CVSS: 7.8EPSS: 0%CPEs: 11EXPL: 1CVE-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. This vulnerability is hard to exploit as the attack needs to escape the FPM sandbox mechanism. When a complete attack is achieved it may lead to risk for confidentiality, data integrity, and system availability. • 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 •

Vulnerability in the Java SE, Oracle GraalVM Enterprise Edition product of Oracle Java SE (component: JSSE). Supported versions that are affected are Java SE: 7u311, 8u301, 11.0.12, 17; Oracle GraalVM Enterprise Edition: 20.3.3 and 21.2.0. Difficult to exploit vulnerability allows unauthenticated attacker with network access via TLS to compromise Java SE, Oracle GraalVM Enterprise Edition. Successful attacks of this vulnerability can result in unauthorized read access to a subset of Java SE, Oracle GraalVM Enterprise Edition accessible data. Note: This vulnerability applies to Java deployments, typically in clients running sandboxed Java Web Start applications or sandboxed Java applets, that load and run untrusted code (e.g., code that comes from the internet) and rely on the Java sandbox for security. • https://lists.debian.org/debian-lts-announce/2021/11/msg00008.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/6EUURAQOIJYFZHQ7DFZCO6IKDPIAWTNK https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/GTYZWIXDFUV2H57YQZJWPOD3BC3I3EIQ https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/GXTUWAWXVU37GRNIG4TPMA47THO6VAE6 https://security.gentoo.org/glsa/202209-05 https://security.netapp.com/advisory/ntap-20211022-0004 h • CWE-203: Observable Discrepancy •
