It was found that the fix for CVE-2021-41773 in Apache HTTP Server 2.4.50 was insufficient. An attacker could use a path traversal attack to map URLs to files outside the directories configured by Alias-like directives. If files outside of these directories are not protected by the usual default configuration "require all denied", these requests can succeed. If CGI scripts are also enabled for these aliased pathes, this could allow for remote code execution. This issue only affects Apache 2.4.49 and Apache 2.4.50 and not earlier versions. • https://www.exploit-db.com/exploits/50406 https://www.exploit-db.com/exploits/50446 https://www.exploit-db.com/exploits/50512 https://github.com/andrea-mattioli/apache-exploit-CVE-2021-42013 https://github.com/asaotomo/CVE-2021-42013-Apache-RCE-Poc-Exp https://github.com/BassoNicolas/CVE-2021-42013 https://github.com/TheLastVvV/CVE-2021-42013 https://github.com/rafifdna/CVE-2021-42013 https://github.com/rnsss/CVE-2021-42013 https://github.com/LayarKacaSiber/CVE-2021-42013 • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •

A flaw was found in a change made to path normalization in Apache HTTP Server 2.4.49. An attacker could use a path traversal attack to map URLs to files outside the directories configured by Alias-like directives. If files outside of these directories are not protected by the usual default configuration "require all denied", these requests can succeed. If CGI scripts are also enabled for these aliased pathes, this could allow for remote code execution. This issue is known to be exploited in the wild. • https://www.exploit-db.com/exploits/50512 https://www.exploit-db.com/exploits/50383 https://github.com/blasty/CVE-2021-41773 https://github.com/thehackersbrain/CVE-2021-41773 https://github.com/iilegacyyii/PoC-CVE-2021-41773 https://github.com/lorddemon/CVE-2021-41773-PoC https://github.com/0xRar/CVE-2021-41773 https://github.com/ZephrFish/CVE-2021-41773-PoC https://github.com/itsecurityco/CVE-2021-41773 https://github.com/BlueTeamSteve/CVE-2021-41773 https://github. • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •

While fuzzing the 2.4.49 httpd, a new null pointer dereference was detected during HTTP/2 request processing, allowing an external source to DoS the server. This requires a specially crafted request. The vulnerability was recently introduced in version 2.4.49. No exploit is known to the project. Mientras se realizaba el fuzzing del httpd versión 2.4.49, se detectó una nueva desreferencia de puntero null durante el procesamiento de peticiones HTTP/2, permitiendo a una fuente externa hacer DoS al servidor. • http://www.openwall.com/lists/oss-security/2021/10/05/1 https://httpd.apache.org/security/vulnerabilities_24.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/DSM6UWQICBJ2TU727RENU3HBKEAFLT6T https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/EUVJVRJRBW5QVX4OY3NOHZDQ3B3YOTSG https://security.gentoo.org/glsa/202208-20 https://security.netapp.com/advisory/ntap-20211029-0009 https://tools.cisco.com/security/center/content/CiscoSecurityAd • CWE-476: NULL Pointer Dereference •

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 •
