An issue was discovered in SaltStack Salt before 3002.5. The salt-apis ssh client is vulnerable to a shell injection by including ProxyCommand in an argument, or via ssh_options provided in an API request.

Weakness

The product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component.
