CVE-2024-21663
📋 TL;DR
Discord-Recon, a Discord bot for bug bounty automation, is vulnerable to remote code execution (RCE) allowing attackers to execute shell commands on the server without admin privileges. This affects users running vulnerable versions of the bot, potentially compromising the host system and sensitive data. The vulnerability has been fixed in version 0.0.8.
💻 Affected Systems
- Discord-Recon
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Full compromise of the host system, leading to data theft, lateral movement, or deployment of malware.
Likely Case
Unauthorized access to execute arbitrary commands, potentially disrupting operations or stealing sensitive information.
If Mitigated
Limited impact if proper access controls and isolation are in place, but risk remains if exploited.
🎯 Exploit Status
Exploitation requires access to Discord commands but not admin roles, making it relatively easy for attackers with basic access.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 0.0.8
Vendor Advisory: https://github.com/DEMON1A/Discord-Recon/security/advisories/GHSA-fjcj-g7x8-4rp7
Restart Required: Yes
Instructions:
1. Update Discord-Recon to version 0.0.8 or later. 2. Restart the bot to apply the patch. 3. Verify the update by checking the version.
🔧 Temporary Workarounds
Restrict Discord Access
allLimit bot access to trusted users only by adjusting Discord server permissions.
Isolate Bot Environment
linuxRun the bot in a sandboxed or containerized environment to limit potential damage from RCE.
docker run --rm -it node:alpine
🧯 If You Can't Patch
- Disable or remove the Discord-Recon bot until patching is possible.
- Implement strict network segmentation and monitoring to detect and block exploitation attempts.
🔍 How to Verify
Check if Vulnerable:
Check the Discord-Recon version; if it's below 0.0.8, it is vulnerable.Check Version:
node -e "console.log(require('./package.json').version)" (run in bot directory)Verify Fix Applied:
After updating, confirm the version is 0.0.8 or higher and test that RCE commands no longer execute.📡 Detection & Monitoring
Log Indicators:
- Unusual shell command executions in bot logs
- Error messages related to command injection
Network Indicators:
- Suspicious outbound connections from the bot server
- Unexpected data exfiltration
