PHP < 7.1.33 / 7.2.x < 7.2.24 / 7.3.x < 7.3.11 Remote Code Execution Vulnerability.

critical Nessus Plugin ID 130276

Synopsis

An application installed on the remote host is affected by a 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.

Solution

Upgrade to PHP version 7.3.11 or later.
