CVE-2024-47443
📋 TL;DR
CVE-2024-47443 is an out-of-bounds write vulnerability in Adobe After Effects that could allow arbitrary code execution when a user opens a malicious file. This affects users running vulnerable versions of After Effects, potentially leading to full system compromise within the user's context.
💻 Affected Systems
- Adobe After Effects
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise with attacker gaining the same privileges as the logged-in user, enabling data theft, ransomware deployment, or persistent backdoor installation.
Likely Case
Malicious actors craft specially designed After Effects project files that, when opened, execute code to steal credentials, install malware, or encrypt files for ransom.
If Mitigated
With proper controls, impact is limited to the user's application sandbox without system-wide compromise, though user data within After Effects could still be accessed.
🎯 Exploit Status
Exploitation requires user interaction (opening malicious file). No public exploit code is currently available.
