CVE-2023-49675
📋 TL;DR
CVE-2023-49675 is an out-of-bounds write vulnerability in certain project file handling software. An unauthenticated attacker can trick users into opening malicious project files to execute arbitrary code or cause system crashes. This affects users who open untrusted project files from local or network sources.
💻 Affected Systems
- Specific software not named in provided references - check vendor advisory for details
⚠️ Manual Verification Required
This CVE does not have specific version information in our database, so automatic vulnerability detection cannot determine if your system is affected.
Why? The CVE database entry doesn't specify which versions are vulnerable (no version ranges provided by the vendor/NVD).

- Review the CVE details at NVD
- Check vendor security advisories for your specific version
- Test if the vulnerability is exploitable in your environment
- Consider updating to the latest version as a precaution
⚠️ Risk & Real-World Impact
Worst Case
Full system compromise with arbitrary code execution leading to data theft, ransomware deployment, or complete system control.
Likely Case
Application crashes and denial of service, with potential for limited code execution in user context.
If Mitigated
Application crash without code execution if exploit fails or security controls block payload execution.
🎯 Exploit Status
Exploitation requires social engineering to get user to open malicious file. No authentication required once file is opened.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown - check vendor advisory for specific fixed version
Vendor Advisory: https://cert.vde.com/en/advisories/VDE-2024-024
Restart Required: Yes
Instructions:
1. Identify affected software from vendor advisory
2. Download latest patched version from official vendor source
3. Install update following vendor instructions
4. Restart application or system as required
🔧 Temporary Workarounds
Restrict project file execution
allBlock execution of project files from untrusted sources using application controls
User awareness training
allTrain users not to open project files from unknown or untrusted sources
🧯 If You Can't Patch
- Implement application whitelisting to prevent unauthorized software execution
- Use endpoint protection with exploit prevention capabilities
🔍 How to Verify
Check if Vulnerable:
Check software version against vendor advisory. If running affected version and can open project files, system is vulnerable.Check Version:
Check application 'About' menu or use vendor-specific version check commandVerify Fix Applied:
Verify software version matches or exceeds patched version specified in vendor advisory.📡 Detection & Monitoring
Log Indicators:
- Application crash logs with memory access violations
- Unexpected process termination events
- File access to project files from unusual locations
Network Indicators:
- Downloads of project files from untrusted sources
- Internal file shares distributing project files
SIEM Query:
EventID=1000 OR EventID=1001 (Application crashes) AND ProcessName contains [affected_software]
