CVE-2024-53320
📋 TL;DR
This CVE describes multiple stack buffer overflow vulnerabilities in Qualisys C++ SDK that could allow remote code execution. Attackers could exploit these flaws to crash applications or execute arbitrary code with the privileges of the vulnerable process. Organizations using Qualisys motion capture systems with the affected SDK are at risk.

⚠️ Risk & Real-World Impact
Worst Case
Remote attacker gains full control of the system running Qualisys software, potentially leading to data theft, system compromise, or lateral movement within the network.
Likely Case
Application crashes leading to denial of service for motion capture systems, disrupting operations in research, sports analysis, or entertainment production environments.
If Mitigated
With proper network segmentation and least privilege, impact is limited to the specific application instance, preventing system-wide compromise.
🎯 Exploit Status
Exploitation requires understanding of the SDK's API and ability to trigger the vulnerable functions with crafted input.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Version after commit a32a21a
Vendor Advisory: https://github.com/qualisys/qualisys_cpp_sdk/issues/47
Restart Required: No
Instructions:
1. Update to the latest Qualisys C++ SDK version. 2. Recompile any applications using the SDK. 3. Redeploy updated applications.
🔧 Temporary Workarounds
Input Validation
allImplement strict input validation for parameters passed to GetCurrentFrame, SaveCapture, and LoadProject functions
Stack Protection
allEnable compiler stack protection flags (/GS on Windows, -fstack-protector on Linux/macOS)
gcc -fstack-protector-all -o program source.cpp
cl /GS program.cpp
🧯 If You Can't Patch
- Isolate Qualisys systems on separate network segments with strict firewall rules
- Implement application whitelisting to prevent unauthorized code execution
🔍 How to Verify
Check if Vulnerable:
Check SDK version or commit hash against vulnerable commit a32a21aCheck Version:
Check SDK documentation or build configuration for version informationVerify Fix Applied:
Verify SDK version is newer than commit a32a21a and applications have been recompiled📡 Detection & Monitoring
Log Indicators:
- Application crashes with stack overflow errors
- Unusual memory access patterns in application logs
Network Indicators:
- Unusual network traffic to Qualisys application ports
- Large or malformed data packets to motion capture systems
