CVE-2022-25794
📋 TL;DR
An out-of-bounds read vulnerability in Autodesk FBX Review version 1.5.2 and earlier allows attackers to execute arbitrary code or disclose information by tricking users into opening malicious ActionScript Byte Code (ABC) files. This affects users of Autodesk FBX Review software who open untrusted ABC files. The vulnerability could lead to full system compromise when combined with other exploits.

⚠️ Risk & Real-World Impact
Worst Case
Remote code execution with system-level privileges leading to complete system compromise, data theft, or ransomware deployment.
Likely Case
Information disclosure or application crash when opening malicious ABC files; code execution possible with additional exploit chaining.
If Mitigated
Limited to denial of service (application crash) if memory protections are enabled, but still poses information disclosure risk.
🎯 Exploit Status
Exploitation requires user interaction to open malicious file; may require additional vulnerabilities for reliable code execution as noted in description.

- Implement network segmentation to isolate systems running vulnerable software
🔍 How to Verify
Check if Vulnerable:
Check FBX Review version in application Help > About menu; versions 1.5.2 or earlier are vulnerable.Check Version:
Windows: wmic product where name='Autodesk FBX Review' get version
macOS: /Applications/Autodesk\ FBX\ Review.app/Contents/Info.plist | grep -A1 CFBundleShortVersionString
Linux: dpkg -l | grep fbx-review or rpm -qa | grep fbx-reviewVerify Fix Applied:
Verify version is 1.5.3 or later in Help > About menu; test with known safe ABC file to ensure proper parsing.📡 Detection & Monitoring
