CVE-2020-10879Public exploitNetwork attack vector

Authenticated command execution via unescaped nodeId

Published Mar 23, 2020 · Updated Aug 4, 2024

Command injection in rConfig before 3.9.5 allows remote authenticated users to execute arbitrary OS commands through a crafted GET request. The lib/crud/search.crud.php endpoint passes the nodeId parameter directly to PHP exec without escaping shell metacharacters. The published exploit logs in with a valid rConfig account and places shell operators in nodeId to start a reverse shell under the web application process.
