"The remote web server appears to be running a version of Apache that

This version is vulnerable to a local buffer overflow in the get_tag()

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
