CVE-2024-51329
📋 TL;DR
A Host header injection vulnerability in Agile-Board 1.0 allows attackers to manipulate password reset links to steal reset tokens. This affects all users of Agile-Board 1.0 who use the password reset functionality. Attackers can use stolen tokens to reset user passwords and gain unauthorized access.
💻 Affected Systems
- Agile-Board
📦 What is this software?
Agile Board by Idrsdev
⚠️ Risk & Real-World Impact
Worst Case
Attackers gain administrative access by resetting admin passwords, leading to complete system compromise and data exfiltration.
Likely Case
Attackers reset regular user passwords to gain unauthorized access to accounts and sensitive project data.
If Mitigated
With proper network segmentation and monitoring, impact is limited to isolated user account compromise.
🎯 Exploit Status
Exploitation requires user interaction (clicking malicious link) but is technically simple. Public proof-of-concept exists in GitHub repositories.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: None available
Restart Required: No
Instructions:
No official patch available. Consider workarounds or migrating to alternative software.
🔧 Temporary Workarounds
Host Header Validation
allImplement strict validation of Host headers in web server configuration or application code.
# For Apache: SetEnvIf Host ^example\.com$ VALID_HOST
# For Nginx: if ($host !~* ^(example\.com|localhost)$) { return 444; }
Disable Password Reset
allTemporarily disable password reset functionality until a fix is available.
# Modify Agile-Board configuration to disable password reset feature
🧯 If You Can't Patch
- Implement web application firewall (WAF) rules to block malicious Host header patterns
- Monitor for unusual password reset activity and implement rate limiting
🔍 How to Verify
Check if Vulnerable:
Test by sending password reset request with manipulated Host header and checking if token is sent to attacker-controlled domain.Check Version:
Check Agile-Board version in application interface or configuration filesVerify Fix Applied:
Verify that password reset tokens are only sent to legitimate application domains regardless of Host header manipulation.📡 Detection & Monitoring
Log Indicators:
- Unusual Host header values in HTTP logs
- Multiple password reset requests from single IP
- Password reset attempts with suspicious referrers
Network Indicators:
- HTTP requests with manipulated Host headers
- Outbound connections to suspicious domains after password reset requests
SIEM Query:
source="web_logs" AND (Host!="*expected-domain*" OR Host="*malicious-domain*") AND uri="/password-reset*"
