108822 - [security] Any user can change their groupset!

Status: RESOLVED FIXED

(Bugzilla :: User Accounts, defect, P1)

Description

[Bradley Baetz (:bbaetz)]

userprefs.cgi has:

    SendSQL("UPDATE profiles SET mybugslink = '" . $::FORM{'mybugslink'} .
            "' WHERE userid = $userid");

playing with the mybugslink value on the form lets you do:

value="1', groupset='9223372036854775807"

It needs to be sqlescaped.

Yuck, that's nasty.  Once we get everything running in taint mode, it that'll be
a lot harder to do (because we'd have to validate it before we could pass it off
to the SQL server [running it through SqlQuote counts as validation]).

r=bbaetz. My exploit no longer works

Should we validate that its 0 or 1? The code only cares about 0 or !0.

Hmm, it seems the bulk change thinks I'm not changing anything if all I do is
add names to the CC list, so I guess I have to make a comment.  Anyhow, adding
the representatives from the organizations we know of that support Bugzilla
distributions so they're aware of our upcoming security release

Opening security bugs for which fixes have appeared in official bugzilla
