Name of the Vulnerable Software and Affected Versions: Emissary version 5.9.0

Description: The issue allows for a CSRF attack, which can result in injecting arbitrary Ruby code via the CONSOLE COMMAND STRING parameter. This can lead to an eval call, potentially allowing an attacker to execute malicious code.

Recommendations: For Emissary version 5.9.0, as a temporary workaround, consider restricting access to the ConsoleAction component to minimize the risk of exploitation. Avoid using the CONSOLE COMMAND STRING parameter in the affected component until the issue is resolved.
