To keep this blog shorter I am going to assume you have a working knowledge of Windows network authentication, and specifically Kerberos and NTLM. For a quick primer on Kerberos see this page which is part of Microsoft's Kerberos extension documentation or you can always read RFC4120. --------------------------------------------- https://googleprojectzero.blogspot.com/2021/10/using-kerberos-for-authentic… ∗∗∗ Windows Exploitation Tricks: Relaying DCOM Authentication ∗∗∗ --------------------------------------------- In my previous blog post I discussed the possibility of relaying Kerberos authentication from a DCOM connection. I was originally going to provide a more in-depth explanation of how that works, but as it's quite involved I thought it was worthy of its own blog post. This is primarily a technique to get relay authentication from another user on the same machine and forward that to a network service such as LDAP. You could use this to escalate privileges on a host using a technique similar to a blog post from Shenanigans Labs but removing the requirement for the WebDAV service. Let's get straight to it. --------------------------------------------- https://googleprojectzero.blogspot.com/2021/10/windows-exploitation-tricks-… ∗∗∗ GPS Daemon (GPSD) Rollover Bug ∗∗∗ --------------------------------------------- Critical Infrastructure (CI) owners and operators and other users who obtain Coordinated Universal Time (UTC) from Global Positioning System (GPS) devices should be aware of a GPS Daemon (GPSD) bug in GPSD versions 3.20 (released December 31, 2019) through 3.22 (released January 8, 2021). On October 24, 2021, Network Time Protocol (NTP) servers using bugged GPSD versions 3.20-3.22 may rollback the date 1,024 weeks—to March 2002—which may cause systems and services to become unavailable or unresponsive. CISA urges affected CI owners and operators to ensure systems—that use GPSD to obtain timing information from GPS devices—are using GPSD version 3.23 (released August 8, 2021) or newer. --------------------------------------------- https://us-cert.cisa.gov/ncas/current-activity/2021/10/21/gps-daemon-gpsd-r… ∗∗∗ CVE-2021-28632 & CVE-2021-39840: Bypassing Locks in Adobe Reader ∗∗∗ --------------------------------------------- Over the past few months, Adobe has patched several remote code execution bugs in Adobe Acrobat and Reader that were reported by researcher Mark Vincent Yason (@MarkYason) through our program.
