PHP 7.3.x < 7.3.11 Remote Code Execution Vulnerability

Synopsis

PHP 7.3.x < 7.3.11 Remote Code Execution Vulnerability

Description

According to its banner, the version of PHP running on the remote web server is prior to 7.1.33, 7.2.x prior to 7.2.24, or 7.3.x prior to 7.3.11. It is, therefore, affected by a remote code execution vulnerability due to insufficient validation of user input. An unauthenticated, remote attacker can exploit this, by sending a specially crafted request, to cause the execution of arbitrary code by breaking the fastcgi_split_path_info directive.

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

Solution

Upgrade to PHP version 7.3.11 or later.
