What is SaltStack Salt?

SaltStack Salt is an open-source configuration management and orchestration tool which is designed to automate complex system management and monitoring tasks. Employing a centralized server communicating with nodes (clients) via a secure channel, Salt is essential for many administrators for its ability to execute commands across many systems simultaneously.

Details of CVE-2020-16846

The Critical-rated CVE-2020-16846 concerns a shell injection vulnerability found in SaltStack Salt versions up to 3002. The flaw arises when maliciously crafted web requests are sent to the Salt API. Significantly, this vulnerability requires the SSH client to be enabled, which can result in remote code execution.

This kind of vulnerability is particularly severe because it allows attackers to execute arbitrary code remotely on the server hosting the Salt API. The CVSS score of 9.8 underscores its severity, underlining the potential for significant damage and exploitation.

Implications for Your Systems

With the power to execute arbitrary commands, an attacker exploiting this vulnerability could conduct a range of malicious activities. These activities might include stealing sensitive data, installing malware, or taking over the entire system. The security of your infrastructure and the integrity of your data could be compromised, leading to potential business disruptions and financial losses.

How to Protect Your Systems

Addressing CVE-2020-16846 effectively requires immediate action:
