01

What, why and how

External control of file name or path in Windows Core Shell allows an unauthorized attacker to perform spoofing over a network.

What

External control of file name or path in Windows Core Shell allows an unauthorized attacker to perform spoofing over a network.

Why

The product allows user input to control or influence paths or file names that are used in filesystem operations.

How

An attacker operating through a network path may attempt exploitation without authentication after a user interaction. If successful, the issue may cause the confidentiality, integrity or availability impact described by the vendor.

02

Exploit reality and attack path

CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.

Observed exploitation
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
No confirmed evidence

No CISA KEV match was present at the last successful refresh. This means no confirmation from that source, not proof of no exploitation.

Public PoC / exploit material
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
None recorded

No exploit-tagged reference or CISA SSVC proof-of-concept state is currently recorded. Research may still exist outside the structured feeds.

Likely attack path
a network path → External Control of File Name or Path → cause the confidentiality, integrity or availability impact described by the vendor

Weakness

CWE-73 ↗

CWE-73: External Control of File Name or Path. The product allows user input to control or influence paths or file names that are used in filesystem operations.
