Deeper analysis
MeterSphere version 1.20.20-lts-79d354a6 contains a remote command execution vulnerability in its workbench custom code snippet function. The flaw stems from improper handling of user-supplied input that is passed to system commands, corresponding to CWE-78 OS command injection, and carries a CVSS 3.1 score of 9.8 reflecting network-accessible, unauthenticated exploitation with full confidentiality, integrity, and availability impact.
An attacker with no credentials can send a crafted request to the affected endpoint and execute arbitrary operating-system commands, including the establishment of reverse shells. This grants complete control over the underlying host without requiring user interaction or elevated privileges.
