Full Disclosure: RE: [OBORONA-SPAM] Critical bug in Web Wiz Forum

["Alexander" <pk95 () yandex ru>]

Small mistake:
SqL Injection In laryCheckedIPAddrID parameter in pop_up_ip_blocking.asp,
line  113:
For each laryCheckedIPAddrID in Request.Form("chkDelete")
...
        strSQL = "SELECT * FROM " & strDbTable & "BanList WHERE " &
strDbTable & "BanList.Ban_ID="  & laryCheckedIPAddrID & ";"  <-- Injection
here


Must be

laryCheckedIPAddrID = Cint(laryCheckedIPAddrID)
...
strSQL = "SELECT * FROM " & strDbTable & "BanList WHERE " & strDbTable &
"BanList.Ban_ID="  & laryCheckedIPAddrID & ";"
