CVE-2024-9229
📋 TL;DR
This vulnerability allows unauthenticated attackers to cause a Denial of Service (DoS) by sending specially crafted HTTP requests with manipulated multipart boundaries to the file upload feature. Attackers can render the service unavailable by causing excessive resource consumption, affecting all users of the vulnerable system. This impacts any deployment of stangirard/quivr v0.0.298 with the file upload feature enabled.

⚠️ Risk & Real-World Impact
Worst Case
Complete service unavailability for all users, requiring server restart and potentially causing data loss or corruption during file uploads.
Likely Case
Temporary service degradation or unavailability until the malicious request is processed or the server is restarted.
If Mitigated
Minimal impact with proper request validation and resource limiting controls in place.
🎯 Exploit Status
Exploitation requires crafting HTTP requests with manipulated multipart boundaries, which is relatively straightforward for attackers with basic HTTP knowledge.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Version after v0.0.298 (check latest release)
Vendor Advisory: https://huntr.com/bounties/946a412d-422f-4623-bb1d-d2646ad23dfd
Restart Required: Yes
Instructions:
1. Update to the latest version of stangirard/quivr. 2. Verify the fix addresses multipart boundary validation. 3. Restart the application service.
🔧 Temporary Workarounds
Disable file upload feature
allTemporarily disable the vulnerable file upload functionality until patching is possible.
Configure application to disable file upload endpoints
Implement request size limits
allConfigure web server or application to limit request size and processing time.
nginx: client_max_body_size 10M;
Apache: LimitRequestBody 10485760
🧯 If You Can't Patch
- Implement WAF rules to block requests with malformed multipart boundaries
- Use rate limiting and request throttling to mitigate DoS impact
🔍 How to Verify
Check if Vulnerable:
Check if running stangirard/quivr version v0.0.298 and test file upload with manipulated multipart boundaries.Check Version:
Check application version in configuration or via application metadata endpointsVerify Fix Applied:
Verify updated to version after v0.0.298 and test that malformed multipart requests are properly rejected.📡 Detection & Monitoring
Log Indicators:
- Unusually long request processing times
- Multiple failed file upload attempts
- High CPU/memory usage spikes
Network Indicators:
- HTTP requests with malformed Content-Type headers
- Abnormally large or slow multipart requests
SIEM Query:
source="web_server_logs" AND (uri_path="/upload" OR uri_path LIKE "%/upload%") AND response_time > 10000
