Hit By Misfortune Cookie | Router Breached - BreShiE - 03-05-2015
Yep! As a brilliant bombshell to finish the day on, I believe I've been hit by the oh-so-known Misfortune Cookie. I never really thought anything of this vuln other than "someone's gonna get a lot of dildo power". Anyway, let's get on with it!
I was trolling @Blunt, as he was I, earlier so I logged into my router to check up on my settings and to check the system logs and firewall settings etc and started noticing some suspicious looking logs. The first ones being:
Quote:01:54:26 05/03/2015 | Security | Warning | Detect UDP port scan attack, scan packet from IP.
This got me interested, as I knew for sure I hadn't ran a port scan on myself. So I delved a little further and found the following logs by switching to "sort by type > Type Security":
Quote:08:34:08 04/03/2015 Security Warning Intrusion -> SRC=78.189.153.180 DST= LEN=60 TOS=0x00 PREC=0x00 TTL=53 ID=29663 DFPROTO=TCP SPT=45520 DPT=23 WINDOW=5808 RES=0x00 SYNURGP=0

I instantly assumed Misfortune Cookie from this. Then @Yagmi started informing me about an open gateway on my connection and eventually pinned it down to a remote access service (TR-069) and I then disabled it. However there are multiple logs suggesting that I have in fact been breached by Misfortune Cookie. What's confusing me though, is on the official information website for Misfortune, there's this segment:
Quote:Can I detect if I was compromised using Misfortune Cookie?
Typically you would not have logs or other traces of Misfortune Cookie exploitation. General warning signs may be the inability to log in to the web interface or the discovery of changed settings in your device.
There are many logs. Some notifying me of changes to my router via TR-069 and some of actual access logs.
We'll see where this goes. If any more suspicious activities ensues, I'll just revert back to my old device. I'm removing all inactive and unknown devices just to be on the safe side. You never know!
Here are some more fun logs for you guys:

Incase anyone doesn't know what the "Misfortune Cookie" is, it's a vulnerability floating around in some 12 million home routers. It's caused by an error in the way the HTTP interface handles cookies, someone can send a specially crafted cookie and trick the application into treating the attacker's session with administrative privileges.

Which makes the vulnerability extremely fucking bad. Still not sure if it was a targeted attack against me or just from a random net-wide scan. Well, the panel is no longer up and there is no external connection from my modem to the internet. Internal connections only!

This and many other bugs further make me question why the fuck people buy routers that can be accessed externally

I would suggest reverting to old device anyway.
I mean no reason to willingly run around with a huge vuln correct?

After months and months of problems following this thread, I finally got a new router and now everything's fine! It's gone from my connection dropping well over 20 times a day to once or twice every few days.

Thanks for the information, here at SL everyone cares about how BreShie's internet is doing!

Go somewhere else and try to start an argument. You're not worth my time.
