[Bug 1390988] Re: Username spoofing in chat
I cannot reproduce this in any NMDC hubs I tried (e.g. PtokaX DC Hub
0.5.2.1) with two users using the latest DC++ version, one with the nick
"nick" and the other set to "nick>"; then I tested with one of the
client's nick set to "hubbot_name>". In both cases the nicks displayed
with the ">" symbol at the end changed to "_" and can be perfectly
distinguished in both clients.
The behavior described in this report should have already been fixed
with https://bazaar.launchpad.net/~dcplusplus-
team/dcplusplus/trunk/revision/611/client/NmdcHub.cpp#client/NmdcHub.cpp
and the fix is released with DC++ 0.692 so I'm not sure how this can
happen in 0.843 or any newer version.

Title:
Username spoofing in chat
Status in DC++:
New
Bug description:
">" symbol at the end of a username gets stripped off while being
displayed in public/private chat. So this will allow impersonation of
users on chat. Check the attached screenshot. By connecting to the hub
with the username "PtokaX>" (NMDC), all my public/private chat
messages will appear to dcplusplus users as if they are from "PtokaX"
itself.
Version: 0.843
Hub software used for testing: PtokaX 0.5.0.2
OS: Windows XP SP3
