CVE-2022-29001
📋 TL;DR
SpringBootMovie versions 1.2 and earlier contain an arbitrary file upload vulnerability due to insufficient filtering of uploaded file suffixes. This allows attackers to upload malicious files to the server, potentially leading to remote code execution. Any system running the vulnerable SpringBootMovie application is affected.
💻 Affected Systems
- SpringBootMovie
📦 What is this software?
Springbootmovie by Springbootmovie Project
⚠️ Risk & Real-World Impact
Worst Case
Remote code execution leading to complete system compromise, data exfiltration, or ransomware deployment.
Likely Case
Webshell upload enabling persistent backdoor access, file system manipulation, and lateral movement.
If Mitigated
File uploads restricted to safe extensions only, preventing malicious file execution.
🎯 Exploit Status
Simple HTTP POST requests with malicious file uploads can exploit this vulnerability.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not available
Vendor Advisory: Not available
Restart Required: No
Instructions:
No official patch exists. Upgrade to a patched version if available, or implement workarounds.
🔧 Temporary Workarounds
Implement file extension validation
allAdd server-side validation to only allow specific safe file extensions (e.g., .jpg, .png, .pdf).
Modify SpringBootMovie source code to include file extension whitelisting in upload handlers.
Implement file content validation
allCheck file magic numbers or content types to ensure uploaded files match their extensions.
Add file signature validation in upload processing code.
🧯 If You Can't Patch
- Disable file upload functionality entirely in the application.
- Implement a Web Application Firewall (WAF) with rules to block malicious file uploads.
🔍 How to Verify
Check if Vulnerable:
Attempt to upload a file with a malicious extension (e.g., .jsp, .php) to the application's upload endpoint.Check Version:
Check application configuration or source code for version information.Verify Fix Applied:
Test that malicious file extensions are rejected and only allowed extensions are accepted.📡 Detection & Monitoring
Log Indicators:
- Unusual file uploads with executable extensions
- Multiple failed upload attempts
- Successful uploads of non-standard file types
Network Indicators:
- HTTP POST requests to upload endpoints with suspicious file names
- Traffic patterns indicating file upload exploitation
SIEM Query:
source="web_server" AND (url="*/upload*" AND (file_extension="jsp" OR file_extension="php" OR file_extension="exe"))
