Help Center/ Host Security Service/ Best Practices/ Suggestions on How to Fix Official Disclosed Vulnerabilities Provided by HSS/ SaltStack Remote Command Execution Vulnerabilities (CVE-2020-11651 and CVE-2020-11652)

SaltStack Remote Command Execution Vulnerabilities (CVE-2020-11651 and CVE-2020-11652)

Updated on 2025-01-07 GMT+08:00

Security researchers discovered two serious vulnerabilities in SaltStack's products. SaltStack provides a set of product offerings written in Python for automatic C/S O&M. One of the two discovered vulnerabilities is authentication bypass vulnerabilities (CVE-2020-11651), and the other is directory traversal vulnerability (CVE-2020-11652). Attackers can exploit the vulnerabilities to remotely execute commands, read any files on the server, and obtain sensitive information.

If you are a SaltStack user, check your system and implement timely security hardening.
