A connection is vulnerable if the server accepts RSA_EXPORT cipher suites and the client either offers an RSA_EXPORT suite or is using a version of OpenSSL that is vulnerable to CVE-2015-0204.

有没有工具是测试 server 端的呢?

@cmkpl
What should I do?
If you run a web server, you should disable support for any export suites. However, instead of simply excluding RSA export cipher suites, we encourage administrators to disable support for all known insecure ciphers (e.g., there are export cipher suites protocols other than RSA) and enable forward secrecy. Mozilla has published a guide and SSL Configuration Generator, which will generate known good configurations for common servers.

You can check whether a website supports RSA_EXPORT suites using the SSL FREAK Check. However, we also encourage administrators to check their overall site configuration using the Qualys SSL Labs' SSL Server Test, which will identify other potential misconfigurations.
