Reloader Vulnerability: Execution of Unsigned Software

CVE-2024-7344

What is CVE-2024-7344?

CVE-2024-7344 is a vulnerability found within the Reloader application developed by Howyar, which functions as a UEFI (Unified Extensible Firmware Interface) application for managing firmware settings and boot processes. This vulnerability specifically allows for the execution of unsigned software from a hardcoded path, which can lead to significant security risks. If exploited, this could enable adversaries to execute malicious software without proper authorization, potentially compromising the integrity and confidentiality of the affected systems.

Technical Details

The vulnerability resides in both the 32-bit and 64-bit versions of Howyar’s Reloader application. The primary flaw is associated with its insufficient enforcement of digital signature verification, permitting unsigned code to run in an inherently insecure manner. As a result, any malicious entity could exploit this gap to introduce harmful executables during the boot process or system operation, undermining system security and stability.

Potential Impact of CVE-2024-7344

1. Execution of Malicious Code: The ability for unsigned software to execute can lead to severe compromises, allowing attackers to install backdoors, rootkits, or other forms of malware that can disrupt normal operations.

2. Data Breach Risks: With unauthorized access to systems, sensitive data can be exfiltrated or tampered with, leading to potential data breaches and exposing organizations to legal and regulatory repercussions.

3. System Integrity Compromise: The integrity of the entire system can be at risk, as attackers could manipulate firmware settings and boot processes, potentially leading to persistent threats that are difficult to detect and mitigate.
