One thing is for sure -

We can't even begin to evaluate the security exposures that may have been addressed in a given build without the support of the ethical hacking community, as our service providers and their vendors refuse to disclose which security fixes have been addressed in a given build. Yet, they persist in their execution of home invasions as they thrust upon us their new builds, without our informed consent.

And sadly, our service provider's gateways/routers can pwn/compromise our internal networks (including our customer-owned personal routers [yes, them too, Louise, even if said device is in bridge mode]) And there is no accountability... yet. :)

p.s.

According to Arris, if you try to co-manage your cable device, you are a loser-

$ curl  "http://192.168.100.1:8080/walk?oid=1.3.6.1.4.1.4115" -v> GET /walk?oid=1.3.6.1.4.1.4115 HTTP/1.1> Host: 192.168.100.1:8080> User-Agent: curl/7.43.0> Accept: */*< HTTP/1.1 401 Unauthorized< Status: 401 Denied! - loser< Transfer-Encoding: chunked< Date: Mon, 11 Apr 2016 04:24:43 GMT< Server: lighttpd 

So if you are computer literate, perhaps a coder, you are a loser, at least little Johnny thinks so. Thanks for the encouragement, my TWC fiends.

Little Johnny: That is so immature to call your parents, and grandparents losers. Remember who changed your diapers! Losers Johnny? Is that what you think? Keep coding little Johnny, but when you get to high school, you will find out who the real losers are. :)

p.s. My BarMizvah gift to Little Johnny, should at least pay for his therapy, and possibly graduate school.

nony posted : kba4,

Here's a more recent blurb -

TurboDOX is a TI-proprietary protocol, supported in hardware. Enabling TurboDOX increases performance of TCP-based protocols such as FTP and HTTP. TurboDOX is enabled by default. You may need to disable TurboDOX during customer traffic testing and lab evaluations. ARRIS recommends that TurboDOX remained enabled in field deployments.

(This was way back in 2009, and may only conditionally apply in certain environments, [Docsis 2.0 fallback?] if at all)
---

This parameter continues to be supported in the Arris Docsis 3.0 MIB (ARRIS-CM-DOC30-DEVICE-MIB)
LAST-UPDATED "1507160000Z" -- Jul 16, 2015 -
»www.bowe.id.au/michael/i ··· oc30.mib

And from mibs.js (192.168.100.1:8080/mibs.js), we have -
// ARRIS ADD START for PROD00203656
var CmDoc30Setup = new Container("CmDoc30Setup","1.3.6.1.4.1.4115.1.3.4.1.3");
CmDoc30Setup.TurboDoxEnable = new Scalar("CmDoc30SetupTurboDoxEnable","1.3.6.1.4.1.4115.1.3.4.1.3.14",2);
CmDoc30Setup.CmDoc30SetupSecDsLossReinitEnable = new Scalar("CmDoc30SetupSecDsLossReinitEnable","1.3.6.1.4.1.4115.1.3.4.1.3.4",2);
CmDoc30Setup.CmDoc30SetupPartServiceFallback20 = new Scalar("CmDoc30SetupPartServiceFallback20","1.3.6.1.4.1.4115.1.3.4.1.3.5",2);
CmDoc30Setup.CmDoc30SetupPacketCableRegion = new Scalar("CmDoc30SetupPacketCableRegion","1.3.6.1.4.1.4115.1.3.4.1.3.8",2);
var arCmDoc30SetupTurboDoxEnable = CmDoc30Setup.TurboDoxEnable;
var arCmDoc30SetupSecDsLossReinitEnable = CmDoc30Setup.CmDoc30SetupSecDsLossReinitEnable;
var arCmDoc30SetupPartServiceFallback20 = CmDoc30Setup.CmDoc30SetupPartServiceFallback20;
var arCmDoc30SetupPacketCableRegion = CmDoc30Setup.CmDoc30SetupPacketCableRegion;
// ARRIS ADD END for PROD00203656


Why they exposed Turbodox in the UI remains a mystery to me. They hide everything else that doesn't pertain to your MSO's standard/customized configuration.

Sloppy work.

p.s. - Useful MIB walks that continue to work:

Default user credentials should work [admin:password] (or whatever you may have changed it to), by design.

I'm sure that Dr. Drew (my favorite TWC surrogate by far), agrees with everything I have posted (more or less) :)

OHnetguy posted : I'm in NE Ohio. I've had flawless TWC service since December 2015 (50/5 ultimate).

On April 9th, HSD logs show that new firmware was uploaded to my TG1672G and it was subsequently rebooted. I was online at the time.

I have one PC connected to LAN and various devices (including my laptop I use 99% of the time) connected over wireless. Immediately after the new firmware was uploaded and the device was rebooted, I started experiencing wireless disconnections.

HSD logs show less than 24 errors in the past seven days. Signal is good. HSD/Internet side of things is fine. My LAN PC has not gotten disconnected. But my laptop ends up disconnecting / being disconnected from the router multiple times a day, often during times when I'm doing something important and often (but not always) during times when I'm using some bandwidth (watching a video). At the same time that my laptop wireless becomes disconnected, my ROKU wireless loses connection as well.

I called TWC and they had me reset to factory defaults (hold down button on back of unit for 30 seconds) and then the tech remotely reconfigured my wireless settings. That did not help.

I have attempted to disable IPV6 on all devices that i could. The only thing using IPV6 right now is my iPhone. I forced everything to use 2.4 Ghz because it seems/seemed that I was getting disconnected less when nothing was using 5.4 Ghz. But, even with everything on 2.4 Ghz and my iPhone turned off (thus no IPV6 activity), this still happens.

This is a three year old Dell Inspiron 17R. I've experienced disconnections from wireless when connected to various access points over the years, and basically I would not know that I was disconnected from wireless until I tried to browse a website. But, with these wireless disconnections that I'm seeing now, I notice that when the laptop loses connection and tries to re-establish connection I can barely move the mouse around or do anything on the laptop (the whole thing becomes somewhat unresponsive) until the wireless connection is re-established.

Wireless re-connection is usually established within a minute. And I can go for hours and hours without a disconnection as long as not much traffic is beig generated. As soon as one tries to watch a video (on the laptop or roku or phone) or upload/download something of significance, that's usually when I lose connection.

As mentioned before -- HSD logs will not be useful here because there are no errors - signal levels are good and the internet connection itself never goes down. The router logs themselves do not reveal anything useful -- show no sign that anything is disconnecting/reconnecting to teh wireless, even though I know that just about everything on wireless is getting disconnected and having to reconnect at the same times.

Does anyone here have any recommendations?

Thanks

My colony's Arris TG1672 got updated!

Mike Wolf posted : An example that comes to mind is a firmware update that either disables the fan temp sensor or sets it to an extremely high value and the hardware cooks itself to death because the cooling fan either never kicks in or can't catch up.

Oh it can. At the very least it can "brick" the firmware chip. A great deal of modern hardware can recover from that with some form of factory reset, but it's often a pain in the royal behind, and not always successful.

The most common hardware failures from firmware updates are related to overheating. Some bugged code could generate a faulty "runaway" process on the processor of the device, causing said processor to overheat, in turn causing physical damage to a device that cannot be reverted.

A good example here is overclocking. Many custom firmwares allow overclocking of devices, making the processor run much hotter than it was designed for. Now if you have GOOD cooling, that should not always mean a problem, but I have seen overclocked CPU's literary MELT into a mainboard because some punk had read online which BIOS settings to change to get a higher CPU clock, failing to take overheating/cooling into account.

The old DD-WRT firmware for Linksys routers allowed overclocking of its internal CPU. If you clock it too high, and it's a hot summer day.... You can fry up your router. And those are software changes.

Now imagine a bug that would accidentally enable overclocking to a much higher level than recommended. Wanna bet software can fry your hardware?

This modem will still get its own IP/IPv6 address even in bridge mode. This firmware still has not corrected this issue. It looks like like this problem is present in all Arris DGxxx/DGxxxx modem/gateways.

If you want to see what unadulterated Arris release notes can look like, I will try to dig something up (iff it's publicly accessible) -

from a release 7 bundle ---> »documents.tips/documents ··· -10.html (We are on release 9)

Also worth mentioning - your favorite intel agency will get a superset of the above, for obvious reasons.
