Descriptions

In OpenResty through 1.13.6.1, URI parameters are obtained using the ngx.req.get_uri_args and ngx.req.get_post_args functions that ignore parameters beyond the hundredth one, which might allow remote attackers to bypass intended access restrictions or interfere with certain Web Application Firewall (ngx_lua_waf or X-WAF) products. NOTE: the vendor has reported that 100 parameters is an intentional default setting, but is adjustable within the API. The vendor's position is that a security-relevant misuse of the API by a WAF product is a vulnerability in the WAF product, not a vulnerability in OpenResty

** EN DISPUTA** En OpenResty hasta la versión 1.13.6.1, los parámetros URI se obtienen utilizando las funciones ngx.req.get_uri_args y ngx.req.get_post_args que ignoran los parámetros posteriores al centésimo, lo que permite que los atacantes omitan las restricciones de acceso o interfieran con determinados productos Web Application Firewall (ngx_lua_waf o X-WAF). NOTA: el fabricante ha notificado que 100 parámetros es una configuración por defecto intencional, pero puede ajustarse en la API. La postura del fabricante es que un uso erróneo relevante para las seguridad de la API por parte de un producto WAF es una vulnerabilidad del producto WAF, no en OpenResty.
