Description
Vulnerability in the MySQL Server, MySQL Cluster product of Oracle MySQL (component: InnoDB). Supported versions that are affected are MySQL Server: 9.7.0-9.7.1; MySQL Cluster: 9.7.0-9.7.1. Easily exploitable vulnerability allows high privileged attacker with network access via multiple protocols to compromise MySQL Server, MySQL Cluster. Successful attacks of this vulnerability can result in unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of MySQL Server, MySQL Cluster. CVSS 3.1 Base Score 4.9 (Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:H).

AI Analysis

Impact

The vulnerability resides in the InnoDB component of MySQL Server and MySQL Cluster. An attacker with high‑privilege access who can reach the database via standard protocols can trigger a crash or hang, resulting in a complete denial of service. The flaw is a classic denial‑of‑service weakness that disables service availability without compromising confidentiality or integrity.

Affected Systems

Affected products are Oracle MySQL Server and MySQL Cluster. Versions 9.7.0 through 9.7.1 are vulnerable; there is no explicit statement in the CVE that later versions are safe, so risk remains until updated.

Risk and Exploitability

The CVSS v3.1 base score of 4.9 reflects the availability impact and the need for high‑privilege access. The EPSS score is less than 1 %, indicating a low probability of exploitation; the vulnerability is not listed in CISA’s KEV catalog. The attack vector requires network access via MySQL’s native protocols and high‑privilege access, but does not provide persistence or data exfiltration.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Upgrade MySQL Server or MySQL Cluster to a version newer than 9.7.1.
  • Limit MySQL network exposure by restricting inbound connections to trusted hosts and applying firewall rules.
  • Implement monitoring of system metrics and log entries for sudden hangs or crashes, and alert on repeated failure patterns.
