The version of httpd installed on the remote host is prior to 2.4.66-1. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2025-3099 advisory.

    An integer overflow in the case of failed ACME certificate renewal leads, after a number of failures (~30     days in default configurations), to the backoff timer becoming 0. Attempts to renew the certificate then     are repeated without delays until it succeeds.

    This issue affects Apache HTTP Server: from 2.4.30 before 2.4.66.

    Users are recommended to upgrade to version 2.4.66, which fixes the issue. (CVE-2025-55753)

    Apache HTTP Server 2.4.65 and earlier with Server Side Includes (SSI) enabled and mod_cgid (but not     mod_cgi) passes the shell-escaped query string to #exec cmd=... directives. (CVE-2025-58098)

    Improper Neutralization of Escape, Meta, or Control Sequences vulnerability in Apache HTTP Server through     environment variables set via the Apache configuration unexpectedly superseding variables calculated by     the server for CGI programs.

    This issue affects Apache HTTP Server from 2.4.0 through 2.4.65.

    Users are recommended to upgrade to version 2.4.66 which fixes the issue. (CVE-2025-65082)

    mod_userdir+suexec bypass via AllowOverride FileInfo vulnerability in Apache HTTP Server. Users with     access to use the RequestHeader directive in htaccess can cause some CGI scripts to run under an     unexpected userid. (CVE-2025-66200)
