HighCVSS 7.8Exploitation Probability (EPSS)
Low risk8th percentile - higher than 8% of all known CVEs
Summary
Substance3D - Stager is affected by a Stack-based Buffer Overflow vulnerability that could result in arbitrary code execution in the context of the current user. Exploitation requires user interaction in that a victim must open a malicious file.
Risk Assessment
An attacker can execute arbitrary code with the privileges of the user opening the malicious file, potentially leading to compromise of the application and user data.
Recommendation
Update Substance3D - Stager to the latest patched version. Avoid opening files from untrusted sources.
