CVE-2023-22057: Vulnerability in the MySQL Server product of Oracle MySQL (component: Server: Replication).

Vulnerability in the MySQL Server product of Oracle MySQL (component: Server: Replication). Supported versions that are affected are 8.0.33 and prior. Easily exploitable vulnerability allows high privileged attacker with network access via multiple protocols to compromise MySQL Server. Successful attacks of this vulnerability can result in unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of MySQL Server. 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).

Security readout for executives and security teams

Plain-English summary

CVE-2023-22057 is a MySQL Server flaw that can let a highly privileged network attacker crash or hang the database. It does not indicate data theft or tampering, but a successful attack can cause a complete denial of service for affected MySQL Server versions 8.0.33 and earlier.

Executive priority

Treat this as a moderate availability risk. Prioritize internet-adjacent or business-critical MySQL systems, especially where privileged access is broadly distributed or third-party platforms bundle MySQL.

Technical view

Oracle identifies this as a MySQL Server Replication component vulnerability affecting supported versions 8.0.33 and prior. The CVSS vector is network-accessible, low complexity, high privileges required, no user interaction, unchanged scope, and high availability impact only.

Likely exposure

Exposure is most relevant where MySQL Server 8.0.33 or earlier is reachable over network protocols by administrators, replication operators, service accounts, or other high-privileged users.

Exploitation context

The source bundle does not show CISA KEV listing or cited evidence of active exploitation. Exploitation requires high privileges, limiting broad opportunistic risk, but database outages can be operationally serious.

Researcher notes

Public details in the bundle are limited to product, component, affected version range, CVSS, and denial-of-service impact. No CWE, root cause, proof-of-concept status, or detailed exploit mechanics are provided.

Mitigation direction

  • Apply Oracle July 2023 CPU guidance or vendor-provided patched MySQL packages.
  • Check NetApp, Fedora, or platform vendor advisories if MySQL is bundled.
  • Restrict MySQL network access to trusted administrative and application paths.
  • Review and reduce high-privileged MySQL accounts where feasible.
  • Monitor MySQL crash, restart, and hang indicators until patched.

Validation and detection

  • Inventory MySQL Server instances and record exact versions.
  • Flag Oracle MySQL Server 8.0.33 and earlier for remediation review.
  • Confirm patched package or vendor advisory status after updates.
  • Review network paths that allow privileged access to MySQL.
  • Check operational logs for unexplained MySQL hangs or repeated crashes.
