management to limit logon credentials to only those individuals who require administrative access. Network segmentation and monitoring solutions should be deployed to detect unusual activities that might indicate exploitation attempts. The vulnerability's requirement for human interaction suggests that security awareness training for personnel could significantly reduce the risk of successful exploitation. Additionally, implementing database activity monitoring and anomaly detection systems can help identify potential exploitation attempts before they result in data compromise or service disruption. Organizations should also consider implementing the principle of least privilege and regularly review access permissions to ensure that only authorized individuals maintain the necessary privileges to access MySQL Server infrastructure.
