CVE-2023-48632
📋 TL;DR
Adobe After Effects has an out-of-bounds write vulnerability that allows attackers to execute arbitrary code when a user opens a malicious file. This affects users running After Effects versions 24.0.3 and earlier or 23.6.0 and earlier. Successful exploitation requires user interaction but could lead to full system compromise.
💻 Affected Systems
- Adobe After Effects
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete system takeover with attacker gaining the same privileges as the current user, potentially leading to data theft, ransomware deployment, or persistent backdoor installation.
Likely Case
Local privilege escalation leading to data exfiltration, credential harvesting, or installation of additional malware payloads.
If Mitigated
Limited impact with proper application sandboxing and user privilege restrictions, potentially only affecting the After Effects process.
🎯 Exploit Status
Exploitation requires user interaction (opening malicious file). No public exploit code available at time of analysis.
