CVE-2020-2925: Vulnerability in the MySQL Server product of Oracle MySQL (component: Server: PS).

Vulnerability in the MySQL Server product of Oracle MySQL (component: Server: PS). Supported versions that are affected are 8.0.19 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 3.0 Base Score 4.9 (Availability impacts). CVSS Vector: (CVSS:3.0/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-2020-2925 is a MySQL Server availability flaw. An attacker who already has high privileges and network access can make affected MySQL Server versions hang or crash repeatedly. The business impact is service disruption, not data theft or data modification based on the supplied CVSS details.

Executive priority

Treat this as a moderate operational resilience issue. Prioritize production MySQL systems that support customer-facing or critical internal services, especially where many administrators or automation accounts have high privileges.

Technical view

Oracle lists the issue in MySQL Server component Server: PS, affecting supported versions 8.0.19 and prior. CVSS 3.0 is 4.9 with network attack vector, low complexity, high privileges required, no user interaction, unchanged scope, and high availability impact only.

Likely exposure

Exposure is most likely where MySQL Server 8.0.19 or earlier remains reachable over network-accessible database protocols by highly privileged accounts. Internet exposure is not required by the description, but broad internal reachability and shared administrative accounts increase operational risk.

Exploitation context

The supplied bundle does not show CISA KEV listing or active exploitation evidence. The vulnerability is described as easily exploitable once the attacker has high privileges and network access. No public exploit details are provided in the bundle.

Researcher notes

The source bundle provides affected version range, CVSS vector, and availability impact, but no CWE, root-cause detail, proof-of-concept status, or fixed version mapping. Validation should focus on version/package state, privilege boundaries, and network reachability rather than exploit reproduction.

Mitigation direction

  • Apply Oracle or operating-system vendor updates for MySQL Server from the cited advisories.
  • Check vendor guidance for the exact fixed package or MySQL release.
  • Restrict MySQL network access to trusted application hosts and administration networks.
  • Review and reduce high-privilege MySQL accounts where operationally possible.
  • Monitor MySQL availability, crashes, and unexpected restarts until patched.

Validation and detection

  • Inventory MySQL Server instances and identify versions 8.0.19 and earlier.
  • Compare installed packages against Oracle, Ubuntu, Fedora, Gentoo, or appliance vendor advisories.
  • Confirm high-privilege database accounts cannot connect from unnecessary network locations.
  • Review MySQL error logs and service history for repeated crashes or hangs.
  • Document compensating controls for any instance that cannot be updated promptly.
