CVE-2025-45479
📋 TL;DR
This vulnerability allows attackers to execute arbitrary code on educoder challenge containers by injecting malicious content. It affects all users of educoder challenges v1.0 who create or interact with containers in the platform. The high CVSS score indicates critical impact potential.
💻 Affected Systems
- educoder challenges
📦 What is this software?
Challenges by Educoder
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise allowing attackers to execute arbitrary commands, access sensitive data, pivot to other systems, and potentially take full control of the hosting environment.
Likely Case
Unauthorized code execution within container environments, data exfiltration from challenge containers, and potential lateral movement within the educoder platform infrastructure.
If Mitigated
Limited impact with proper container isolation, input validation, and security controls preventing successful injection and execution.
🎯 Exploit Status
Exploitation requires access to create or modify containers in the educoder platform. The CWE-94 (Code Injection) nature suggests straightforward exploitation once access is obtained.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not available
Vendor Advisory: https://www.educoder.net/
Restart Required: No
Instructions:
1. Monitor educoder.net for official patches or updates. 2. Check the GitHub repository for any security fixes. 3. Apply any available updates immediately when released.
🔧 Temporary Workarounds
Input Validation and Sanitization
allImplement strict input validation and sanitization for all container creation/modification inputs
# Implement input validation in container creation code
# Sanitize all user inputs before processing
Container Isolation Enhancement
linuxStrengthen container isolation using security profiles and restricted capabilities
# Use Docker security options: --security-opt=no-new-privileges
# Implement seccomp profiles and AppArmor/SELinux policies
🧯 If You Can't Patch
- Disable container creation functionality until patch is available
- Implement network segmentation to isolate educoder challenge containers from critical systems
🔍 How to Verify
Check if Vulnerable:
Check if running educoder challenges v1.0. Test container creation with malicious input to see if code execution occurs.Check Version:
# Check educoder challenges version in application interface or configuration filesVerify Fix Applied:
After applying any available patches, test container creation with the same malicious input to confirm code execution is prevented.📡 Detection & Monitoring
Log Indicators:
- Unusual container creation patterns
- Suspicious commands executed within containers
- Failed container creation attempts with unusual input
Network Indicators:
- Unexpected outbound connections from container environments
- Unusual traffic patterns from educoder challenge containers
