Avalduse meetod PHP t\u00f5lgendis, mis v\u00f5imaldab \u00fcletada php.ini direttiivide disable_functions ja teiste seadistuste kehtestatud piiranguid. Meenutame, et direttiiv disable_functions v\u00f5imaldab keelata teatud sisemiste funktsioonide kasutamise skriptides, n\u00e4iteks v\u00f5ib keelata «system, exec, passthru, popen, proc_open ja shell_exec» v\u00e4liste programmide kutsete blokeerimiseks v\u00f5i fopen failide avamise keelamiseks. <\/p>\n

Tuleb m\u00e4rkida, et ettepanekus kasutatav haavatavus on teadaolev, millest PHP arendajatele teatati enam kui 10 aastat tagasi, kuid nad pidasid seda ebaoluliseks probleemiks, mis ei m\u00f5juta turvalisust. Pakutud r\u00fcnnakumeetod p\u00f5hineb protsessi m\u00e4lu parameetrite v\u00e4\u00e4rtuste muutmisel ja see t\u00f6\u00f6tab k\u00f5igis aktuaalsetes PHP versioonides, alates PHP 7.0 (r\u00fcnnak on v\u00f5imalik ka PHP 5.x versioonides, kuid selleks on vajalik muutuste tegemine eksploitis). Eksploit on testitud erinevates Debian, Ubuntu, CentOS ja FreeBSD konfiguratsioonides PHP cli, fpm ja apache2 moodulina.
