Summary

CVE-2024-20430 is a high-severity Uncontrolled Search Path Element (CWE-427) vulnerability in Cisco Meraki Systems Manager. Its CVSS base score is 7.3 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Path Interception (T1034); ranked at the 10th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to CM-6 (Configuration Settings) and AC-3 (Access Enforcement) — see the control section below for these in your framework.

Vulnerability Data

A vulnerability in Cisco Meraki Systems Manager (SM) Agent for Windows could allow an authenticated, local attacker to execute arbitrary code with elevated privileges.  This vulnerability is due to incorrect handling of directory search paths at runtime. A low-privileged attacker…

could exploit this vulnerability by placing both malicious configuration files and malicious DLL files on an affected system, which would read and execute the files when Cisco Meraki SM launches on startup. A successful exploit could allow the attacker to execute arbitrary code on the affected system with SYSTEM privileges.

Mitigating Controls (NIST 800-53 r5) AI

Establishes restrictive configuration settings that can define and lock down approved search paths.

Enforces approved authorizations so that only intended actors can place or modify elements in the search path.

Limits privileges so unintended actors cannot write to or control directories in the product's search path.

Restricts logical and physical access to change system configuration, including search-path settings and directories.

finds

Security testing can detect uncontrolled search-path issues but does not prevent them by itself.

mitigates

Restricting software installation reduces the chance that an attacker-controlled path element is introduced into the search path.

mitigates

Secure system architecture and engineering principles require explicit control over search paths and resource locations.

prevents

Secure coding practices directly address the use of fixed or controlled search paths that can be influenced by unintended actors.

prevents

Configuration management can enforce approved search-path settings but does not inherently prevent the weakness.
