Overview

This report details an identified vulnerability, CVE-2025-57392, within the BenimPOS Masaustu 3.0.x application. This security loophole is due to insecure file permissions that allow local users to modify .exe and .dll files, potentially leading to privilege escalation or arbitrary code execution. Any system or user that utilizes this application is at risk, and immediate action is required to mitigate potential data leakage or system compromise.

How the Exploit Works

The exploit works by taking advantage of the insecure file permissions granted to the Everyone and BUILTIN\Users groups in the BenimPOS Masaustu installation directory. These permissions enable local users to replace or modify .exe and .dll files. As the application is launched by another user or an elevated context, arbitrary code may be executed, leading to privilege escalation or even full system compromise.

Conceptual Example Code

Given the nature of this vulnerability, a conceptual example would involve the replacement of an .exe or .dll file. An attacker could use a simple command-line copy command to replace a legitimate .exe or .dll file with a malicious one:

COPY /Y C:\path\to\malicious\file.dll C:\Program Files\BenimPOS Masaustu\file.dll

This example assumes a malicious .dll file has already been crafted and placed into the path specified.
Please note that this is a simplified and conceptual example and actual exploit may be more complex.
