According to its banner, the version of PHP running on the remote web server is 7.2.x prior to 7.2.1. It is, therefore, affected by the following vulnerabilities :
A denial of service (DoS) vulnerability exists in the imagecreatefromgif and imagecreatefromstring functions of the gd_gif_in.c script within GD Graphics Library (libgd) due to an integer signedness error. An unauthenticated, remote attacker can exploit this issue, via a crafted GIF file, to cause the applicaiton to stop responding. (CVE-2018-5711)
A cross-site scripting (XSS) vulnerability exists due to improper validation of .phar file before returning it to users. An unauthenticated, remote attacker can exploit this, by convincing a user to click a specially crafted URL, to execute arbitrary script code in a user’s browser session. (CVE-2018-5712)
A denial of service (DoS) vulnerability exists in the ext/standard/http_fopen_wrapper.c script due to http_header_value possibly being a NULL value in an atoi call. An unauthenticated, remote attacker can exploit this issue, via a specifically crafted HTTP response, to cause the application to stop responding. (CVE-2018-14884)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
