Overview Of The Zero-day Vulnerability Exploited
Table of Contents
CVE-2024-49138 is classified as an Elevation of Privilege (EoP) vulnerability, primarily stemming from a heap-based buffer overflow (CWE-122).
The Common Vulnerability Scoring System (CVSS) has assigned it a score of 7.8, indicating a high severity level.
Exploitation requires local access and has low attack complexity, making it particularly concerning for organizations with inadequate security measures in place.
The vulnerability can be exploited by crafting malicious CLFS log files. Attackers with local privileges can execute arbitrary code, thereby gaining full control over the affected system.
This could lead to unauthorized data access and further exploitation within an institution’s network.
A proof-of-concept (PoC) researcher MrAle98 released a proof-of-concept (PoC) exploit. The exploit, which targets a buffer overflow vulnerability in the CLFS.sys driver, has been successfully tested on Windows 11 23H2, enabling attackers to elevate privileges seamlessly.!Understanding the Threat
