RSA Authentication Agent for Microsoft Windows 7.4.6 and earlier

Summary

RSA Authentication Agent 7.4.7 for Microsoft Windows contains remediation of the issue where search paths in certain cases are open and could be exploited by malicious users to compromise the affected system.

Details

This vulnerability exists due to a misconfigured executable path. A registry entry containing the path of an agent executable is not quoted. This allows an adversary to create a malicious program in the search path and get the agent service to load this malicious executable instead of the intended one.

Resolution

RSA Authentication Agent 7.4.7 for Microsoft Windows release contains resolutions to these vulnerabilities.

The primary support of RSA Authentication Agent for Microsoft Windows (all versions) ended in June 2024, and the component is now replaced by a modern component RSA MFA Agent for Microsoft Windows, which supports RSA Cloud Authentication Service, RSA Authentication Manager, and hybrid scenarios. RSA MFA Agent for Microsoft Windows does not have the preceding vulnerability.

RSA recommends all customers upgrade to RSA Authentication Agent 7.4.7 for Microsoft Windows and upgrade to the latest version of RSA MFA Agent for Microsoft Windows at the earliest opportunity.
