Deeper analysis
CVE-2022-0824 is an improper access control vulnerability, tracked under CWE-284 and CWE-863, that leads to remote code execution in the Webmin web-based system administration tool. It affects all versions of the webmin/webmin GitHub repository prior to 1.990 and carries a CVSS 3.1 base score of 8.8.
An attacker with low-privileged authenticated network access and no user interaction required can exploit the flaw to execute arbitrary code, resulting in complete compromise of confidentiality, integrity, and availability on the affected host. Public proof-of-concept exploits have been published that demonstrate the path from broken access controls in components such as the file manager to full post-authentication RCE.
The referenced GitHub commit and project release notes indicate that the issue is resolved by upgrading to Webmin 1.990 or later; administrators should apply the update promptly and review any custom access-control configurations. The vulnerability shows a high EPSS score with a recorded peak of 0.9725 and a current value of 0.9268, indicating sustained 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.
The access control policy and procedures directly mandate and enforce proper access control mechanisms across the organization.
Supervision and review of access control activities directly detects and remediates improper access configurations or usages.
Associating and retaining security attributes with data directly supports enforcement of access control decisions across storage, processing, and transmission.
Requiring prior authorization for each remote access type prevents improper access control over remote connections.
Requiring authorization of wireless access before allowing connections enforces proper access control for this access method.
Requiring authorization and configuration controls for mobile device connections directly enforces access control and prevents unauthorized devices from reaching organizational systems.
Defining account types, requiring approvals for creation, specifying authorizations, monitoring usage, and reviewing accounts directly prevents improper access control by ensuring only authorized accounts exist and are used.
Enforces rules governing access to the system and its data from external systems based on established trust relationships.
