CVE-2021-21703 – PHP-FPM memory access in root process leading to privilege escalation
https://notcve.org/view.php?id=CVE-2021-21703
In PHP versions 7.3.x up to and including 7.3.31, 7.4.x below 7.4.25 and 8.0.x below 8.0.12, when running PHP FPM SAPI with main FPM daemon process running as root and child worker processes running as lower-privileged users, it is possible for the child processes to access memory shared with the main process and write to it, modifying it in a way that would cause the root process to conduct invalid memory reads and writes, which can be used to escalate privileges from local unprivileged user to the root user. En PHP versiones 7.3.x hasta 7.3.31 incluyéndola, versiones 7.4.x y por debajo de 7.4.25 y versiones 8.0.x por debajo de 8.0. 12, cuando es ejecutado PHP FPM SAPI con el proceso demonio FPM principal ejecutado como root y los procesos worker hijos ejecutados como usuarios menos privilegiados, es posible que los procesos hijos accedan a la memoria compartida con el proceso principal y escriban en ella, modificándola de forma que causaría que el proceso root realizara lecturas y escrituras de memoria no válidas, que puede ser usado para escalar los privilegios del usuario local sin privilegios al usuario root php-fpm has a vulnerability which may lead to local privilege escalation. • http://www.openwall.com/lists/oss-security/2021/10/26/7 https://bugs.php.net/bug.php?id=81026 https://lists.debian.org/debian-lts-announce/2021/10/msg00021.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/6PZVLICZUJMXOGWOUWSBAEGIVTF6Y6V3 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/JO5RA6YOBGGGKLIA6F6BQRZDDECF5L3R https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/PBM3KKB3RY2YPOKNMC4HIH7I • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-284: Improper Access Control CWE-787: Out-of-bounds Write •
