CVE-2024-12777
📋 TL;DR
This vulnerability in aimhubio/aim version 3.25.0 allows attackers to cause denial of service by exploiting the sshfs-client's lack of timeout settings. The single-threaded tracking server can be made unresponsive by requesting connections to unresponsive sockets, preventing legitimate requests. Organizations using aim for ML experiment tracking with sshfs functionality are affected.

📦 What is this software?
Aim by Aimstack
⚠️ Risk & Real-World Impact
Worst Case
Complete unavailability of the aim tracking server, disrupting ML experiment monitoring and data collection until manual intervention restarts the service.
Likely Case
Intermittent service degradation where the aim server becomes temporarily unresponsive to legitimate requests, requiring administrator attention.
If Mitigated
Minimal impact with proper network segmentation and monitoring that can detect and alert on service unavailability quickly.
🎯 Exploit Status
Exploitation requires network access to the aim tracking server and knowledge of sshfs endpoints. No authentication is needed to trigger the vulnerability.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Version 3.25.1 or later
Vendor Advisory: https://huntr.com/bounties/cdf8db79-c290-4fe5-9383-4c518bfba4a8
Restart Required: Yes
Instructions:
1. Update aim using pip: 'pip install --upgrade aim==3.25.1' 2. Restart the aim tracking server service 3. Verify the version with 'aim --version'
🔧 Temporary Workarounds
Network segmentation
linuxRestrict network access to aim tracking server ports to trusted sources only
Use firewall rules to limit access: iptables -A INPUT -p tcp --dport [aim_port] -s [trusted_ip] -j ACCEPT
iptables -A INPUT -p tcp --dport [aim_port] -j DROP
Disable sshfs functionality
allIf sshfs is not required, disable or remove sshfs-client usage in aim configuration
Modify aim configuration to remove sshfs endpoints or disable sshfs integration
🧯 If You Can't Patch
- Implement network monitoring to detect aim server unresponsiveness and alert administrators
- Deploy aim behind a reverse proxy with timeout settings and request limiting capabilities
🔍 How to Verify
Check if Vulnerable:
Check aim version: if version is exactly 3.25.0 and sshfs functionality is enabled, the system is vulnerableCheck Version:
aim --versionVerify Fix Applied:
Verify aim version is 3.25.1 or later using 'aim --version' command📡 Detection & Monitoring
Log Indicators:
- Extended hang times in aim server logs
- Timeout errors related to sshfs connections
- Increased error rates from aim tracking server
Network Indicators:
- Unusual connection patterns to aim sshfs endpoints
- Increased TCP connections to aim server without completion
