CVE-2025-5321
📋 TL;DR
This critical vulnerability in aimhubio aim allows remote attackers to execute arbitrary code through improper input validation in the RestrictedPythonQuery function. Attackers can gain elevated privileges on affected systems. All users running aim versions up to 3.29.1 are affected.
💻 Affected Systems
- aimhubio aim
📦 What is this software?
Aim by Aimstack
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise allowing attackers to execute arbitrary code with elevated privileges, potentially leading to data theft, ransomware deployment, or persistent backdoor installation.
Likely Case
Unauthorized access to sensitive data, privilege escalation within the aim application, and potential lateral movement within the network.
If Mitigated
Limited impact with proper network segmentation and least privilege principles, potentially only affecting the aim application instance.
🎯 Exploit Status
Exploit code is publicly available on GitHub gist. Remote exploitation is possible without authentication.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: None available
Restart Required: Yes
Instructions:
1. Monitor aimhubio GitHub repository for security updates
2. Apply patch when available
3. Restart aim services after patching
🔧 Temporary Workarounds
Network Access Restriction
linuxRestrict network access to aim services to trusted IP addresses only
iptables -A INPUT -p tcp --dport [aim_port] -s [trusted_ip] -j ACCEPT
iptables -A INPUT -p tcp --dport [aim_port] -j DROP
Disable Vulnerable Component
allDisable or restrict access to the run_view Object Handler if not required
🧯 If You Can't Patch
- Isolate affected systems in a separate network segment with strict firewall rules
- Implement application-level WAF rules to block suspicious queries to the RestrictedPythonQuery endpoint
🔍 How to Verify
Check if Vulnerable:
Check aim version: aim --version. If version is 3.29.1 or lower, system is vulnerable.
Check Version:
aim --version
Verify Fix Applied:
After patching, verify version is above 3.29.1 and test RestrictedPythonQuery functionality with safe inputs.
