The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2020:1112 advisory.
php: Reflected XSS vulnerability on PHAR 403 and 404 error pages (CVE-2018-10547)
php: Reflected XSS on PHAR 404 page (CVE-2018-5712)
php: Stack-based buffer under-read in php_stream_url_wrap_http_ex() in http_fopen_wrapper.c when parsing HTTP response (CVE-2018-7584)
php: Out-of-bounds read in base64_decode_xmlrpc in ext/xmlrpc/libxmlrpc/base64.c (CVE-2019-9024)
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
