AS24-U1-000900 - The Apache web server must remove all export ciphers to protect the confidentiality and integrity of transmitted information.

Information

During the initial setup of a Transport Layer Security (TLS) connection to the Apache web server, the client sends a list of supported cipher suites in order of preference. The Apache web server will reply with the cipher suite it will use for communication from the client list. If an attacker can intercept the submission of cipher suites to the Apache web server and place, as the preferred cipher suite, a weak export suite, the encryption used for the session becomes easy for the attacker to break, often within minutes to hours.

Configuring the Apache server with only strong ciphersuites, denying or disabling weak ciphersuites, will prevent this vulnerability.

NOTE: Nessus has provided the target output to assist in reviewing the benchmark to ensure target compliance.

Solution

Update the cipher specification string for all enabled SSLCipherSuite directives to include !EXPORT.
