Synopsis

PHP 7.4.x < 7.4.5 Multiple Vulnerabilities

Description

According to its banner, the version of PHP running on the remote web server is prior to 7.2.30, 7.3.x prior to 7.3.17, or 7.4.x prior to 7.4.5. It is, therefore, affected by multiple vulnerabilities:

 - An out-of-bounds read error exists in urldecode() due to improper data validation checks. An attacker can exploit this, by inserting negative hex values to leak values that are found in the memory before the array. (CVE-2020-7067)

 - A NULL byte injection vulnerability exists in shell_exec() and the backtick operator due to improper data sanitization.

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 7.4.5 or later.
