CVE-2024-20430 is a high-severity vulnerability rated 7.3/10 on the CVSS scale. 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. EPSS estimates a 0.20% chance of exploitation in the next 30 days.
