CVE-2021-23017 5 F5, Fedoraproject, Netapp and 2 more 13 Nginx, Fedora, Ontap Select Deploy Administration Utility and 10 more 2022-07-12 6.8 MEDIUM 9.4 CRITICAL

CVE-2018-9230 1 Openresty 1 Openresty 2018-05-15 7.5 HIGH 9.8 CRITICAL
** 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 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.
