Published: 18 April 2023
Summary
CVE-2023-29411 is a critical-severity Missing Authentication for Critical Function (CWE-306) vulnerability in Microsoft Windows 10. Its CVSS base score is 9.8 (Critical).
Operationally, ranked in the top 7.9% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
Deeper analysis
A CWE-306 Missing Authentication for Critical Function vulnerability affects the Java RMI interface of the impacted product. The flaw permits unauthenticated modification of administrative credentials, which can be leveraged for remote code execution. It carries a CVSS 3.1 score of 9.8 reflecting network-accessible attack complexity with no required privileges or user interaction.
An unauthenticated remote attacker can directly target the exposed RMI interface to alter administrative credentials and subsequently execute arbitrary code on the affected system. No prior authentication or user interaction is needed, enabling straightforward exploitation over the network.
Vendor advisory SEVD-2023-101-04 from Schneider Electric addresses the issue and is available at the referenced URLs. The EPSS score remains low, with a current value of 0.0771 and a peak of 0.0826, indicating limited observed exploitation interest after disclosure.

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.
Requires established identification and authentication to unlock, mitigating missing authentication for continued system access.
Requiring identification and rationale for actions allowed without authentication ensures critical functions are not left unprotected by forcing review of authentication requirements.
Authorizing mobile device connections to organizational systems ensures authentication is performed for this critical access function.
Guarantees critical functions are protected by mandatory invocation of the access control mechanism.
Auditing sessions makes it possible to detect access to critical functions without required authentication.
The assessment process confirms authentication is present and effective for critical functions, preventing exploitation from missing authentication.
Certification assesses that critical functions have required authentication controls in place.
Disabling non-essential functions and services eliminates the need to secure them, reducing exposure from missing authentication on unnecessary components.
