CVE-2024-3408
📋 TL;DR
CVE-2024-3408 is a critical vulnerability in dtale versions 3.10.0 that allows attackers to bypass authentication and execute arbitrary code on the server. The vulnerability stems from a hardcoded SECRET_KEY in Flask configuration and insufficient input validation on custom filter queries. Organizations using dtale 3.10.0 for data visualization are affected.

📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete server compromise allowing attackers to execute arbitrary commands, steal sensitive data, install malware, or pivot to other systems in the network.
Likely Case
Attackers gain unauthorized access to the dtale application, execute arbitrary code to exfiltrate data, and potentially compromise the underlying server.
If Mitigated
Limited impact with proper network segmentation, but authentication bypass still possible if the application is exposed.
🎯 Exploit Status
Exploit details are publicly available in the referenced GitHub commit and bounty reports. The vulnerability is straightforward to exploit.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Versions after commit 32bd6fb4a63de779ff1e51823a456865ea3cbd13
Vendor Advisory: https://github.com/man-group/dtale/commit/32bd6fb4a63de779ff1e51823a456865ea3cbd13
Restart Required: Yes
Instructions:
1. Update dtale to the latest version using pip: pip install --upgrade dtale
2. Restart all dtale services
3. Verify the SECRET_KEY is no longer hardcoded and custom filter restrictions are properly enforced
🔧 Temporary Workarounds
Disable dtale service
linuxImmediately stop and disable dtale services to prevent exploitation
sudo systemctl stop dtale
sudo systemctl disable dtale
Network isolation
linuxRestrict network access to dtale instances using firewall rules
sudo iptables -A INPUT -p tcp --dport [dtale_port] -j DROP
🧯 If You Can't Patch
- Immediately disable dtale services and remove from production
- Implement strict network segmentation and firewall rules to isolate dtale instances
🔍 How to Verify
Check if Vulnerable:
Check if running dtale version 3.10.0: pip show dtale | grep VersionCheck Version:
pip show dtale | grep VersionVerify Fix Applied:
Verify dtale version is updated beyond 3.10.0 and check that SECRET_KEY is not hardcoded in configuration📡 Detection & Monitoring
Log Indicators:
- Unusual authentication attempts
- Requests to /update-settings endpoint with custom filter payloads
- Unexpected process execution from dtale
Network Indicators:
- Unusual outbound connections from dtale server
- Traffic patterns indicating data exfiltration
SIEM Query:
