Error 1054 (42S22) when create a new rule into the WAF

[wen0750]

I want to add a new rule into the waf. But I got an error:

"Error 1054 (42S22): Unknown column 'uid' in 'field list'"

But I don't see any uid in the payload, so I don't know what's going on.

My UUWAF version is : v6.7.0

Here is the rule that I want to create.

local ct = waf.reqContentType
local rurl = waf.reqUri
local fd = waf.form["FORM"]

if rurl and fd then
    if waf.reqUri == "blog/admin_action.php" and fd["submit"] == "xxxxxxxxx" then
        return false
    end
end 

if ct then
    if type(ct) ~= "string" then
        return true, "Malform Content-Type", true
    elseif waf.contains(ct, "boundary") and (waf.strCounter(ct, "boundary") > 1 or not waf.rgxMatch(ct, "boundary=[\\w\\-]+$", "jo")) then
        return true, ct, true
    end
end

return false

This is the payload submitted from the frontend to the backend.

{
  "id": 0,
  "name": "xxxxxxxxx - boundary异常拦截",
  "type": "0",
  "level": "3",
  "description": "1.拦截请求content type头中multipart/form-data的异常boundary，如php在上传解析boundary时没有符合rfc规范，对逗号产生了错误解析。2. This rule will be skip the checking on the admin page api of the xxxxxxxxx.",
  "content": "local ct = waf.reqContentType\nlocal rurl = waf.reqUri\nlocal fd = waf.form[\"FORM\"]\n\nif rurl and fd then\n    if waf.reqUri == \"blog/admin_action.php\" and fd[\"submit\"] == \"xxxxxxxxx\" then\n        return false\n    end\nend \n\nif ct then\n    if type(ct) ~= \"string\" then\n        return true, \"Malform Content-Type\", true\n    elseif waf.contains(ct, \"boundary\") and (waf.strCounter(ct, \"boundary\") > 1 or not waf.rgxMatch(ct, \"boundary=[\\\\w\\\\-]+$\", \"jo\")) then\n        return true, ct, true\n    end\nend\n\nreturn false",

  "dsl": [ {"key": "", "op": "", "val": ""} ]
}

Also, there is a .har file but Github is not allow to upload this extension. So I changed the extension type of the file. If you need you can download it and change it back. uuwaf.har.log

数据库表差uid字段引起的，不同waf版本的数据库表结构可能不同，不要通过备份恢复来同步数据库
