CVE-2024-3660

9.8 CRITICAL

📋 TL;DR

This CVE describes a critical arbitrary code injection vulnerability in TensorFlow's Keras framework that allows attackers to execute arbitrary code with the same permissions as the vulnerable application. Attackers can exploit this by providing a malicious model that triggers code execution regardless of the application's intended functionality. Any system running TensorFlow with Keras below version 2.13 is affected.

💻 Affected Systems

Products:
  • TensorFlow with Keras framework
Versions: All versions < 2.13
Operating Systems: All operating systems running TensorFlow
Default Config Vulnerable: ⚠️ Yes
Notes: Any application using TensorFlow's Keras framework to load models is vulnerable by default.

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Complete system compromise leading to data theft, ransomware deployment, lateral movement across networks, and persistent backdoor installation.

🟠

Likely Case

Remote code execution leading to data exfiltration, cryptocurrency mining, or botnet enrollment of vulnerable systems.

🟢

If Mitigated

Limited impact through network segmentation and strict input validation, potentially preventing successful exploitation.

🌐 Internet-Facing: HIGH
🏢 Internal Only: HIGH

🎯 Exploit Status

Public PoC: ⚠️ Yes
Weaponized: LIKELY
Unauthenticated Exploit: ⚠️ Yes
Complexity: LOW

Exploitation requires loading a malicious model file, which can be delivered through various vectors including compromised repositories or user uploads.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: TensorFlow 2.13 and later

Vendor Advisory: https://github.com/tensorflow/tensorflow/security/advisories

Restart Required: Yes

Instructions:

1. Identify all systems running TensorFlow < 2.13
2. Backup current models and configurations
3. Update TensorFlow to version 2.13 or later using pip: pip install --upgrade tensorflow
4. Restart all applications using TensorFlow
5. Validate that applications function correctly with updated version

🔧 Temporary Workarounds

Model Validation and Sanitization

all

Implement strict validation of model files before loading, including checks for suspicious patterns and digital signatures.

Network Segmentation

all

Isolate TensorFlow applications from sensitive networks and implement strict firewall rules.

🧯 If You Can't Patch

  • Implement strict input validation for all model loading operations
  • Run TensorFlow applications with minimal privileges and in isolated containers

🔍 How to Verify

Check if Vulnerable:

Check TensorFlow version: python -c "import tensorflow as tf; print(tf.__version__)" and verify if < 2.13

Check Version:

python -c "import tensorflow as tf; print(tf.__version__)"

Verify Fix Applied:

After update, run: python -c "import tensorflow as tf; print(tf.__version__)" and confirm version >= 2.13

📡 Detection & Monitoring

Log Indicators:

  • Unexpected model loading from untrusted sources
  • Process spawning from TensorFlow applications
  • Memory allocation patterns indicative of code injection

Network Indicators:

  • Outbound connections from TensorFlow applications to suspicious IPs
  • Unexpected data exfiltration patterns

SIEM Query:

source="tensorflow" AND (event="model_load" OR event="process_spawn") AND NOT source_ip IN trusted_ips
