Operationally, exploitation aligns with the MITRE ATT&CK technique Path Interception (T1034); ranked in the top 3% of CVEs by exploit likelihood; CISA has added it to the Known Exploited Vulnerabilities catalog.
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-2022-22047 is an elevation-of-privilege vulnerability in the Windows Client Server Run-time Subsystem (CSRSS) that carries a CVSS 3.1 score of 7.8. The flaw is classified under CWE-426 and affects the CSRSS component responsible for managing Windows console sessions and related runtime services. It was publicly disclosed on 12 July 2022.
A local attacker who already possesses a low-privileged user account on an affected Windows system can exploit the weakness without user interaction. Successful exploitation grants the attacker full control over confidentiality, integrity, and availability on the host, effectively allowing transition from a standard user to SYSTEM-level privileges.
Microsoft’s security update guide provides patches that address the issue, and the vulnerability appears in CISA’s catalog of known exploited vulnerabilities, confirming that remediation should be prioritized through the supplied updates.
EPSS scores have remained low, with a recorded peak of 0.0150 and a current value of 0.0120, indicating limited observed exploitation interest after disclosure.

Mitigating Controls
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.
Preventing execution of unauthorized code directly blocks the malicious binaries that an untrusted search path would load.
Secure development practices include avoiding or sanitizing externally influenced search paths in application code.
Hardened configuration baselines can enforce safe search paths and restrict environment variables that enable the weakness.

Security testing can discover search-path issues but does not itself prevent them in production code.
Restricting software installation reduces the chance that untrusted binaries or libraries are placed in search paths.
Secure architecture principles include hard-coded or validated search paths and avoiding reliance on untrusted directories.
Secure coding standards require absolute paths or integrity-checked search paths, directly mitigating CWE-426.
Change-management processes can enforce review of path-handling changes, indirectly lowering risk.
