"The version of PHP installed on the remote host is prior to 8.1.29. It is, therefore, affected by multiple
vulnerabilities as referenced in the Version 8.1.29 advisory.

  - sapi/cgi/cgi_main.c in PHP before 5.3.12 and 5.4.x before 5.4.2, when configured as a CGI script (aka php-
    cgi), does not properly handle query strings that lack an = (equals sign) character, which allows remote
    attackers to execute arbitrary code by placing command-line options in the query string, related to lack
    of skipping a certain php_getopt for the 'd' case. (CVE-2012-1823)

  - In PHP versions 8.1.* before 8.1.28, 8.2.* before 8.2.18, 8.3.* before 8.3.5, when using proc_open()
    command with array syntax, due to insufficient escaping, if the arguments of the executed command are
    controlled by a malicious user, the user can supply arguments that would execute arbitrary commands in
    Windows shell. (CVE-2024-1874)

  - In PHP versions 8.1.* before 8.1.29, 8.2.* before 8.2.20, 8.3.* before 8.3.8, when using Apache and PHP-
    CGI on Windows, if the system is set up to use certain code pages, Windows may use Best-Fit behavior to
    replace characters in command line given to Win32 API functions. PHP CGI module may misinterpret those
    characters as PHP options, which may allow a malicious user to pass options to PHP binary being run, and
    thus reveal the source code of scripts, run arbitrary PHP code on the server, etc. (CVE-2024-4577)

  - In PHP versions 8.1.* before 8.1.29, 8.2.* before 8.2.20, 8.3.* before 8.3.8, due to a code logic error,
    filtering functions such as filter_var when validating URLs (FILTER_VALIDATE_URL) for certain types of
    URLs the function will result in invalid user information (username + password part of URLs) being treated
    as valid user information. This may lead to the downstream code accepting invalid URLs as valid and
    parsing them incorrectly. (CVE-2024-5458)

  - In PHP versions 8.1.* before 8.1.29, 8.2.* before 8.2.20, 8.3.* before 8.3.8, the fix for CVE-2024-1874
    does not work if the command name includes trailing spaces. Original issue: when using proc_open() command
    with array syntax, due to insufficient escaping, if the arguments of the executed command are controlled
    by a malicious user, the user can supply arguments that would execute arbitrary commands in Windows shell.
    (CVE-2024-5585)

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