CVE-2022-28841
📋 TL;DR
Adobe Bridge versions 12.0.1 and earlier contain an out-of-bounds write vulnerability that allows attackers to execute arbitrary code with the privileges of the current user. This requires the victim to open a malicious file, making it a client-side attack vector. All users running vulnerable versions of Adobe Bridge are affected.
💻 Affected Systems
- Adobe Bridge
📦 What is this software?
Bridge by Adobe
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise through arbitrary code execution with user privileges, potentially leading to data theft, ransomware deployment, or lateral movement within the network.
Likely Case
Malware installation or data exfiltration after a user opens a malicious file, with impact limited to the compromised user's permissions and system.
If Mitigated
No impact if users don't open untrusted files or if the application is patched, though social engineering could still bypass user awareness.
🎯 Exploit Status
Exploitation requires user interaction (opening a malicious file), making it less likely for widespread automated attacks but still dangerous via targeted phishing.
🛠️ Fix & Mitigation

🔧 Temporary Workarounds
Restrict File Opening
allPrevent users from opening untrusted files with Adobe Bridge by implementing application control policies.
Disable Adobe Bridge
allTemporarily disable or uninstall Adobe Bridge if not essential, reducing attack surface.
🧯 If You Can't Patch
- Implement strict user training to avoid opening untrusted files, especially from unknown sources.
- Use endpoint detection and response (EDR) tools to monitor for suspicious process execution from Adobe Bridge.
🔍 How to Verify
Check if Vulnerable:
Check Adobe Bridge version via Help > About Adobe Bridge; if version is 12.0.1 or earlier, it is vulnerable.Check Version:
On Windows: Check via application interface or registry. On macOS: Use 'defaults read /Applications/Adobe\ Bridge\ CC/Info.plist CFBundleShortVersionString' in terminal.Verify Fix Applied:
After updating, verify version is 12.0.2 or later in Help > About Adobe Bridge.📡 Detection & Monitoring
Log Indicators:
- Unusual process spawns from Adobe Bridge executable (e.g., Bridge.exe on Windows)
- File access logs showing malicious file extensions being opened
Network Indicators:
- Outbound connections from Adobe Bridge to unknown IPs post-file opening
SIEM Query:
Example: Process creation where parent process is 'Bridge.exe' and command line contains suspicious parameters.
