Help with Microsoft DCE RPC Big Endian Evasion Vulnerability 33510

smc007 — Thu, 13 Sep 2018 15:42:01 GMT

I have Googled this and read up on numerous links, but I cannot find anything of value on this threatID. I have 30-40 events a day from various IP addresses on my network, usually 1 event per IP, sometimes 2 events. I have scanned several of the PC's with 3 different popular scanners, nothing found. I have monitored the traffic from the PCs and nothing is talking to suspicious IP addresses. I cannot find a specific Microsoft patch associated with this vulnerability.

Any thoughts on this? false positive? Is there a MS patch to ensure my systems aren't vulnerable?

Thank you.

Hello,

While it could be a false positive, it might not be ( tough to say). I would suggest gathering a pcap and see what is actually going on. PAN support can assist if you need them to. Also make sure the following is installed:

Also in my experience, I block anything meduium or higher.

Hope that helps.
