CVE-2023-36458Public exploitNetwork attack vector

Authenticated shell command execution via container identifier

Published Jul 5, 2023 · Updated Oct 18, 2024

Command injection in the container terminal of FIT2CLOUD 1Panel before 1.3.6 allows remote authenticated users to execute shell commands. The ContainerWsSsh handler in backend/app/api/v1/terminal.go accepts a crafted containerid value whose shell operators are processed as commands. Access to an authenticated panel session and the container terminal is required, and successful exploitation executes commands on the Linux server.
