Activity on Signature 31359

Ronald Nutter

Level 1

Seeing this signature firing quite a bit in the past hour.  Intially started seeing activity from ASIAPAC and Europe, Now seeing activity from the US.

Told our IPS to drop packets but not alert.

Anyone else seeing this signature fire ?

Yes, we're seeing the same.  Started with Signature version 528.0 for us at the noon auto update today.  It was frequently blocking http responses from our web server to web clients.  We had to disable the signature till we figure out what is going on.  The full name of the signature is: Microsoft Internet Explorer Invalid Flag Reference Remote Code Execution Vulnerability

Cisco has noted this activity as well:

http://tools.cisco.com/security/center/viewAlert.x?alertId=21736

"Microsoft has indicated that targeted attacks have been observed in the wild.  Current exploits may be prevented on Windows systems that implement Data Execution Prevention (DEP).  Windows Vista and 7, along with Windows Server 2003 and 2008, incorporate DEP, reducing risk on these systems."

The extra special bonus?  No patch is available at the moment ... fun.

"Microsoft has confirmed the vulnerability in a security advisory; however, software updates are not available."

This signature was just added in S528, which rolled out within the last 24 hours.  That might explain why you haven't seen it until now.

Me too, especially from https://www.google.com/ig

Anybody else?

Same here, also lot's of trafic coming from *.live.com

Same here.  We've been seeing alerts from various websites.

We're seeing this signature fire on accessing legitimate websites such as ap.org (Associated Press) and others.

Hello tscislaw,

If you are seeing the signature fire on suspected benign traffic, do you mind providing a capture of the trigger packets so that we can compare it to what the signature should match?

Thank you,

Blayne,

There's nothing in the trigger packet tab. Here's a copy of the "show all details" on the event for www.ap.org (Associated Press). Also had one this morning for www.netflix.com. It's also copied below.

We're continuing to get hits on all variety of sites, including internal ones.  We've scrubbed our stuff

and haven't found anything.  Can anyone confirm that the signature is perhaps being overzealous? I'd rather not mark it as safe and miss something that has a legitimate threat in the wild.

Hello,

We need to check on the captures what is triggering the signature, as of yet we need to see them with wireshark to analyze the payload. If possible can anyone providea packet capture of this nature, and also, would you please set some websites exmaples that are triggering the signature?

Thanks.

Mike

Mike

yimg.com is one site but we also have some internal Solarwinds sites that are getting spiked by this. I'll see if I can release a packet capture to you.

Is there somewhere private I can post the capture to?

I have a packet out of IME for both a Solarwinds session and what I think is a web based email session with American University's website.

Ok, here's one from Yahoo.  I'm not too worried about putting this one out there.  I captured this from IME in both the trigger packet and context data tabs:
