ESET on Friday announced patches for two local privilege escalation vulnerabilities affecting multiple Windows and macOS products.
The Windows products, the company warns in an advisory, were found vulnerable to CVE-2024-7400, a high-severity bug affecting the file operations handling during the removal of a detected file.
An attacker with low privileges on a system running an affected ESET product could exploit the flaw to delete arbitrary files and escalate privileges.
“ESET fixed the issue in the Cleaner module 1251, which was distributed automatically to ESET customers along with Detection engine updates. No action stemming from this advisory is required to be taken by ESET customers,” the company says.
ESET notes that the security defect impacts multiple end-user and enterprise products, including antivirus, internet security, and server security solutions.
The patched Cleaner module was released to all users on August 13. Those who do not regularly update their ESET products are advised to apply the fixes as soon as possible.
The cybersecurity firm credited Dmitriy Zuzlov of Positive Technologies for discovering and reporting the vulnerability.
“To the best of our knowledge, there are no existing exploits that take advantage of this vulnerability in the wild,” ESET notes.
On Friday, the company also announced patches for CVE-2024-6654, a medium-severity bug affecting ESET Cyber Security versions 7.0 to 7.4.1600.0, and Endpoint Antivirus for macOS (now Endpoint Security for macOS) versions 7.0 – 7.5.50.0.
The flaw, ESET says, could have allowed a low-privileged user to plant a symlink to a specific location, thus preventing the company’s security tools from running properly.
The issue “enables a user logged on to the system to perform a denial-of-service attack, which could be misused to disable the protection of the ESET security product and cause general system slow-down”, the company says.
ESET addressed the vulnerability in Cyber Security version 7.5.74.0 and Endpoint Security for macOS version 8.0.7200.0 and notes that it is not aware of any in-the-wild exploitation attempts.
“Note that as of version 8 there is a single product for ESET’s business customers on the macOS platform, named ESET Endpoint Security for macOS,” ESET points out.
