Cisco Network Assurance Engine CLI default user/password. At this point, I'm assuming anything Cisco has an unpublished admin user/password somewhere!

This one seems like an actual bug, and not a hard coded password.
From what I read, the TL;DR version is that when you change your web interface password, it doesn't change your CLI password.
I didn't get a chance to do more than glance at this one. That's actually worse. How do you screw up a credential system that bad?
This is actually a very common design. Nearly all systems are this way. One password is to the system, one is to the application on the system. Totally normal.
You're assuming it was supposed to be designed that way.

No, I'm stating that it is super normal and expected. It's only that you assume that it is supposed to be designed differently that makes it seem weird. It's good to tie the two together in many cases, but very few vendors do, it should never be assumed.

Then shouldn't you also have different account names as well? Not having a different account name, or documentation clearly spelling the difference out, creates a human based security hole. (Not that people actually read documentation.)
Also, just because it's common, doesn't mean it's right. (Just getting it out there.)

Only 17 more on the list this morning. Most of them are probably not horrible, but there are some remote vulnerabilities in there. No, I haven't reviewed any of them myself yet.

RV110W, RV130W, and RV215W routers management interface remote vulnerability.

Go patch all your Cisco things. Lots of stuff they classify as High priority and a fix for the router vulnerability from last week.
-
Only 2 things today. They must have had a slow week.

According to CISA, one is yet another hardcoded credential, and one is a DDOS vulnerability.

Another remote vulnerability. Just another week in the Cisco world.

@NashBrydges said in Cisco Security Vulnerability Thread.:
wow
Red Balloon Security researchers have demonstrated physical destruction of Cisco routers by leveraging Thrangrycat via remote exploitation
ouch!

@NashBrydges said in Cisco Security Vulnerability Thread.:
Thanks for posting. Saw this headline, but didn't get to actually read the article yet.
-
Looks like that vulnerability is worse than expected.
-
Multiple vulnerabilities patched this month. Make sure you're account is paid up so you can keep everything updated. Or more reasonably toss the gear for something reasonably priced.
At least 1 remote vulnerability, again.

LOL
