Deeper analysis
Microsoft PostScript and PCL6 Class Printer Driver contains an information disclosure vulnerability tracked as CVE-2023-24906. The flaw affects the printer driver component in supported Microsoft Windows versions and is rated 6.5 under CVSS 3.1, reflecting network attack vector, low attack complexity, and low-privileged access requirements that result in high confidentiality impact without affecting integrity or availability. The associated CWEs indicate an integer overflow condition that leads to exposure of resources outside their intended scope.
An authenticated attacker with low privileges can send specially crafted print jobs or driver requests over the network to trigger the flaw and obtain sensitive information from the affected system. No user interaction is required, allowing the attacker to read data that would otherwise be inaccessible.
Microsoft’s security advisory recommends applying the updates released in the March 2023 Patch Tuesday cycle to remediate the issue. The EPSS score has remained flat at 0.1077 since disclosure, indicating no material increase in observed exploitation interest.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Controls whether organization resources are exposed to external system spheres by permitting or prohibiting their use.
The control ensures information is not released into a security sphere where the recipient lacks matching access authorizations.
The control ensures information resources are not exposed to the incorrect (public) sphere through review and authorization.
Protects against data mining that would expose resources to unauthorized spheres by enforcing detection and controls.
Restricts information flows to ensure resources are not exposed to incorrect or unauthorized spheres.
Controlling internal connections prevents exposure of resources to unintended internal spheres.
Knowing exact processing and storage locations helps avoid exposure of resources to incorrect spheres.
The control prevents exposure of the media resource to the wrong security sphere.
