PHP 7.2.x < 7.2.30 Multiple Vulnerabilities

high Nessus Plugin ID 135926

Synopsis

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

Description

According to its self-reported version number, the version of PHP running on the remote web server is 7.2.x prior to 7.2.30. 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.
- A NULL byte injection vulnerability exists in shell_exec() and the backtick operator due to improper data sanitization.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to PHP version 7.2.30 or later.
