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: 7%CPEs: 8EXPL: 0CVE-2018-1333 – DoS for HTTP/2 connections by crafted requests
https://notcve.org/view.php?id=CVE-2018-1333
By specially crafting HTTP/2 requests, workers would be allocated 60 seconds longer than necessary, leading to worker exhaustion and a denial of service. Fixed in Apache HTTP Server 2.4.34 (Affected 2.4.18-2.4.30,2.4.33). Al manipular especialmente las peticiones HTTP/2, los trabajadores se asignarían 60 segundos más de los necesarios, lo que conduce a un agotamiento de los trabajadores y a una denegación de servicio (DoS). Esto se ha solucionado en Apache HTTP Server 2.4.34 (2.4.18 - 2.4.30, 2.4.33 afectadas). • http://www.securitytracker.com/id/1041402 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#CVE-2018-1333 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.o • CWE-400: Uncontrolled Resource Consumption •
CVSS: 9.8EPSS: 1%CPEs: 39EXPL: 0CVE-2018-1312 – httpd: Weak Digest auth nonce generation in mod_auth_digest
https://notcve.org/view.php?id=CVE-2018-1312
In Apache httpd 2.2.0 to 2.4.29, when generating an HTTP Digest authentication challenge, the nonce sent to prevent reply attacks was not correctly generated using a pseudo-random seed. In a cluster of servers using a common Digest authentication configuration, HTTP requests could be replayed across servers by an attacker without detection. En Apache httpd, en versiones desde la 2.2.0 hasta la 2.4.29, cuando se genera un desafío de autenticación HTTP Digest, el nonce enviado para evitar ataques replay no se generó correctamente empleando una semilla pseudoaleatoria. En un clúster de servidores, utilizando una configuración de autenticación Digest común, las peticiones HTTP se podrían reemplazar en los servidores por un atacante si que este sea detectado. • http://www.openwall.com/lists/oss-security/2018/03/24/7 http://www.securityfocus.com/bid/103524 http://www.securitytracker.com/id/1040571 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://access.redhat.com/errata/RHSA-2019:1898 https://httpd.apache.org/security/vulnerabilities_24.html https://lists.apache.org/thread.html/56c2e7cc9deb1c12a843d0dc251ea7fd3e7e80293cde02fcd65286ba%40%3Ccvs.httpd. • CWE-287: Improper Authentication CWE-305: Authentication Bypass by Primary Weakness •
CVSS: 7.4EPSS: 0%CPEs: 33EXPL: 0CVE-2017-12613 – apr: Out-of-bounds array deref in apr_time_exp*() functions
https://notcve.org/view.php?id=CVE-2017-12613
When apr_time_exp*() or apr_os_exp_time*() functions are invoked with an invalid month field value in Apache Portable Runtime APR 1.6.2 and prior, out of bounds memory may be accessed in converting this value to an apr_time_exp_t value, potentially revealing the contents of a different static heap value or resulting in program termination, and may represent an information disclosure or denial of service vulnerability to applications which call these APR functions with unvalidated external input. Cuando las funciones apr_time_exp*() o apr_os_exp_time*() se invocan con un valor del campo no válido en Apache Portable Runtime APR 1.6.2 y anteriores, se podría acceder a la memoria fuera de límites convirtiendo este valor en un valor apr_time_exp_t, revelando potencialmente el contenido de otro valor de memoria dinámica estática. También podría desembocar en la terminación del programa, representando una vulnerabilidad de divulgación de información o de denegación de servicio en aplicaciones que llaman a esas funciones APR con entradas externas no validadas. An out-of-bounds array dereference was found in apr_time_exp_get(). An attacker could abuse an unvalidated usage of this function to cause a denial of service or potentially lead to data leak. • http://www.apache.org/dist/apr/Announcement1.x.html http://www.openwall.com/lists/oss-security/2021/08/23/1 http://www.securityfocus.com/bid/101560 http://www.securitytracker.com/id/1042004 https://access.redhat.com/errata/RHSA-2017:3270 https://access.redhat.com/errata/RHSA-2017:3475 https://access.redhat.com/errata/RHSA-2017:3476 https://access.redhat.com/errata/RHSA-2017:3477 https://access.redhat.com/errata/RHSA-2018:0316 https://access.redhat.com/errata/RHSA • CWE-125: Out-of-bounds Read •
