AI Analysis

Impact

A flaw in the Clone Plugin of Oracle MySQL Server and Cluster allows an attacker with high privileges and network access to deliberately cause the database service to hang or crash, resulting in a denial of service. The vulnerability is rated with a CVSS 3.1 base score of 4.9 and affects only availability, while confidentiality and integrity remain unchanged.

Affected Systems

Oracle MySQL Server version 8.4.0‑8.4.12, 9.7.0‑9.7.3, 26.7.0‑26.7.1 and Oracle MySQL Cluster version 8.0.0‑8.0.49, 8.4.0‑8.4.12, 9.7.0‑9.7.3, 26.7.0‑26.7.1 are impacted.

Risk and Exploitability

The CVSS score indicates a moderate severity focused on availability. The EPSS score is < 1%, suggesting a low likelihood of exploitation, and the vulnerability is not listed in the CISA KEV catalog. An attacker would require network connectivity to the MySQL instance and elevated privileges, likely an account with administrative rights; the attack can be performed through multiple protocols and would immediately lead to a service hang or crash, causing disruption to dependent applications.

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Apply the latest Oracle patch for MySQL Server or MySQL Cluster as soon as it is released
  • Restrict inbound traffic to MySQL ports to a limited set of trusted hosts or enforce firewall rules
  • If the Clone Plugin is not essential for your deployment, disable or uninstall it to eliminate the attack surface
  • Consider implementing a high‑availability or load‑balancing configuration that can automatically restart the service or shift traffic when a crash occurs
