CVE-2024-11795
📋 TL;DR
This vulnerability allows remote attackers to execute arbitrary code on Fuji Electric Monitouch V-SFT V8 installations by exploiting a stack-based buffer overflow during V8 file parsing. Attackers can achieve remote code execution by tricking users into opening malicious files or visiting malicious pages. Organizations using affected versions of Monitouch V-SFT are at risk.

Monitouch V Sft by Fujielectric
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise with attacker gaining full control of the affected system, potentially leading to data theft, system disruption, or lateral movement within the network.
Likely Case
Remote code execution in the context of the current user, allowing attackers to install malware, steal credentials, or pivot to other systems.
If Mitigated
Limited impact with proper network segmentation and user awareness preventing malicious file execution.
🎯 Exploit Status
Exploitation requires user interaction but the vulnerability is well-documented and stack-based buffer overflows are commonly weaponized.
