Summary

Acunetix 360 identified that the target web server is disclosing the mod_ssl version in its HTTP response. This information might help an attacker gain a greater understanding of the systems in use and potentially develop further attacks targeted at the specific version of mod_ssl.

Impact

An attacker might use the disclosed information to harvest specific security vulnerabilities for the version identified.

LoadModule headers_module modules/mod_headers.so
    
After headers_module is loaded, edit or include the following lines of config in the httpd.conf
