CVE-2024-8061
📋 TL;DR
This vulnerability in aimhubio/aim version 3.23.0 allows denial of service attacks due to missing timeout configurations in external server communication methods. When the tracking server requests data from external resources without timeouts, it can hang indefinitely waiting for responses, blocking other legitimate requests. This affects anyone running the vulnerable aim tracking server version.

📦 What is this software?
Aim by Aimstack
⚠️ Risk & Real-World Impact
Worst Case
Complete denial of service where the tracking server becomes unresponsive to all requests, disrupting experiment tracking and monitoring capabilities indefinitely until manual intervention.
Likely Case
Partial service degradation where some server threads become stuck waiting for external responses, reducing available capacity and causing timeouts for legitimate users.
If Mitigated
Minimal impact with proper network segmentation and external service reliability, though some performance degradation may still occur during external service issues.
🎯 Exploit Status
Exploitation requires ability to control or influence external servers that the aim server communicates with, or to cause those servers to respond slowly/maliciously.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Version 3.23.1 or later
Vendor Advisory: https://huntr.com/bounties/c85d005c-b354-4c51-a88f-adda2f09622b
Restart Required: No
Instructions:
1. Update aim to version 3.23.1 or later using pip: 'pip install --upgrade aim==3.23.1' 2. Verify the update completed successfully 3. No restart required as fixes are applied during package update
🔧 Temporary Workarounds
Network timeout configuration
allConfigure network timeouts at the system or proxy level to limit how long external connections can remain open
External endpoint restriction
allRestrict which external servers the aim server can communicate with using firewall rules or network policies
🧯 If You Can't Patch
- Implement network segmentation to isolate aim server from untrusted external networks
- Deploy reverse proxy with strict timeout policies for all external communications
🔍 How to Verify
Check if Vulnerable:
Check aim version: 'pip show aim' or 'aim --version' and verify if version is exactly 3.23.0Check Version:
aim --version 2>/dev/null || pip show aim | grep VersionVerify Fix Applied:
After updating, verify version is 3.23.1 or later: 'pip show aim | grep Version' should show 3.23.1+📡 Detection & Monitoring
Log Indicators:
- Long-running external API calls in aim logs
- Increased error rates or timeouts in application monitoring
- Stuck threads in server monitoring
Network Indicators:
- Unusually long TCP connections to external servers from aim host
- Multiple hanging HTTP requests to external endpoints
