漏洞說明:
src_article.ASP中的
......
input["log_id"]=func.checkInt(input["log_id"]);
if(!input["id"]){
strError=lang["invalid_parameter"];
}else{
// Check if the article exists
theArticle.load("log_id, log_authorID, log_catID","log_id="+input["id"]);
strError=false;
}
......
過濾的是log_id,但是使用的確實(shí)id,呵呵 :)
然后呢?
class/article.ASP中的代碼
this.load = function(strselect, strwhere){
var tmpA=connBlog.query("select TOP 1 "+strselect+" FROM [blog_Article] where "+strwhere);
if(tmpA){
this.fill(tmpA[0]);
return true;
}else{
return false;
}
}
上面不用說了吧,呵呵.不過觸發(fā)要條件的,看能滿足不哦!
function articledelete(){
if(theUser.rights["delete"]<1){
// Check User Right - without DB Query
pageHeader(lang["error"]);
redirectMessage(lang["error"], lang["no_rights"], lang["goback"], "Javascript:window.history.back();", false, "errorbox");
}else{
var theArticle=new lbsArticle();
var strError;
默認(rèn)情況下guest都有刪除權(quán)限的,盡管后面還做了判斷,但是注入已經(jīng)發(fā)生,而我們正好利用他的判斷注射,呵呵
