New Flaw in Acer Laptops Could Let Attackers Disable Secure Boot Protection

New Flaw in Acer Laptops Could Let Attackers Disable Secure Boot Protection

Nov 29, 2022
Acer has released a firmware update to address a security vulnerability that could be potentially weaponized to turn off UEFI Secure Boot on affected machines. Tracked as  CVE-2022-4020 , the high-severity vulnerability affects five different models that consist of Aspire A315-22, A115-21, and A315-22G, and Extensa EX215-21 and EX215-21G. The PC maker described the vulnerability as an issue that "may allow changes to Secure Boot settings by creating NVRAM variables." Credited with  discovering  the flaw is ESET researcher Martin Smolár, who previously disclosed  similar bugs  in Lenovo computers. Disabling Secure Boot, an integrity mechanism that guarantees that only trusted software is loaded during system startup, enables a malicious actor to tamper with  boot loaders , leading to severe consequences. This includes  granting  the attacker complete control over the operating system loading process as well as "disable or bypass protections t...

5 Reasons Device Management Isn't Device Trust​

5 Reasons Device Management Isn't Device Trust​

Apr 21, 2025Endpoint Security / Zero Trust
The problem is simple: all breaches start with initial access, and initial access comes down to two primary attack vectors – credentials and devices. This is not news; every report you can find on the threat landscape depicts the same picture.  The solution is more complex. For this article, we'll focus on the device threat vector. The risk they pose is significant, which is why device management tools like Mobile Device Management (MDM) and Endpoint Detection and Response (EDR) are essential components of an organization's security infrastructure. However, relying solely on these tools to manage device risk actually creates a false sense of security. Instead of the blunt tools of device management, organizations are looking for solutions that deliver device trust . Device trust provides a comprehensive, risk-based approach to device security enforcement, closing the large gaps left behind by traditional device management solutions. Here are 5 of those limitations and how to ov...
