Duplicating Items

[Alexer]

L2J Revision 4319:
L2JDP Revision 7549:

Can anyone explain to me how he did it? I didn't managed to find out. He was trading and he doubled his items by trades. Not only gold bars.
Checking the login logs, i observed that when he was making this trades, the player logged in and out a lot. It must be an issue but i dont figure it out. At this moment my server is closed.
Maybe someone will tell me how he did it and what is the solution? Updating L2J Revision will work?

Code: Select all

[18 Sep 1:53:15] CHANGE:Trade, item 268748513:Gold Bar(1), L2PcInstance:Garones[268706280], L2PcInstance:Insensitive[268705950][18 Sep 1:53:15] CREATE:Trade, item 268749003:Gold Bar(5), L2PcInstance:Garones[268706280], L2PcInstance:Insensitive[268705950] [18 Sep 1:53:48] DELETE:Trade, item 268749003:Gold Bar(0), L2PcInstance:Insensitive[268705950], L2PcInstance:Garones[268706280][18 Sep 1:53:48] CHANGE:Trade, item 268748513:Gold Bar(11), L2PcInstance:Insensitive[268705950], L2PcInstance:Garones[268706280]  [18 Sep 1:56:03] CHANGE:Trade, item 268748513:Gold Bar(1), L2PcInstance:Garones[268706280], L2PcInstance:Insensitive[268705950][18 Sep 1:56:03] CREATE:Trade, item 268749265:Gold Bar(10), L2PcInstance:Garones[268706280], L2PcInstance:Insensitive[268705950] [18 Sep 1:56:35] DELETE:Trade, item 268749265:Gold Bar(0), L2PcInstance:Insensitive[268705950], L2PcInstance:Garones[268706280][18 Sep 1:56:35] CHANGE:Trade, item 268748513:Gold Bar(21), L2PcInstance:Insensitive[268705950], L2PcInstance:Garones[268706280] [18 Sep 1:58:29] CHANGE:Trade, item 268748513:Gold Bar(1), L2PcInstance:Garones[268706280], L2PcInstance:Insensitive[268705950][18 Sep 1:58:29] CREATE:Trade, item 268749420:Gold Bar(20), L2PcInstance:Garones[268706280], L2PcInstance:Insensitive[268705950] [18 Sep 1:58:59] DELETE:Trade, item 268749420:Gold Bar(0), L2PcInstance:Insensitive[268705950], L2PcInstance:Garones[268706280][18 Sep 1:58:59] CHANGE:Trade, item 268748513:Gold Bar(41), L2PcInstance:Insensitive[268705950], L2PcInstance:Garones[268706280]

Can anyone explain to me how he did it?

L2J Revision 4319

[kocinski]

I think that exploit was fixed here: http://trac.l2jserver.com/changeset/4408

[Alexer]

I'm interested about how it was done so I can be able to test after i update l2j version. Maybe someone send me a pm to not spread it.

[Alexer]

Sorry for double posting. I just don't know where to post this.
Since i didn't had time till now because of my job, i wanted to start the updates this night. But i can't see the changesets diffs on L2J Timeline. Is requesting me to login because i dont have FILE_VIEW privileges.
I want to manually update from rev 4319 to the newest one.
Can you tell me why i cant see the diffs? Last night I could.

[jurchiks]

Confirmed, I can't see them too.
Probably TPB is doing smth with trac settings or more. Should be over tomorrow.

[Alexer]

How much bad luck can i have?
1. Some guy is using an exploit to mess up my server.
2. When i finally have the time to fix it, by updating to a newer revision, l2jserver restricts the trac diffs. I can see the diffs in eclipse but is way out of hand since every time i see my custom scripts also as difs.

But at least can you answer me how it will be? It will remain like this (with FILE_VIEW restriction) or it will go back to normal? I hope I can call it normal how it used to be.

Congrats for the job you're doing it. L2JServer is the best.

LOL, old revisions contains tons of such things. Update, and stop useless crying.

[hiroshima]

[_DS_]

Shutdown server until you update it.

[Alexer]

Well,
I updated till the last epilogue revision. I have the same problem. I guess i'm forced to update to Freya. Hope that is fixed.
