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.

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.

[...] 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.

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.
