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-2022-34715 is a remote code execution vulnerability affecting the Windows Network File System component. It carries a CVSS 3.1 base score of 9.8 and is associated with CWE-94 code injection weaknesses, allowing an attacker to execute arbitrary code without any user interaction or authentication.

An unauthenticated attacker can exploit the flaw over the network by sending specially crafted NFS traffic to a vulnerable Windows system, resulting in full compromise of confidentiality, integrity, and availability on the target.

Microsoft Security Response Center advisories linked to the CVE provide official patch guidance and remediation details for affected Windows releases. The associated EPSS score has remained steady at 0.3892 with no material post-disclosure increase observed.

Mitigating Controls (NIST 800-53 r5) AI

prevent

Directly requires applying the vendor patch that eliminates the NFS RCE flaw before exploitation can occur.

prevent

Blocks unauthenticated NFS traffic from untrusted networks, preventing the crafted-packet attack path described in the CVE.

prevent

Disables or restricts the NFS service when not required, eliminating the attack surface for this unauthenticated RCE.

Mitigating Controls (NIST CSF 2.0) AI

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.

PR.PS-06 mostly match
prevents

PR.PS-06's SDLC practices directly target injection flaws via secure coding and testing (mostly), yet as a single broad outcome it leaves many code-generation specifics unaddressed (partial).

PR.DS-10 none match
prevents

PR.DS-10 protects runtime data confidentiality/integrity but has no bearing on neutralizing externally influenced input during code generation, so neither direction shows any preventive effect.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.

prevents

Banning unapproved code samples and unauthenticated web services, combined with secure-coding standards and SAST, prevents the dynamic generation or inclusion of attacker-supplied code.

none

Controls that restrict unauthorized or malicious code from being introduced via external networks or removable media limit opportunities for an attacker to inject and execute arbitrary code.
