CVE-2023-22048: Vulnerability in the MySQL Server product of Oracle MySQL (component: Server: Pluggable Auth).

Vulnerability in the MySQL Server product of Oracle MySQL (component: Server: Pluggable Auth). Supported versions that are affected are 8.0.33 and prior. Difficult to exploit vulnerability allows low privileged attacker with network access via multiple protocols to compromise MySQL Server. Successful attacks of this vulnerability can result in unauthorized read access to a subset of MySQL Server accessible data. CVSS 3.1 Base Score 3.1 (Confidentiality impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:L/I:N/A:N).

Security readout for executives and security teams

Plain-English summary

CVE-2023-22048 is a low-severity Oracle MySQL Server issue in the Pluggable Auth component. A low-privileged attacker with network access could, under difficult conditions, read some MySQL Server data they should not access. The provided sources do not support active exploitation.

Executive priority

Schedule remediation in the normal vulnerability cycle, with faster handling for externally reachable or multi-tenant MySQL systems. Business urgency is limited by low CVSS score, high attack complexity, and lack of confirmed exploitation in the provided sources.

Technical view

Oracle describes affected supported MySQL Server versions as 8.0.33 and prior. The CVSS 3.1 vector is AV:N/AC:H/PR:L/UI:N/S:U/C:L/I:N/A:N, indicating network reachability, high attack complexity, required low privileges, no user interaction, and limited confidentiality impact.

Likely exposure

Exposure is most likely where MySQL Server 8.0.33 or earlier is reachable over the network and low-privileged database accounts exist. Internet-facing databases, shared hosting, and environments with broad internal database access deserve earlier review.

Exploitation context

The source bundle marks KEV as false and provides no cited evidence of exploitation in the wild. Oracle rates exploitation as difficult. Treat this as a confidentiality risk requiring normal patch management, not an emergency exploitation response.

Researcher notes

The public bundle does not include CWE mapping, root cause detail, proof-of-concept information, or the exact unauthorized data subset. Analysis should stay bounded to Oracle’s Pluggable Auth component description and the listed CVSS characteristics.

Mitigation direction

  • Identify MySQL Server instances running version 8.0.33 or earlier.
  • Review Oracle July 2023 CPU guidance for the applicable fixed release.
  • Apply vendor-supported MySQL updates through normal change control.
  • Restrict network access to MySQL from trusted application hosts only.
  • Review low-privileged database accounts and remove unnecessary access.

Validation and detection

  • Inventory MySQL Server versions across production, staging, and managed images.
  • Confirm whether any instance is version 8.0.33 or earlier.
  • Check database network exposure from internal and external segments.
  • Verify package status for Fedora or vendor-distributed MySQL builds.
  • Document compensating controls if patching must be delayed.
