CVE-2019-20372 – nginx: HTTP request smuggling in configurations with URL redirect used as error_page
https://notcve.org/view.php?id=CVE-2019-20372
NGINX before 1.17.7, with certain error_page configurations, allows HTTP request smuggling, as demonstrated by the ability of an attacker to read unauthorized web pages in environments where NGINX is being fronted by a load balancer. NGINX versiones anteriores a 1.17.7, con ciertas configuraciones de error_page, permite el trafico no autorizado de peticiones HTTP, como es demostrado por la capacidad de un atacante para leer páginas web no autorizadas en entornos donde NGINX está al frente de un equilibrador de carga. • https://github.com/0xleft/CVE-2019-20372 https://github.com/vuongnv3389-sec/CVE-2019-20372 http://lists.opensuse.org/opensuse-security-announce/2020-02/msg00013.html http://nginx.org/en/CHANGES http://seclists.org/fulldisclosure/2021/Sep/36 https://bertjwregeer.keybase.pub/2019-12-10%20-%20error_page%20request%20smuggling.pdf https://duo.com/docs/dng-notes#version-1.5.4-january-2020 https://github.com/kubernetes/ingress-nginx/pull/4859 https://github.com/nginx/nginx/commit • CWE-444: Inconsistent Interpretation of HTTP Requests ('HTTP Request/Response Smuggling') •

CVE-2017-7529 – nginx: Integer overflow in nginx range filter module leading to memory disclosure
https://notcve.org/view.php?id=CVE-2017-7529
Nginx versions since 0.5.6 up to and including 1.13.2 are vulnerable to integer overflow vulnerability in nginx range filter module resulting into leak of potentially sensitive information triggered by specially crafted request. Las versiones desde la 0.5.6 hasta 1.13.2 incluyéndola de Nginx, son susceptibles a una vulnerabilidad de desbordamiento de enteros en el módulo filtro de rango de nginx, resultando en un filtrado de información potencialmente confidencial activada por una petición especialmente creada. A flaw within the processing of ranged HTTP requests has been discovered in the range filter module of nginx. A remote attacker could possibly exploit this flaw to disclose parts of the cache file header, or, if used in combination with third party modules, disclose potentially sensitive memory by sending specially crafted HTTP requests. • https://github.com/liusec/CVE-2017-7529 https://github.com/MaxSecurity/CVE-2017-7529-POC https://github.com/Shehzadcyber/CVE-2017-7529 https://github.com/SirEagIe/CVE-2017-7529 https://github.com/cyberk1w1/CVE-2017-7529 https://github.com/cyberharsh/nginx-CVE-2017-7529 https://github.com/coolman6942o/-Exploit-CVE-2017-7529 https://github.com/fu2x2000/CVE-2017-7529-Nginx---Remote-Integer-Overflow-Exploit http://mailman.nginx.org/pipermail/nginx-announce/2017/000200.html http: • CWE-190: Integer Overflow or Wraparound •

CVE-2016-0747 – nginx: Insufficient limits of CNAME resolution in resolver
https://notcve.org/view.php?id=CVE-2016-0747
The resolver in nginx before 1.8.1 and 1.9.x before 1.9.10 does not properly limit CNAME resolution, which allows remote attackers to cause a denial of service (worker process resource consumption) via vectors related to arbitrary name resolution. El traductor de direcciones en nginx en versiones anteriores a 1.8.1 y 1.9.x en versiones anteriores a 1.9.10 no limita correctamente la resolución CNAME, lo que permite a atacantes remotos provocar una denegación de servicio (consumo de recursos por el proceso trabajador) a través de vectores relacionados con la resolución de nombre arbitrario. It was discovered that nginx did not limit recursion when resolving CNAME DNS records. An attacker able to manipulate DNS responses received by nginx could use this flaw to cause a worker process to use an excessive amount of resources if nginx enabled the resolver in its configuration. • http://lists.opensuse.org/opensuse-updates/2016-02/msg00042.html http://mailman.nginx.org/pipermail/nginx/2016-January/049700.html http://seclists.org/fulldisclosure/2021/Sep/36 http://www.debian.org/security/2016/dsa-3473 http://www.securitytracker.com/id/1034869 http://www.ubuntu.com/usn/USN-2892-1 https://access.redhat.com/errata/RHSA-2016:1425 https://bto.bluecoat.com/security-advisory/sa115 https://bugzilla.redhat.com/show_bug.cgi?id=1302589 https://security.gentoo • CWE-400: Uncontrolled Resource Consumption •
