CVE-2024-55081
📋 TL;DR
An XML External Entity (XXE) injection vulnerability in Chat2DB's /datagrip/upload endpoint allows attackers to read arbitrary files, perform server-side request forgery, or execute arbitrary code by submitting malicious XML input. This affects all deployments of Chat2DB v0.3.5 with the vulnerable component enabled. Attackers can exploit this without authentication to potentially compromise the entire system.

- 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 server takeover.
Likely Case
Arbitrary file read leading to credential harvesting, configuration disclosure, and potential lateral movement within the environment.
If Mitigated
Limited impact with only error messages or partial data disclosure if XML parsing is restricted and external entity resolution is disabled.
🎯 Exploit Status
Public proof-of-concept demonstrates file read capabilities. The vulnerability requires no authentication and uses standard XXE techniques that are well-documented and easily weaponized.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not available
Vendor Advisory: Not available
Restart Required: No
Instructions:
No official patch available. Consider upgrading to a newer version if available, or implement workarounds.
🔧 Temporary Workarounds
Disable XXE Processing
allConfigure XML parser to disable external entity resolution
Modify XML parser configuration to set: XMLConstants.FEATURE_SECURE_PROCESSING = true
Set: http://apache.org/xml/features/disallow-doctype-decl = true
Set: http://xml.org/sax/features/external-general-entities = false
Set: http://xml.org/sax/features/external-parameter-entities = false
Disable Vulnerable Endpoint
allBlock or disable the /datagrip/upload endpoint
Add firewall rule to block access to /datagrip/upload
Configure web server to return 403 for /datagrip/upload paths
Modify application configuration to disable this endpoint
🧯 If You Can't Patch
- Implement network segmentation to isolate Chat2DB instances from sensitive systems
- Deploy a web application firewall (WAF) with XXE protection rules
🔍 How to Verify
Check if Vulnerable:
Test the /datagrip/upload endpoint with a crafted XXE payload that attempts to read /etc/passwd or similar system file. If the server returns file contents, it's vulnerable.Check Version:
Check Chat2DB version in application interface or configuration files. For containerized deployments: docker inspect <container> | grep -i versionVerify Fix Applied:
Retest with the same XXE payload after implementing fixes. The server should reject the request or return an error without disclosing file contents.📡 Detection & Monitoring
Log Indicators:
- Unusual XML payloads in /datagrip/upload requests
- Requests containing DOCTYPE declarations or external entity references
- Error messages related to XML parsing failures
Network Indicators:
- HTTP POST requests to /datagrip/upload with XML content containing external entity references
- Outbound connections from Chat2DB server to unexpected external systems
SIEM Query:
source="chat2db" AND (uri_path="/datagrip/upload" AND (request_body CONTAINS "<!DOCTYPE" OR request_body CONTAINS "SYSTEM" OR request_body CONTAINS "ENTITY"))
