"According to the versions of the httpd packages installed, the EulerOS Virtualization installation on the remote host is
affected by the following vulnerabilities :

    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)

    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)

    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.(CVE-2025-65082)

Tenable has extracted the preceding description block directly from the EulerOS Virtualization httpd security advisory.

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