Open Resty Improper Neutralization of Special Elements used in an SQL Command (SQL Injection) Vulnerability - CVE-2018-9230

DISPUTED 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 vendor39s 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.
