CVE-2024-47423
📋 TL;DR
Adobe Framemaker versions 2020.6, 2022.4 and earlier contain an unrestricted file upload vulnerability (CWE-434) that could allow arbitrary code execution. An attacker could exploit this by tricking a user into uploading a malicious file that gets automatically processed. This affects users of vulnerable Adobe Framemaker versions who interact with untrusted files.
💻 Affected Systems
- Adobe Framemaker
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Full system compromise with attacker gaining code execution at the user's privilege level, potentially leading to data theft, ransomware deployment, or lateral movement.
Likely Case
Local privilege escalation or malware installation on the victim's workstation when a user opens a malicious file.
If Mitigated
Limited impact with proper application sandboxing and user awareness preventing malicious file execution.
🎯 Exploit Status
Exploitation requires user interaction (opening a malicious file) but the technical complexity appears low based on the vulnerability type.
