Google Project Zero recently announced a 20 year old local privilege exploit (LPE) affecting all versions of Windows both server and client versions from Windows Server 2003 through Windows Server 2019 and Windows XP all the way through Windows 10. It takes advantage of the “ctfmon.exe” process which is a shared service for processing text input. This process doesn’t have access controls which means a malicious request to it will allow an unprivileged user to gain SYSTEM privileges. Microsoft has release a patch in their August updates.
Earlier this week the same researchers that found the original set of vulnerabilities in the Dragonfly handshake for WPA3 have found two more. I thought WPA3 would be less vulnerable than WPA2 but it seems the WiFi Alliance continues to struggle with coming up with a secure algorithm to prevent unauthorized access. The WiFi Alliance recently announced WPA3.1 which will not be vulnerable to these attacks but that’s also at the expense of backward comparability. If you are in the market now for a WPA3 enabled router I would suggest waiting a little bit longer for WPA3.1 to come out.

This was just in a SANS AtRisk email that I’m subscribed to. If you are using this VPN appliance please be aware of this format string vulnerability. It’s both pre-auth and also capable of remote code execution (RCE). Palo Alto was already aware of this vulnerability internally and they patched the vulnerability, begining with PAN-OS v9.0, which is now shipping with this appliance. However the appliance bought before the patch was made are most likely still running a vulnerable version of PAN-OS so please update to the latest version of PAN-OS:
Will the United State government ever learn that by making the encryption keys available to law enforcement it’s setting up the potential for the keys to be stolen by an adversary? This is just plain dumb.
The folks that run the website RTL-SDR have a comprehensive list of all the software defined radio (SDR) software, both commercial and free. That list can be found here:
I ran across this awesome article discussing different ways you can disable and/or bypass the execution policy in PowerShell. Turns out they found 15 of them! This is critical when you are performing penetration tests and using techniques such as “living off the land”.
Well it turns out the folks wearing tin foil hats were right about this! Now if only Facebook would admit it’s tapping my cell phone mic to generate advertisements on my Wall… 😉
While I was trolling around on Twitter this morning PortSwigger tweeted about their latest release of Burp Suite which now supports intercepting WebSockets. Check out their release note regarding v2.1.01. This feature also appears to be in the Community version as well as their Professional version:
