Two vulnerabilities were discovered in Nginx, a high-performance web and reverse proxy server, more precisely in ngx_http_lua_module, which embeds the Lua scripting language into Nginx. This could lead to request smuggling or contribute to cache poisoning and authentication bypass.
ngx_http_lua_module is provided by the optional libnginx-mod-http-lua binary package.
CVE-2020-36309
ngx_http_lua_module allows unsafe characters in an argument when
using the API to mutate a URI, or a request or response header.
CVE-2024-33452
lua-nginx-module allows a remote attacker to conduct HTTP request
smuggling via a crafted HEAD request.
