⚠️ Risk & Real-World Impact

🔴

Worst Case

Complete server compromise through malicious function execution, potentially leading to data corruption, privilege escalation, or remote code execution via crafted commands.

🟠

Likely Case

Unauthorized modification of game functions causing disruption, griefing, or unintended game behavior changes on affected servers.

🟢

If Mitigated

Limited impact with proper access controls and monitoring, though unauthorized file modifications could still occur.

🌐 Internet-Facing: HIGH
🏢 Internal Only: MEDIUM

🎯 Exploit Status

Public PoC: ⚠️ Yes
Weaponized: LIKELY
Unauthenticated Exploit: ⚠️ Yes
Complexity: LOW

Exploitation requires network access to the server but no authentication. The GitHub commit shows the specific authorization bypass.

🔧 Temporary Workarounds

Remove vulnerable mod

all

Temporarily remove the Command Block IDE mod until patched

mv /path/to/server/mods/command-block-ide-*.jar /path/to/backup/

Restrict network access

linux

Limit server access to trusted users only via firewall rules

iptables -A INPUT -p tcp --dport 25565 -s trusted_ip -j ACCEPT
iptables -A INPUT -p tcp --dport 25565 -j DROP

🧯 If You Can't Patch

  • Restrict server access to trusted users only via whitelist and firewall rules
  • Monitor function file modifications and server logs for unauthorized changes

🔍 How to Verify

Check if Vulnerable:

Check the mod version in server logs or mods folder; if Command Block IDE version is 0.4.9 or lower, the server is vulnerable.

Check Version:

grep -i 'command.block.ide' /path/to/server/logs/latest.log | head -5

Verify Fix Applied:

Confirm Command Block IDE version is 0.4.10 or higher in server startup logs or mod metadata.

📡 Detection & Monitoring

Log Indicators:

  • Unauthorized file modification attempts in server logs
  • Unexpected function file changes or errors

Network Indicators:

  • Unusual network traffic to server function endpoints
  • Requests to mod-specific API endpoints from untrusted sources

SIEM Query:

source="minecraft.log" "command.block.ide" AND ("modify" OR "write" OR "access")
