A method for bypassing restrictions set in the PHP interpreter using the disable_functions directive and other php.ini settings has been published. Recall that the disable_functions directive allows the prohibition of certain internal functions in scripts, such as \"system, exec, passthru, popen, proc_open, and shell_exec\" to block the invocation of external programs, or fopen to prevent file opening. <\/p>\n

Notably, the proposed exploit utilizes a vulnerability that was reported to PHP developers more than 10 years ago, but they deemed it an insignificant issue that does not affect security. The suggested attack method is based on altering parameter values in the process memory and works in all current versions of PHP starting from PHP 7.0 (the attack is also possible in PHP 5.x, but that requires changes to the exploit). The exploit has been tested on various configurations of Debian, Ubuntu, CentOS, and FreeBSD with PHP in cli, fpm, and apache2 module forms.
