The user may also be interested in "disable_functions bypass" exploits. I recall an exploit for PHP 7.1-7.3 that bypasses disable_functions using the json serializer. That might be relevant. I'll open the exploit-db entry for that. I already opened it partially. Let's open it fully. is a complex exploit that bypasses disable_functions. It might be relevant, but it's for PHP 7.1-7.3, not specifically 7.4. However, similar techniques might work on 7.4. : An object or array is allocated via

Memory corruption exploits are rarely 100% reliable. Unsuccessful exploit attempts frequently cause the PHP-FPM or Apache worker processes to crash, resulting in SIGSEGV (Segmentation Fault) entries in system error logs ( /var/log/syslog or /var/log/apache2/error.log ). That might be relevant

If data structures must be passed over the wire, utilize safer text-based formats such as JSON ( json_encode() and json_decode() ), which do not invoke the engine's complex object instantiation workflows. 4.
