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." } ] }, "problemtype" : { "problemtype_data" : [ { "description" : [ { "lang" : "eng", "value" : "n/a" } ] } ] }, "references" : { "reference_data" : [ { "name" : "https://github.com/Bypass007/vuln/blob/master/OpenResty/Uri%20parameter%20overflow%20in%20Openresty.md", "refsource" : "MISC", "url" : "https://github.com/Bypass007/vuln/blob/master/OpenResty/Uri%20parameter%20overflow%20in%20Openresty.md" }, { "name" : "https://openresty.org/en/changelog-1013006.html", "refsource" : "MISC", "url" : "https://openresty.org/en/changelog-1013006.html" } ] } }
