CVE-2023-25879

7.8 HIGH

📋 TL;DR

Adobe Dimension versions 3.4.7 and earlier contain an improper input validation vulnerability that allows arbitrary code execution when a user opens a malicious file. This affects users of Adobe Dimension who open untrusted project files. Attackers can craft malicious files that exploit this vulnerability to run code on the victim's system.

💻 Affected Systems

Products:
  • Adobe Dimension
Versions: 3.4.7 and earlier
Operating Systems: Windows, macOS
Default Config Vulnerable: ⚠️ Yes
Notes: All installations of affected versions are vulnerable by default. No special configuration required for exploitation.

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Full system compromise with attacker gaining the same privileges as the current user, potentially leading to data theft, ransomware deployment, or persistent backdoor installation.

🟠

Likely Case

Local code execution allowing attackers to steal files, install malware, or pivot to other systems on the network.

🟢

If Mitigated

No impact if users only open trusted files from verified sources and proper endpoint security controls are in place.

🌐 Internet-Facing: LOW - Exploitation requires user interaction to open a malicious file, not directly exploitable over network.
🏢 Internal Only: MEDIUM - Internal users could be tricked into opening malicious files via phishing or shared drives.

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: UNKNOWN
Unauthenticated Exploit: ✅ No
Complexity: LOW

Exploitation requires user interaction (opening malicious file) but the vulnerability itself has low complexity once triggered.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: 3.4.8 or later

Vendor Advisory: https://helpx.adobe.com/security/products/dimension/apsb23-20.html

Restart Required: Yes

Instructions:

1. Open Adobe Creative Cloud application. 2. Navigate to 'Apps' section. 3. Find Adobe Dimension and click 'Update'. 4. Wait for download and installation to complete. 5. Restart Adobe Dimension.

🔧 Temporary Workarounds

Restrict file opening

all

Configure system policies to prevent opening of untrusted .dim files or restrict Adobe Dimension from opening files from untrusted sources.

Application control

all

Use application whitelisting to prevent execution of unauthorized code that might result from exploitation.

🧯 If You Can't Patch

  • Implement strict policies preventing users from opening .dim files from untrusted sources or email attachments.
  • Deploy endpoint detection and response (EDR) solutions to detect and block suspicious process execution patterns.

🔍 How to Verify

Check if Vulnerable:

Check Adobe Dimension version via Help > About Adobe Dimension. If version is 3.4.7 or earlier, system is vulnerable.

Check Version:

On Windows: Check version in Control Panel > Programs and Features. On macOS: Check version in Applications folder or via Adobe Creative Cloud app.

Verify Fix Applied:

Verify Adobe Dimension version is 3.4.8 or later via Help > About Adobe Dimension.

📡 Detection & Monitoring

Log Indicators:

  • Unusual process execution from Adobe Dimension
  • Creation of unexpected files or registry entries after opening .dim files
  • Network connections initiated by Adobe Dimension to suspicious destinations

Network Indicators:

  • Adobe Dimension making unexpected outbound connections
  • DNS queries for suspicious domains after file opening

SIEM Query:

process_name:"Adobe Dimension" AND (process_child_name:("cmd.exe", "powershell.exe", "wscript.exe") OR network_dest_ip:[suspicious_ips])
