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. Two of these bugs, in particular, CVE-2021-28632 and CVE-2021-39840, are related Use-After-Free bugs even though they were patched months apart. Mark has graciously provided this detailed write-up of these vulnerabilities and their root cause. --------------------------------------------- https://www.thezdi.com/blog/2021/10/20/cve-2021-28632-amp-cve-2021-39840-by… ∗∗∗ ASEC Weekly Malware Statistics (October 11th, 2021 – October 17th, 2021) ∗∗∗ --------------------------------------------- The ASEC analysis team is using the ASEC automatic analysis system RAPIT to categorize and respond to known malware.

The vulnerability arises from the mishandling of URL-encoded path traversal characters in the HTTP GET request. Public proof-of-concept exploit code is widely available, and Apache and others have noted that this vulnerability is being exploited in the wild. While the original advisory indicated that CVE-2021-41773 was merely an information disclosure bug, both Rapid7 and community researchers have verified that the vulnerability can be used for remote code execution when mod_cgi is enabled. --------------------------------------------- https://www.rapid7.com/blog/post/2021/10/06/apache-http-server-cve-2021-417… ∗∗∗ Medtronics Insulin Pump Controllers Are Vulnerable to Hackers ∗∗∗ --------------------------------------------- The company just expanded its recall of insulin pump remote controllers that can be hijacked to alter insulin amounts.

This feature is disabled on default Windows 10 builds, but can be enabled in the Explorer menu under View→Preview pane. While this seems relatively simple at face value, it is anything but under the hood. For example, how does Windows know how to display the contents of certain filetypes but not others? Are the previews controlled by Explorer or is it done in another process? Are these handlers abusable? We spent a few days exploring preview handlers to gain a deeper understanding of how they work and answer these questions. --------------------------------------------- https://posts.specterops.io/life-is-pane-persistence-via-preview-handlers-3… ∗∗∗ CVE-2021-26420: Remote Code Execution in SharePoint via Workflow Compilation ∗∗∗ --------------------------------------------- In June of 2021, Microsoft released a patch to correct CVE-2021-26420 - a remote code execution bug in the supported versions of Microsoft SharePoint Server.

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.

Aber ungeschützte Systeme mit oder ohne Internetzugang sind ein Einfallstor für Hacker. Deshalb ist ein umfassendes Konzept für Endpoint Security für Unternehmen jeder Größe sehr wichtig. --------------------------------------------- https://www.zdnet.de/88397023/endpoint-security-ist-ueberall-gefragt/ ∗∗∗ New Atom Silo ransomware targets vulnerable Confluence servers ∗∗∗ --------------------------------------------- Atom Silo, a newly spotted ransomware group, is targeting a recently patched and actively exploited Confluence Server and Data Center vulnerability to deploy their ransomware payloads. --------------------------------------------- https://www.bleepingcomputer.com/news/security/new-atom-silo-ransomware-tar… ∗∗∗ Innovative Proxy Phantom ATO Fraud Ring Haunts eCommerce Accounts ∗∗∗ --------------------------------------------- The group uses millions of password combos at the rate of nearly 2,700 login attempts per second with new techniques that push the ATO envelope. --------------------------------------------- https://threatpost.com/proxy-phantom-fraud-ecommerce-accounts/175241/ ∗∗∗ PoC Exploit Released for macOS Gatekeeper Bypass ∗∗∗ --------------------------------------------- Rasmus Sten, a software engineer with F-Secure, has released proof-of-concept (PoC) exploit code for a macOS Gatekeeper bypass that Apple patched in April this year. 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.

NOBELIUM uses FoggyWeb to remotely exfiltrate the configuration database of compromised AD FS servers, decrypted token-signing certificate, and token-decryption certificate, as well as to download and execute additional components. --------------------------------------------- https://www.microsoft.com/security/blog/2021/09/27/foggyweb-targeted-nobeli… ∗∗∗ TLS 1.3 and SSL - the current state of affairs, (Tue, Sep 28th) ∗∗∗ --------------------------------------------- It has been over 3 years since the specification for TLS 1.3 was published, and although the protocol has some minor drawbacks, it is undoubtedly the most secure TLS version so far. One would therefore hope that the adoption of TLS 1.3 and its use on web servers around the globe would steadily increase over time (ideally hand in hand with a slow disappearance of older cryptographic protocols, especially the historic SSL 2.0 and SSL 3.0). --------------------------------------------- https://isc.sans.edu/diary/rss/27882 ∗∗∗ Securing mobile devices.

We also provide actionable recommendations any organization can adopt immediately to begin protecting their software supply chains in the cloud. --------------------------------------------- https://unit42.paloaltonetworks.com/cloud-threat-report-2h-2021/ ∗∗∗ Anatomy and Disruption of Metasploit Shellcode ∗∗∗ --------------------------------------------- In April 2021 we went through the anatomy of a Cobalt Strike stager and how some of its signature evasion techniques ended up being ineffective against detection technologies. In this blog post we will go one level deeper and focus on Metasploit, an often-used framework interoperable with Cobalt Strike. --------------------------------------------- https://blog.nviso.eu/2021/09/02/anatomy-and-disruption-of-metasploit-shell… ===================== = Vulnerabilities = ===================== ∗∗∗ ZDI-21-1116: NETGEAR R7800 net-cgi Out-Of-Bounds Write Remote Code Execution Vulnerability ∗∗∗ --------------------------------------------- This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of NETGEAR R7800 routers.

These data breaches, often involving sensitive or personal information, can cause financial loss to the victim organization and erode customer trust. --------------------------------------------- https://us-cert.cisa.gov/ncas/current-activity/2021/08/18/cisa-provides-rec… ∗∗∗ Cisco: Security devices are vulnerable to SNIcat data exfiltration technique ∗∗∗ --------------------------------------------- Networking equipment vendor Cisco said today that some of its security products fail to detect and stop traffic to malicious servers that abuse a technique called SNIcat to covertly steal data from inside corporate networks. --------------------------------------------- https://therecord.media/cisco-security-devices-are-vulnerable-to-snicat-dat… ===================== = Vulnerabilities = ===================== ∗∗∗ Cisco Security Advisories 2021-08-18 ∗∗∗ --------------------------------------------- 2 critical, 5 medium severity --------------------------------------------- https://tools.cisco.com/security/center/Search.x?publicationTypeIDs=1&secur… ∗∗∗ SSA-816035: Code Execution Vulnerability in SINEMA Remote Connect Client ∗∗∗ --------------------------------------------- The latest update for SINEMA Remote Connect Client fixes a vulnerability that could allow a local attacker to escalate privileges or even allow remote code execution under certain circumstances. --------------------------------------------- https://cert-portal.siemens.com/productcert/txt/ssa-816035.txt ∗∗∗ VMSA-2021-0017 ∗∗∗ --------------------------------------------- VMware Workspace ONE UEM console patches address a denial of service vulnerability (CVE-2021-22029) --------------------------------------------- https://www.vmware.com/security/advisories/VMSA-2021-0017.html ∗∗∗ Security updates for Thursday ∗∗∗ --------------------------------------------- Security updates have been issued by CentOS (exiv2, firefox, and thunderbird), Fedora (libsndfile, python-docx, and xscreensaver), openSUSE (haproxy), and SUSE (haproxy). --------------------------------------------- https://lwn.net/Articles/866753/ ∗∗∗ Positive Technologies helps to fix dangerous vulnerability in CODESYS ICS software ∗∗∗ --------------------------------------------- [...] This high-severity vulnerability (CVE-2021-36764) was discovered in the CODESYS V3 Runtime System software package (version 3.15.9.10). By exploiting it, an attacker can disable the PLC and disrupt the technological process. The vulnerability (NULL Pointer Dereference) was found in the CmpGateway component. An attacker with network access to the industrial controller can send a specially formed TCP packet and interrupt the operation of the PLC. Also, it has been found that this software contains another vulnerability (Local Privilege Escalation), which is currently being reviewed by the vendor. --------------------------------------------- https://www.ptsecurity.com/ww-en/about/news/positive-technologies-helps-to-… ∗∗∗ Red Hat JBoss Enterprise Application Platform: Schwachstelle ermöglicht Denial of Service ∗∗∗ --------------------------------------------- https://www.cert-bund.de/advisoryshort/CB-K21-0892 ∗∗∗ Internet Systems Consortium BIND: Schwachstelle ermöglicht Denial of Service ∗∗∗ --------------------------------------------- https://www.cert-bund.de/advisoryshort/CB-K21-0890 ∗∗∗ Kritische Schwachstellen in Altus Sistemas de Automacao Produkten ∗∗∗ --------------------------------------------- https://sec-consult.com/de/vulnerability-lab/advisory/kritische-schwachstel… ∗∗∗ Security Bulletin: IBM Cloud Pak for Multicloud Management Monitoring has applied security fixes for its use of Golang Go ∗∗∗ --------------------------------------------- https://www.ibm.com/blogs/psirt/security-bulletin-ibm-cloud-pak-for-multicl… ∗∗∗ Security Bulletin: Multiple vulnerabilities in IBM Java SDK affects WebSphere Application Server July 2021 CPU that is bundled with IBM WebSphere Application Server Patterns ∗∗∗ --------------------------------------------- https://www.ibm.com/blogs/psirt/security-bulletin-multiple-vulnerabilities-… ∗∗∗ Security Bulletin: Multiple Vulnerabilities in IBM® Java SDK affect WebSphere Application Server July 2021 CPU ∗∗∗ --------------------------------------------- https://www.ibm.com/blogs/psirt/security-bulletin-multiple-vulnerabilities-… ∗∗∗ Security Bulletin: IBM Cloud Pak for Multicloud Management Monitoring has applied security fixes for its use of Apache HttpClient ∗∗∗ --------------------------------------------- https://www.ibm.com/blogs/psirt/security-bulletin-ibm-cloud-pak-for-multicl… ∗∗∗ Security Bulletin: Multiple vulnerabilities may affect IBM® SDK, Java™ Technology Edition ∗∗∗ --------------------------------------------- https://www.ibm.com/blogs/psirt/security-bulletin-multiple-vulnerabilities-… ∗∗∗ Security Bulletin: Multiple vulnerabilities in IBM Java SDK affect IBM Security Directory Server ∗∗∗ --------------------------------------------- https://www.ibm.com/blogs/psirt/security-bulletin-multiple-vulnerabilities-… ∗∗∗ Linux kernel eBPF vulnerability CVE-2021-3490 ∗∗∗ --------------------------------------------- https://support.f5.com/csp/article/K43346111 -- CERT.at Daily mailing list Listinfo: https://lists.cert.at/cgi-bin/mailman/listinfo/daily
