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.

Are the previews controlled by Explorer or is it done in another process? Are these handlers abusable?

Überwachungskameras, sollte viel mehr im Fokus von Herstellern und Nutzern liegen. In der Realität ist dies leider nicht der Fall. Jahr für Jahr werden mehr IoT-Geräte entdeckt, die eine P2P-Cloud-Verbindung nutzen. Der Defcon-Talk von Paul Marrapese letztes Jahr und die letzte Entdeckung von Mandiant beschreiben nur einen Auszug dessen, was sich in diesem Bereich der IT-Security abgespielt hat. Im Rahmen dieses Blogposts möchten wir Ihnen aktuelle Informationen zur zugrundeliegenden IoT-Sicherheitsproblematik anhand eines konkreten Gerätes vorstellen: die HiKam S6. --------------------------------------------- https://sec-consult.com/de/blog/detail/hikam-hi-ich-bin-nicht-deine-kamera/ ∗∗∗ Kleinanzeigenbetrug mit gefälschter Post-Website ∗∗∗ --------------------------------------------- Kriminelle verwenden eine gefälschte Post-Website www.post-service.online für Kleinanzeigenbetrug. Sie suchen nach hochpreisigen Angeboten und geben vor, den Kauf über einen erfundenen Kurierservice der Post abwickeln zu wollen. Ziel ist es, den Opfern das Geld aus der Tasche zu ziehen, denn in weiterer Folge werden Kreditkartendaten abgefragt und die Freigabe einer Zahlung verlangt. --------------------------------------------- https://www.watchlist-internet.at/news/kleinanzeigenbetrug-mit-gefaelschter… ===================== = Vulnerabilities = ===================== ∗∗∗ Löchrige UPnP-Umsetzung in alten Broadcom-SDKs macht Router angreifbar ∗∗∗ --------------------------------------------- Einige Routermodelle mit EoL-Status etwa von Linksys & Cisco sind dank Lücken in alten Broadcom-SDK-Versionen via UPnP angreifbar. Updates gibt es nicht. --------------------------------------------- https://heise.de/-6209100 ∗∗∗ Sicherheitsupdate: Angreifer könnten auf Dateien von Apache-Webservern zugreifen ∗∗∗ --------------------------------------------- Angreifer haben es derzeit auf Apache-Webserver abgesehen. Davon ist aber nur eine bestimmte Version bedroht. Die Path-Traversal-Lücke (CVE-2021-41773) betrifft ausschließlich die Apache-HTTP-Server-Version 2.4.49. --------------------------------------------- https://heise.de/-6209130 ∗∗∗ TYPO3-CORE-SA-2021-015: HTTP Host Header Injection in Request Handling ∗∗∗ --------------------------------------------- It has been discovered that TYPO3 CMS is susceptible to host spoofing due to improper validation of the HTTP Host header. TYPO3 uses the HTTP Host header, for example, to generate absolute URLs during the frontend rendering process. Since the host header itself is provided by the client, it can be forged to any value, even in a name-based virtual hosts environment. CVE-ID: CVE-2021-41114 --------------------------------------------- https://typo3.org/security/advisory/typo3-core-sa-2021-015 ∗∗∗ TYPO3-CORE-SA-2021-014: Cross-Site-Request-Forgery in Backend URI Handling ∗∗∗ --------------------------------------------- It has been discovered that the new TYPO3 v11 feature that allows users to create and share deep links in the backend user interface is vulnerable to cross-site-request-forgery. [...] To successfully carry out an attack, an attacker must trick his victim to access a compromised system. The victim must have an active session in the TYPO3 backend at that time. --------------------------------------------- https://typo3.org/security/advisory/typo3-core-sa-2021-014 ∗∗∗ Android Security Bulletin—October 2021 ∗∗∗ --------------------------------------------- The Android Security Bulletin contains details of security vulnerabilities affecting Android devices.

The PoC exploit targets CVE-2021-1810, a vulnerability that can lead to the bypass of all three protections that Apple implemented against malicious file downloads, namely file quarantine, Gatekeeper, and notarization. --------------------------------------------- https://www.securityweek.com/poc-exploit-released-macos-gatekeeper-bypass ∗∗∗ Boutique "Dark" Botnet Hunting for Crumbs ∗∗∗ --------------------------------------------- [...] But aside from these more visible botnets, there are smaller, "Boutique" botnets. They go after less common vulnerabilities and pick systems that the major botnets find not lucrative enough to go after. Usually, only a few vulnerable devices are exposed. Taking the animal analogy a bit too far: These are like crustaceans on the ocean floor living off what the predators above discard. One such botnet is "Dark Bot". --------------------------------------------- https://isc.sans.edu/diary/rss/27898 ∗∗∗ Expired Lets Encrypt Root Certificate Causes Problems for Many Companies ∗∗∗ --------------------------------------------- A root certificate used by Let’s Encrypt expired on September 30 and, despite being notified a long time in advance, many companies experienced problems. read more --------------------------------------------- https://www.securityweek.com/expired-lets-encrypt-root-certificate-causes-p… ∗∗∗ BazarLoader and the Conti Leaks ∗∗∗ --------------------------------------------- In July, we observed an intrusion that started from a BazarLoader infection and lasted approximately three days.

This year, the number is likely to be higher (13,002 by September 1). The problem with a zero-day vulnerability is that it remains a zero-day until it is patched by both the vendor and the user. --------------------------------------------- https://www.securityweek.com/telemetry-report-shows-patch-status-high-profi… ∗∗∗ The Ransomware Threat in 2021 ∗∗∗ --------------------------------------------- New research from Symantec finds that organizations face an unprecedented level of danger from targeted ransomware attacks as the number of adversaries multiply alongside an increased sophistication in tactics. --------------------------------------------- https://symantec-enterprise-blogs.security.com/blogs/threat-intelligence/ra… ∗∗∗ Facebook open-sources internal tool used to detect security bugs in Android apps ∗∗∗ --------------------------------------------- Facebook has open-sourced Mariana Trench, one of its internal security tools, used by its security teams for finding and fixing bugs in Android and Java applications. --------------------------------------------- https://therecord.media/facebook-open-sources-internal-tool-used-to-detect-… ∗∗∗ Ransomware attack disrupts hundreds of bookstores across France, Belgium, and the Netherlands ∗∗∗ --------------------------------------------- Hundreds of bookstores across France, Belgium, and the Netherlands have had their operations disrupted this week after a ransomware attack crippled the IT systems of TiteLive, a French company that operates a SaaS platform for book sales and inventory management. --------------------------------------------- https://therecord.media/ransomware-attack-disrupts-hundreds-of-bookstores-a… ∗∗∗ After the storm - how to move on with NTLM ∗∗∗ --------------------------------------------- I remember that, about 15 years ago, we already flagged the absence of SMB signing as a vulnerability in reports. Though at that time, we circled more around the theoretical risk of someone tampering SMB traffic due to the lack of integrity protection. None of us really had an idea how to make use of that vulnerability.
