Under the cloak of UEFI Secure Boot: Introducing CVE-2024-7344
Under the cloak of UEFI Secure Boot: Introducing CVE-2024-7344
ESET researchers have discovered a vulnerability that allows bypassing UEFI Secure Boot, affecting the majority of UEFI-based systems. This vulnerability, assigned CVE-2024-7344, was found in a UEFI application signed by Microsoft’s Microsoft Corporation UEFI CA 2011 third-party UEFI certificate. Exploitation of this vulnerability leads to the execution of untrusted code during system boot, enabling potential attackers to easily deploy malicious UEFI bootkits (such as Bootkitty or BlackLotus) even on systems with UEFI Secure Boot enabled, regardless of the installed operating system.

Exploitation Walkthrough and Techniques - Ivanti Connect Secure RCE (CVE-2025-0282)
We agree - modern security engineering is hard - but none of this is modern. We are discussing vulnerability classes - with no sophisticated trigger mechanisms that fuzzing couldnt find - discovered in the 1990s, that can be trivially discovered via basic fuzzing, SAST (the things product security teams do with real code access). As an industry, should we really be communicating that these vulnerability classes are simply too complex for a multi-billion dollar technology company that builds enterprise-grade, enterprise-priced network security solutions to proactively resolve?

Ivanti Connect Secure VPN Exploitation Goes Global
Ivanti Connect Secure VPN Exploitation Goes Global
On January 10, 2024, Volexity publicly shared details of targeted attacks by UTA00178 exploiting two zero-day vulnerabilities (CVE-2024-21887 and CVE-2023-46805) in Ivanti Connect Secure (ICS) VPN appliances. On the same day, Ivanti published a mitigation that could be applied to ICS VPN appliances to prevent exploitation of these vulnerabilities. Since publication of these details, Volexity has continued to monitor its existing customers for exploitation. Volexity has also been contacted by multiple organizations that saw signs of compromise by way of mismatched file detections. Volexity has been actively working multiple new cases of organizations with compromised ICS VPN appliances.
