PHP: Arbitrary code execution

PHP: Arbitrary code execution A vulnerability in PHP might allow an attacker to execute arbitrary code. php 2019-10-25 2019-11-19 698452 remote 7.1.33 7.2.24 7.3.11 5.6.40-r7 7.1.33 7.2.24 7.3.11 5.6.40-r7

PHP is an open source general-purpose scripting language that is especially suited for web development.

A underflow in env_path_info in PHP-FPM under certain configurations can be exploited to gain remote code execution.

A remote attacker, by sending special crafted HTTP requests, could possibly execute arbitrary code with the privileges of the process, or cause a Denial of Service condition.

If patching is not feasible, the suggested workaround is to include checks to verify whether or not a file exists before passing to PHP.
