Microsoft PostScript and PCL6 Class Printer Driver Information Disclosure Vulnerability

Security readout for executives and security teams

Plain-English summary

This is a Windows printer driver information disclosure issue. It is not rated as remote code execution, but Microsoft’s CVSS indicates a local, low-privileged user could expose highly sensitive information. Business urgency is moderate and should be handled through normal Windows patch governance.

Executive priority

Treat as a moderate-priority confidentiality issue. It does not indicate remote takeover, but affected Windows fleets should be patched because successful exploitation could disclose sensitive information to a local low-privileged user.

Technical view

CVE-2023-35306 affects Microsoft PostScript and PCL6 Class Printer Driver across listed Windows client and server versions. The CVSS vector is local, low complexity, low privileges required, no user interaction, confidentiality high, and no integrity or availability impact. CWE-20 is listed.

Likely exposure

Exposure is likely on affected Windows 10, Windows 11, Windows Server 2012/2016/2019/2022 systems before the applicable Microsoft remediation. The source bundle does not prove exposure beyond the listed products and versions.

Exploitation context

CISA KEV status is false in the bundle, and the CVSS exploit maturity is unproven. The sources do not show active exploitation, public exploit availability, or remote unauthenticated attack paths.

Researcher notes

The public bundle is sparse: it identifies the component, affected Windows versions, CWE-20, CVSS, and Microsoft advisory, but not root-cause details or exploit mechanics. Avoid assuming printer service configuration changes are sufficient without Microsoft guidance.

Mitigation direction

  • Use Microsoft’s advisory to identify applicable updates for each Windows version.
  • Install the relevant Microsoft security updates through normal patch management.
  • Prioritize systems allowing local interactive or shared-user access.
  • Review vendor guidance before applying compensating controls not named in sources.

Validation and detection

  • Inventory Windows versions against the affected product list.
  • Verify CVE-2023-35306 remediation status in patch management records.
  • Check whether affected server core installations are included in scope.
  • Confirm exceptions are documented with owner, reason, and remediation date.
