Synopsis

The version of PHP running on the remote web server is affected by multiple vulnerabilities.

Description

According to its banner, the version of PHP running on the remote web server is either 7.2.x prior to 7.2.27, 7.3.x prior to 7.3.14, or 7.4.x prior to 7.4.2. It is, therefore, affected by multiple vulnerabilities:
