Who should care

System administrators and security teams responsible for MySQL Connectors, particularly those using versions 9.7.0-9.7.1, should be aware of this vulnerability and take necessary actions to mitigate the risk.

Technical summary

The vulnerability in MySQL Connectors (component: Connector/J) affects versions 9.7.0-9.7.1. It is difficult to exploit and requires a low-privileged attacker with network access via multiple protocols. Successful attacks can result in unauthorized creation, deletion, or modification access to critical data or all MySQL Connectors accessible data, as well as unauthorized access to critical data or complete access to all MySQL Connectors accessible data and unauthorized ability to cause a partial denial of service (partial DOS) of MySQL Connectors. The CVSS 3.1 Base Score is 7.1 (Confidentiality, Integrity, and Availability impacts). The CVSS Vector is (CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:L).

Defensive priority

High priority should be given to patching or mitigating this vulnerability, especially in environments where MySQL Connectors are exposed to the network.

Recommended defensive actions

  • Apply the latest patches or updates for MySQL Connectors to version 9.7.2 or later.
  • Restrict network access to MySQL Connectors to only necessary personnel and services.
  • Monitor MySQL Connectors logs for suspicious activity.
  • Consider implementing additional security measures such as encryption and access controls.
  • Review compensating controls for exposed systems while remediation is scheduled and verified.
  • Check relevant monitoring, detection, and logs for exposed assets that need extra review.
  • Track exceptions, retest remediated assets, and close the item only after evidence is documented.
