ALPACA is an application layer protocol content confusion attack, exploiting TLS servers implementing different protocols but using compatible certificates, such as multi-domain or wildcard certificates. A MiTM attacker having access to victim's traffic at the TCP/IP layer can redirect traffic from one subdomain to another, resulting in a valid TLS session. This breaks the authentication of TLS and cross-protocol attacks may be possible where the behavior of one protocol service may compromise the other at the application layer. ALPACA es un ataque de confusión de contenido de protocolo de capa de aplicación, que explota servidores TLS que implementan diferentes protocolos pero que usan certificados compatibles, como certificados multidominio o comodín. Un atacante de tipo MiTM que tenga acceso al tráfico de la víctima en la capa TCP/IP puede redirigir el tráfico de un subdominio a otro, resultando en a una sesión TLS válida. • https://alpaca-attack.com https://bugzilla.redhat.com/show_bug.cgi?id=1975623 https://lists.debian.org/debian-lts-announce/2022/11/msg00031.html • CWE-295: Improper Certificate Validation •

NGINX before 1.13.6 has a buffer overflow for years that exceed four digits, as demonstrated by a file with a modification date in 1969 that causes an integer overflow (or a false modification date far in the future), when encountered by the autoindex module. NGINX versiones anteriores a 1.13.6, presenta un desbordamiento de búfer para los años que superan los cuatro dígitos, como es demostrado por un archivo con una fecha de modificación en 1969 que causa un desbordamiento de enteros (o una falsa fecha de modificación en el futuro), cuando es encontrado por el módulo autoindex • http://nginx.org/en/CHANGES https://github.com/nginx/nginx/commit/0206ebe76f748bb39d9de4dd4b3fce777fdfdccf https://github.com/nginx/nginx/commit/b900cc28fcbb4cf5a32ab62f80b59292e1c85b4b https://lists.debian.org/debian-lts-announce/2021/06/msg00009.html https://security.netapp.com/advisory/ntap-20210805-0006 https://trac.nginx.org/nginx/ticket/1368 • CWE-190: Integer Overflow or Wraparound •

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') •

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 •
