"The version of IBM HTTP Server running on the remote host is affected by a vulnerability related to Apache HTTP Server.
In Apache HTTP Server 2.4 release 2.4.37 and prior, mod_session checks the session expiry time before decoding the
session. This causes session expiry time to be ignored for mod_session_cookie sessions since the expiry time is loaded
when the session is decoded.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
