CVE-2025-46384
📋 TL;DR
CVE-2025-46384 is an unrestricted file upload vulnerability (CWE-434) that allows attackers to upload malicious files to vulnerable systems. This could lead to remote code execution, data theft, or system compromise. The vulnerability affects web applications and services that accept file uploads without proper validation.
💻 Affected Systems
- Web applications with file upload functionality
⚠️ 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
Complete system compromise via remote code execution, data exfiltration, and persistent backdoor installation
Likely Case
Webshell deployment leading to unauthorized access, data manipulation, and lateral movement within the network
If Mitigated
Limited impact with proper file validation, but potential for denial of service through resource exhaustion
🎯 Exploit Status
File upload vulnerabilities are commonly exploited and require minimal technical skill when unauthenticated access is available
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: N/A
Vendor Advisory: https://www.gov.il/en/departments/dynamiccollectors/cve_advisories_listing?skip=0
Restart Required: No
Instructions:
1. Review application code for file upload handlers
2. Implement proper file validation including: file type verification, extension filtering, content scanning
3. Store uploaded files outside web root with proper permissions
4. Use unique, unpredictable filenames for uploaded files
🔧 Temporary Workarounds
Web Application Firewall Rules
allBlock malicious file uploads at the network perimeter
# Example WAF rule to block suspicious file uploads
# Block requests with Content-Type containing executable MIME types
SecRule REQUEST_HEADERS:Content-Type "@rx application/(x-msdownload|octet-stream|java-archive|vnd.microsoft.portable-executable)" "id:1001,phase:1,deny,status:403,msg:'Blocked malicious file upload'
File Upload Restriction
allRestrict file upload functionality to authenticated users only
# Example .htaccess rule for Apache
<FilesMatch "\.(php|phtml|php3|php4|php5|phps|pl|py|jsp|asp|sh|cgi)$">
Order Deny,Allow
Deny from all
</FilesMatch>
🧯 If You Can't Patch
- Implement strict file upload validation at the application layer
- Deploy network segmentation to isolate systems with file upload functionality
🔍 How to Verify
Check if Vulnerable:
Test file upload functionality by attempting to upload files with dangerous extensions (.php, .jsp, .exe) or malicious contentCheck Version:
N/A - This is a code-level vulnerability not tied to specific software versionsVerify Fix Applied:
Attempt to upload malicious files and verify they are rejected or properly sanitized📡 Detection & Monitoring
Log Indicators:
- Unusual file uploads with executable extensions
- Large number of failed upload attempts
- Uploads from unexpected IP addresses
Network Indicators:
- HTTP POST requests with executable file extensions in Content-Disposition headers
- Unusual traffic patterns to upload endpoints
SIEM Query:
source="web_server" AND (method="POST" AND uri="*upload*" AND (file_extension="php" OR file_extension="jsp" OR file_extension="exe"))
