tag_summary = "The remote web server appears to be running a version of Apache that is older
than version 1.3.33.

This version is vulnerable to a local buffer overflow in the get_tag()
function of the module 'mod_include' when a specially crafted document 
with malformed server-side includes is requested though an HTTP session.

Successful exploitation can lead to execution of arbitrary code with 
escalated privileges, but requires that server-side includes (SSI) is enabled.";

tag_solution = "Disable SSI or upgrade to a newer version when available.";
