"The version of httpd installed on the remote CBL Mariner 2.0 host is prior to tested version. It is, therefore, affected
by a vulnerability as referenced in the CVE-2024-39884 advisory.

  - A regression in the core of Apache HTTP Server 2.4.60 ignores some use of the legacy content-type based
    configuration of handlers. AddType and similar configuration, under some circumstances where files are
    requested indirectly, result in source code disclosure of local content. For example, PHP scripts May be
    served instead of interpreted. Users are recommended to upgrade to version 2.4.61, which fixes this issue.
