Summary0002023: SVSMODE removal of oper modes has unpredictable effect
DescriptionWhen a U:Lined server attempts to remove an opers modes (e.g. +o, +N, +A), the SVSMODE succeeds in removing the opers modes from their struct but certain permissions (e.g. the ability to /rehash) are still kept for that user, so a user that has been 'de-opered' can still do certain oper-only commands.
Steps To ReproduceThrough a u:lined server such as services or defender, send an SVSMODE OperNick -oghaANW.
As OperNick, /rehash the local server.
Additional InformationDiscovered via ircdefender version 1.3.10 secureoper module.
TagsNo tags attached.

Well this is really a problem with ircdefender not supporting Unreal correctly. It should send the SVSO command after sending the SVSMODE to remove modes. The SVSO removes the oper flags.

Hehe, the wonders of telnet actually suggest that SVSO Target - is enough (Unreal will unset the oper modes itself _and return this change_) :D .

But it doesnt remove some of them as we discovered... what were they? infected dcc notices.... bugger. Jason'd know.

+v (dcc notices) and +g (globops)

Those were the ones.

Umm, you seem correct about umode +v, however, +g is a user settable mode. Was +g a typo, or...?

No it wasn't a typo... but...

>+g is a user settable mode.

It is? I don't recall it doing anything for users :/ ... or does it?

Yeah, there are a few +g messages sent to non-opers. Why exactly, I don't know, but they do exist.

Anyway, SVSO now removes +v as of .129
