CVSS: 8.8EPSS: 96%CPEs: 68EXPL: 3CVE-2019-0211 – Apache HTTP Server Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2019-0211
In Apache HTTP Server 2.4 releases 2.4.17 to 2.4.38, with MPM event, worker or prefork, code executing in less-privileged child processes or threads (including scripts executed by an in-process scripting interpreter) could execute arbitrary code with the privileges of the parent process (usually root) by manipulating the scoreboard. Non-Unix systems are not affected. En Apache HTTP Server 2.4, versiones 2.4.17 a 2.4.38, con el evento MPM, worker o prefork, el código ejecutándose en procesos hijo (o hilos) menos privilegiados (incluyendo scripts ejecutados por un intérprete de scripts en proceso) podría ejecutar código arbitrario con los privilegios del proceso padre (normalmente root) manipulando el marcador. Los sistemas que no son Unix no se ven afectados. A flaw was found in Apache where code executing in a less-privileged child process or thread could execute arbitrary code with the privilege of the parent process (usually root). • https://www.exploit-db.com/exploits/46676 http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00051.html http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00061.html http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00084.html http://packetstormsecurity.com/files/152386/Apache-2.4.38-Root-Privilege-Escalation.html http://packetstormsecurity.com/files/152415/Slackware-Security-Advisory-httpd-Updates.html http://packetstormsecurity.com/files/152441/CARPE-DIEM-Apache-2.4.x • CWE-250: Execution with Unnecessary Privileges CWE-416: Use After Free •

https://notcve.org/view.php?id=CVE-2018-17189
In Apache HTTP server versions 2.4.37 and prior, by sending request bodies in a slow loris way to plain resources, the h2 stream for that request unnecessarily occupied a server thread cleaning up that incoming data. This affects only HTTP/2 (mod_http2) connections. En Apache HTTP Server, en sus versiones 2.4.37 y anteriores, mediante el envío de cuerpos de respuesta mediante la técnica del "slow loris" a recursos planos, la transmisión h2 para esa petición ocupó de forma innecesaria un hilo de servidor que limpiaba tales datos entrantes. Esto afecta solo a las conexiones HTTP/2 (mod_http2). • http://www.securityfocus.com/bid/106685 https://access.redhat.com/errata/RHSA-2019:3932 https://access.redhat.com/errata/RHSA-2019:3933 https://access.redhat.com/errata/RHSA-2019:3935 https://access.redhat.com/errata/RHSA-2019:4126 https://httpd.apache.org/security/vulnerabilities_24.html https://lists.apache.org/thread.html/56c2e7cc9deb1c12a843d0dc251ea7fd3e7e80293cde02fcd65286ba%40%3Ccvs.httpd.apache.org%3E https://lists.apache.org/thread.html/84a3714f0878781f6ed84473d1a503d2cc382277e100450209231830%40%3Ccvs.httpd.apache • CWE-400: Uncontrolled Resource Consumption •
CVSS: 7.5EPSS: 0%CPEs: 10EXPL: 0CVE-2018-17199 – httpd: mod_session_cookie does not respect expiry time
https://notcve.org/view.php?id=CVE-2018-17199
In Apache HTTP Server 2.4 release 2.4.37 and prior, mod_session checks the session expiry time before decoding the session. This causes session expiry time to be ignored for mod_session_cookie sessions since the expiry time is loaded when the session is decoded. En Apache HTTP Server 2.4, en sus distribuciones 2.4.37 y anteriores, mod_session comprueba el tiempo de caducidad de la sesión antes de descodificarla. Esto provoca que se ignore el tiempo de caducidad de la sesión para sesiones mod_session_cookie, debido a que el tiempo de caducidad se carga cuando la sesión está descodificada. • http://www.securityfocus.com/bid/106742 https://access.redhat.com/errata/RHSA-2019:3932 https://access.redhat.com/errata/RHSA-2019:3933 https://access.redhat.com/errata/RHSA-2019:3935 https://access.redhat.com/errata/RHSA-2019:4126 https://httpd.apache.org/security/vulnerabilities_24.html https://lists.apache.org/thread.html/56c2e7cc9deb1c12a843d0dc251ea7fd3e7e80293cde02fcd65286ba%40%3Ccvs.httpd.apache.org%3E https://lists.apache.org/thread.html/84a3714f0878781f6ed84473d1a503d2cc382277e100450209231830%40%3Ccvs.httpd.apache • CWE-384: Session Fixation CWE-613: Insufficient Session Expiration •

https://notcve.org/view.php?id=CVE-2018-11763
In Apache HTTP Server 2.4.17 to 2.4.34, by sending continuous, large SETTINGS frames a client can occupy a connection, server thread and CPU time without any connection timeout coming to effect. This affects only HTTP/2 connections. A possible mitigation is to not enable the h2 protocol. En Apache HTTP Server, de la versión 2.4.17 a la 2.4.34, mediante el envío continuo de tramas SETTINGS grandes, un cliente puede ocupar una conexión, hilo del servidor y tiempo de CPU sin que se active ningún agotamiento del tiempo de conexión. Esto solo afecta a las conexiones HTTP/2. • http://lists.opensuse.org/opensuse-security-announce/2019-06/msg00030.html http://lists.opensuse.org/opensuse-security-announce/2019-07/msg00056.html http://www.securityfocus.com/bid/105414 http://www.securitytracker.com/id/1041713 https://access.redhat.com/errata/RHSA-2018:3558 https://access.redhat.com/errata/RHSA-2019:0366 https://access.redhat.com/errata/RHSA-2019:0367 https://httpd.apache.org/security/vulnerabilities_24.html https://lists.apache.org/thread.html/56c2e7cc9deb1c12a843d0dc251ea7f • CWE-20: Improper Input Validation •

https://notcve.org/view.php?id=CVE-2016-4975
Possible CRLF injection allowing HTTP response splitting attacks for sites which use mod_userdir. This issue was mitigated by changes made in 2.4.25 and 2.2.32 which prohibit CR or LF injection into the "Location" or other outbound header key or value. Fixed in Apache HTTP Server 2.4.25 (Affected 2.4.1-2.4.23). Fixed in Apache HTTP Server 2.2.32 (Affected 2.2.0-2.2.31). Posible inyección CRLF que permite ataques de separación de respuesta HTTP para los sitios que emplean mod_userdir. • http://www.securityfocus.com/bid/105093 https://httpd.apache.org/security/vulnerabilities_22.html#CVE-2016-4975 https://httpd.apache.org/security/vulnerabilities_24.html#CVE-2016-4975 https://lists.apache.org/thread.html/56c2e7cc9deb1c12a843d0dc251ea7fd3e7e80293cde02fcd65286ba%40%3Ccvs.httpd.apache.org%3E https://lists.apache.org/thread.html/84a3714f0878781f6ed84473d1a503d2cc382277e100450209231830%40%3Ccvs.httpd.apache.org%3E https://lists.apache.org/thread.html/8d63cb8e9100f28a99429b4328e4e7cebce861d5772ac9863ba2ae6f%40%3Ccvs.httpd.apache.org%3E https&# • CWE-93: Improper Neutralization of CRLF Sequences ('CRLF Injection') CWE-113: Improper Neutralization of CRLF Sequences in HTTP Headers ('HTTP Request/Response Splitting') •
