CVSS: 5.3EPSS: 0%CPEs: 7EXPL: 1CVE-2021-21707 – Special characters break path parsing in XML functions
https://notcve.org/view.php?id=CVE-2021-21707
In PHP versions 7.3.x below 7.3.33, 7.4.x below 7.4.26 and 8.0.x below 8.0.13, certain XML parsing functions, like simplexml_load_file(), URL-decode the filename passed to them. If that filename contains URL-encoded NUL character, this may cause the function to interpret this as the end of the filename, thus interpreting the filename differently from what the user intended, which may lead it to reading a different file than intended. En PHP versiones 7.3.x anteriores a 7.3.33, 7.4.x anteriores a 7.4.26 y 8.0.x anteriores a 8.0.13, determinadas funciones de análisis de XML, como simplexml_load_file(), decodifican el nombre de archivo que les es pasado. Si ese nombre de archivo contiene un carácter NUL codificado en la URL, esto puede causar que la función lo interprete como el final del nombre de archivo, interpretando así el nombre de archivo de forma diferente a la que el usuario pretendía, lo que puede conllevar a una lectura de un archivo diferente al deseado A flaw was found in php. The main cause of this vulnerability is improper input validation while parsing an Extensible Markup Language(XML) entity. • https://bugs.php.net/bug.php?id=79971 https://lists.debian.org/debian-lts-announce/2022/12/msg00030.html https://security.netapp.com/advisory/ntap-20211223-0005 https://www.debian.org/security/2022/dsa-5082 https://www.tenable.com/security/tns-2022-09 https://access.redhat.com/security/cve/CVE-2021-21707 https://bugzilla.redhat.com/show_bug.cgi?id=2026045 • CWE-20: Improper Input Validation CWE-159: Improper Handling of Invalid Use of Special Elements •
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 •

sshd in OpenSSH 6.2 through 8.x before 8.8, when certain non-default configurations are used, allows privilege escalation because supplemental groups are not initialized as expected. Helper programs for AuthorizedKeysCommand and AuthorizedPrincipalsCommand may run with privileges associated with group memberships of the sshd process, if the configuration specifies running the command as a different user. sshd en OpenSSH versiones 6.2 hasta 8.x anteriores a 8.8, cuando son usadas determinadas configuraciones no predeterminadas, permite una escalada de privilegios porque los grupos complementarios no son inicializados como se espera. Los programas de ayuda para AuthorizedKeysCommand y AuthorizedPrincipalsCommand pueden ejecutarse con privilegios asociados a la pertenencia a grupos del proceso sshd, si la configuración especifica la ejecución del comando como un usuario diferente A flaw was found in OpenSSH. Helper programs for AuthorizedKeysCommand and AuthorizedPrincipalsCommand may run with privileges associated with group memberships of the sshd process, if the configuration specifies running the command as a different user. Depending on system configuration, inherited groups may allow AuthorizedKeysCommand/AuthorizedPrincipalsCommand helper programs to gain unintended privileges, potentially leading to local privilege escalation. • https://bugzilla.suse.com/show_bug.cgi?id=1190975 https://lists.debian.org/debian-lts-announce/2023/12/msg00017.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/6XJIONMHMKZDTMH6BQR5TNLF2WDCGWED https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/KVI7RWM2JLNMWTOFK6BDUSGNOIPZYPUT https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/W44V2PFQH5YLRN6ZJTVRKAD7CU6CYYET https://security.netapp.com/advisory/ntap-20211014& • CWE-273: Improper Check for Dropped Privileges •
