Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2023-36596 is a Remote Procedure Call Information Disclosure Vulnerability affecting Microsoft components responsible for handling RPC communications. It received a CVSS 3.1 score of 7.5 reflecting network-accessible exposure with no required authentication or user interaction that can result in high-impact confidentiality loss while leaving integrity and availability unaffected. The issue is also associated with CWE-822 and CWE-668.

An unauthenticated remote attacker can exploit the flaw to disclose sensitive information from the targeted system. No special privileges or user interaction are needed for successful exploitation.

Microsoft publishes mitigation details for this vulnerability in its Security Response Center update guide at the referenced URL. The EPSS probability rose from a low baseline after disclosure to a peak of 0.0532 on 2025-01-22 before receding to the current value of 0.0030, indicating a period of increased exploitation interest that later subsided.

Likely Mitigating Controls AI

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.

addresses: CWE-668

Controls whether organization resources are exposed to external system spheres by permitting or prohibiting their use.

addresses: CWE-668

The control ensures information is not released into a security sphere where the recipient lacks matching access authorizations.

addresses: CWE-668

The control ensures information resources are not exposed to the incorrect (public) sphere through review and authorization.

addresses: CWE-668

Protects against data mining that would expose resources to unauthorized spheres by enforcing detection and controls.

addresses: CWE-668

Restricts information flows to ensure resources are not exposed to incorrect or unauthorized spheres.

addresses: CWE-668

Controlling internal connections prevents exposure of resources to unintended internal spheres.

addresses: CWE-668

Knowing exact processing and storage locations helps avoid exposure of resources to incorrect spheres.

addresses: CWE-668

The control prevents exposure of the media resource to the wrong security sphere.

finds

Security testing can detect pointer-dereference flaws before release.

mitigates

Placing systems of differing trust levels into separate domains prevents resources from being placed in a sphere where they are reachable by unintended actors.

prevents

Secure development lifecycle includes pointer-safety practices that reduce untrusted pointer dereference risk.

prevents

Application security requirements can mandate validation of pointers obtained from untrusted sources.

prevents

Secure architecture principles discourage direct use of untrusted values as pointers.

prevents

Secure coding standards explicitly forbid dereferencing pointers derived from untrusted input.
