Bug vulnerability class | Weak Encryption |
Bug description | The remote host is running an Apache web server. The Apache Software Foundation has reported an issue that may occur when the SSLCipherSuite directive is used to upgrade a cipher suite. Particular sequences of per-directory renegotiations may cause this condition to occur, resulting in a weaker cipher suite being used in place of the upgraded one. |
Bug solution | If the web server is not used it should be de-installed or de-activated. Install the newest patch or bugfix to solve the problem or upgrade to the latest software version which is not vulnerable anymore. To make it harder to find the server the daemon could be configured to listen at another port (e.g. 8081). Alternation of the application banner can confuse an attacker and let him determine the wrong software. Additionally limit unwanted connections and communications with firewalling. |
