https://notcve.org/view.php?id=CVE-2019-0217
In Apache HTTP Server 2.4 release 2.4.38 and prior, a race condition in mod_auth_digest when running in a threaded server could allow a user with valid credentials to authenticate using another username, bypassing configured access control restrictions. En Apache HTTP Server 2.4 versión 2.4.38 y anteriores, una condición de carrera en mod_auth_digest cuando se ejecuta en un servidor multihilo podría permitir a un usuario con credenciales válidas autenticarse usando otro nombre de usuario, evitando las restricciones de control de acceso configuradas. A race condition was found in mod_auth_digest when the web server was running in a threaded MPM configuration. It could allow a user with valid credentials to authenticate using another username, bypassing configured access control restrictions. • 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://www.openwall.com/lists/oss-security/2019/04/02/5 http://www.securityfocus.com/bid/107668 https://access.redhat.com/errata/RHSA-2019:2343 https://access.redhat.com/errata/RHSA-2019:3436 https://access.redhat.com/errata/RHSA-2019:3932 https://access.red • CWE-284: Improper Access Control CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •

A vulnerability was found in Apache HTTP Server 2.4.0 to 2.4.38. When the path component of a request URL contains multiple consecutive slashes ('/'), directives such as LocationMatch and RewriteRule must account for duplicates in regular expressions while other aspects of the servers processing will implicitly collapse them. Se descubrió una vulnerabilidad en Apache HTTP Server 2.4.0 hasta 2.4.38. Cuando el componente del recorrido de la solicitud de la URL contiene múltiples barras diagonales consecutivas ('/'), como por ejemplo LocationMatch y RewriteRule debe tener en cuenta los duplicados en las expresiones regulares que otros aspectos del procesamiento de los servidores los colapsarán implícitamente. • 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://www.openwall.com/lists/oss-security/2019/04/02/6 http://www.securityfocus.com/bid/107670 https://access.redhat.com/errata/RHSA-2019:2343 https://access.redhat.com/errata/RHSA-2019:3436 https://access.redhat.com/errata/RHSA-2019:4126 https://access.red • CWE-41: Improper Resolution of Path Equivalence CWE-706: Use of Incorrectly-Resolved Name or Reference •
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 •

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).

CVSS: 7.5EPSS: 95%CPEs: 11EXPL: 0CVE-2018-1303 – httpd: Out of bounds read in mod_cache_socache can allow a remote attacker to cause DoS
https://notcve.org/view.php?id=CVE-2018-1303
A specially crafted HTTP request header could have crashed the Apache HTTP Server prior to version 2.4.30 due to an out of bound read while preparing data to be cached in shared memory. It could be used as a Denial of Service attack against users of mod_cache_socache. The vulnerability is considered as low risk since mod_cache_socache is not widely used, mod_cache_disk is not concerned by this vulnerability. Una cabecera HTTP especialmente manipulada podría haber provocado el cierre inesperado del servidor Apache HTTP en versiones anteriores a la 2.4.30, debido a una lectura fuera de límites mientras se preparan los datos que se van a almacenar en la memoria caché compartida. Esto se podría utilizar como ataque de denegación de servicio (DoS) contra usuarios de mod_cache_socache. • http://www.openwall.com/lists/oss-security/2018/03/24/3 http://www.securityfocus.com/bid/103522 http://www.securitytracker.com/id/1040572 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/56c2e7cc9deb1c12a843d0dc251ea7fd3e7e80293cde02fcd65286ba%40%3Ccvs.httpd.apache.org%3E https://lists.apache.org/thread.ht • CWE-125: Out-of-bounds Read •
