CVE-2022-28270
📋 TL;DR
Adobe Photoshop versions 22.5.6 and earlier, and 23.2.2 and earlier, contain an out-of-bounds write vulnerability in SVG file parsing. When exploited, this allows attackers to execute arbitrary code with the privileges of the current user. Exploitation requires the victim to open a malicious SVG file.
💻 Affected Systems
- Adobe Photoshop
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Full system compromise via arbitrary code execution with user privileges, potentially leading to data theft, ransomware deployment, or lateral movement.
Likely Case
Malicious actors trick users into opening crafted SVG files via phishing or compromised websites, leading to malware installation or credential theft.
If Mitigated
With proper patching and user awareness, impact is limited to isolated incidents from targeted attacks.
🎯 Exploit Status
Exploitation requires user interaction (opening malicious file). No public exploit code is known as of analysis.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Photoshop 22.5.7 and 23.3
Vendor Advisory: https://helpx.adobe.com/security/products/photoshop/apsb22-20.html
Restart Required: Yes
Instructions:
1. Open Adobe Creative Cloud application. 2. Navigate to 'Apps' tab. 3. Find Photoshop and click 'Update'. 4. Restart Photoshop after update completes.
🔧 Temporary Workarounds
Disable SVG file association
allPrevent Photoshop from automatically opening SVG files by changing file associations.
Windows: Control Panel > Default Programs > Associate a file type or protocol with a program > Change .svg to open with another application
macOS: Right-click SVG file > Get Info > Open with > Choose another application
User awareness training
allEducate users to avoid opening SVG files from untrusted sources.
🧯 If You Can't Patch
- Restrict user permissions to limit impact of code execution
- Implement application whitelisting to prevent unauthorized executables
