Overview
CVE-2025-61691 is a serious vulnerability found in versions 8.53 and earlier of the VT STUDIO software. This flaw allows attackers to execute arbitrary code on the system by exploiting an out-of-bounds read vulnerability. Given the severity of potential consequences, including system compromise and data leakage, this issue merits prompt attention and action from affected users.

How the Exploit Works
The vulnerability resides in the way VT STUDIO handles certain files. If the software is manipulated into processing a specially crafted file, it could lead to an out-of-bounds read scenario. This could subsequently allow an attacker to execute arbitrary code on the system, compromising its integrity.
Conceptual Example Code
Here’s a conceptual example of how an attacker might exploit this vulnerability:
# Attacker creates a specially crafted file
echo "malicious_payload" > malicious_file.vts
# Attacker manipulates the victim to use the crafted file
./vtstudio --open malicious_file.vts
In this conceptual example, the attacker creates a malicious file (malicious_file.vts) and then tricks the user into opening this file using VT STUDIO. The software handles the specially crafted file in such a way that an out-of-bounds read error occurs, leading to the execution of the arbitrary code contained within the file.
Mitigation Guidance
Users affected by this vulnerability are strongly recommended to apply the vendor patch as soon as it is available. In the interim, employing a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) can serve as a temporary mitigation measure against potential exploits. Regular monitoring for suspicious activity should also be carried out to detect any possible system compromise.
