"The version of Apache httpd installed on the remote host is prior to 2.4.69. It is, therefore, affected by multiple
vulnerabilities as referenced in the 2.4.69 advisory.

  - Improper Privilege Management vulnerability in Apache HTTP Server's mod_ssl via SSLRequire and file-
    related expressions. This issue affects Apache HTTP Server: from 2.4.0 through 2.4.68. (CVE-2026-59797)

  - Deployment of wrong handler vulnerability in Apache HTTP Server allows the target of some internal
    redirects from CGI programs to also be treated as CGI and executed. The target must already be in a
    directory enabled for CGI and have no other extension understood by mod_mime. This issue affects Apache
    HTTP Server: from 2.4.60 through 2.4.68. (CVE-2026-42356)

  - A memory calculation bug in mod_dav in Apache httpd 2.4.67 and earlier allows an attacker with permission
    to create WebDAV locks to crash server child processes. Users are recommended to upgrade to version
    2.4.69, which fixes this issue (CVE-2026-42528)

  - NULL Pointer Dereference vulnerability in Apache HTTP Servers mod_heartmonitor over unicast listener. This
    issue affects Apache HTTP Server: from 2.4.0 through 2.4.68. (CVE-2026-46729)

  - Exposure of Sensitive Information to an Unauthorized Actor vulnerability in Apache HTTP Server's
    mod_session_cookie module. When SessionCookieRemove changes across internal redirects, the session cookie
    may still be passed to a backend server. This issue affects Apache HTTP Server: from 2.4.0 through 2.4.68.
    (CVE-2026-47360)

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