Digium Asterisk WebSocket Frame Empty Payload Denial-of-Service Vulnerabi

KRisselada — Mon, 06 Jul 2020 20:22:22 GMT

How do I report or provide feedback regarding the Cortex Alert named "Digium Asterisk WebSocket Frame Empty Payload Denial-of-Service Vulnerability" that are being generated by the PAN NGFW, with the Initiator CMD of:

"C:\Program Files\WindowsApps\Microsoft.Office.OneNote_16001.12827.20182.0_x64__8wekyb3d8bbwe\onenoteim.exe" -ServerName:microsoft.onenoteim.AppXxqb9ypsz6cs1w07e1pmjy4ww4dy9tpqr.mca"

We have had this alert generate 9 times since 7 May 2020. Always with the same category of "Vulnerability", same Description "Vulnerability Exploit Detection" and most every time the same CGO of sihost.exe (or possibly another MS Office app such as Excel)

I believe it to be a false positive
