CVE-2024-9362
📋 TL;DR
An unauthenticated directory traversal vulnerability in Polyaxon allows attackers to access sensitive files and directory information without authentication. This affects all systems running vulnerable versions of Polyaxon, potentially exposing configuration files, secrets, and system information. The vulnerability enables reading files from sensitive directories like /etc, leading to information disclosure.

- Consider updating to the latest version as a precaution
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise through exposure of secrets, credentials, and configuration files, potentially leading to lateral movement and data exfiltration.
Likely Case
Sensitive information disclosure including API keys, database credentials, configuration files, and system information that could enable further attacks.
If Mitigated
Limited information disclosure with proper network segmentation and access controls preventing access to critical systems.
🎯 Exploit Status
Unauthenticated exploitation with simple directory traversal techniques. No authentication required.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Latest patched version of Polyaxon
Vendor Advisory: https://huntr.com/bounties/d8dcb40f-ce76-4524-8d06-e0f12a07809d
Restart Required: No
Instructions:
1. Update Polyaxon to the latest patched version. 2. Follow vendor's update instructions. 3. Verify the fix is applied.
🔧 Temporary Workarounds
Network Access Restriction
allRestrict network access to Polyaxon instances to trusted IPs only
# Configure firewall rules to restrict access
# Example: iptables -A INPUT -p tcp --dport [POLYAXON_PORT] -s [TRUSTED_IP] -j ACCEPT
# iptables -A INPUT -p tcp --dport [POLYAXON_PORT] -j DROP
Reverse Proxy Input Validation
allImplement input validation and path sanitization at reverse proxy level
# Configure nginx/apache to block directory traversal patterns
# Example nginx: if ($request_uri ~* "\.\.") { return 403; }
🧯 If You Can't Patch
- Implement strict network segmentation and firewall rules to limit access to Polyaxon instances
- Deploy a WAF or reverse proxy with directory traversal protection rules enabled
🔍 How to Verify
Check if Vulnerable:
Test for directory traversal by attempting to access files like ../../etc/passwd via Polyaxon endpointsCheck Version:
Check Polyaxon version via API or configuration filesVerify Fix Applied:
Attempt the same directory traversal tests after patching; successful requests should be blocked📡 Detection & Monitoring
Log Indicators:
- HTTP requests containing ../ patterns
- Access to sensitive file paths in logs
- Unauthenticated requests to file access endpoints
Network Indicators:
- Unusual file path patterns in HTTP requests
- Requests to sensitive system directories
SIEM Query:
http.url:*../* AND (destination.port:[POLYAXON_PORT] OR destination.ip:[POLYAXON_IP])
