What is SaltStack Salt?

SaltStack Salt is an open-source configuration management and orchestration tool. It is widely used to automate server setup, management, and maintenance tasks across large clusters of servers. Salt is especially popular in environments where managing complex infrastructures and fast-paced deployments are crucial.

Details of the CVE-2021-25284 Vulnerability

This vulnerability is rooted in "salt.modules.cmdmod", a module within Salt that allows for the execution of command lines and scripts. In versions prior to 3002.5, sensitive data such as credentials could be captured in log entries at the 'info' or 'error' log level. Access to such logs by unauthorized users or malware could lead to data leakage, which is a significant security risk.

Impact and Risks

The improper handling of logged information poses a special risk to corporations and IT personnel relying on confidentiality and security of their system's configurations and operations. Unauthorized access to these logs could enable attackers to gain further control of affected systems. The medium severity rating (4.4) emphasizes the need for prompt and effective action.
