CVE-2024-47656
📋 TL;DR
This vulnerability in Shilpi Client Dashboard allows remote attackers to bypass login attempt restrictions and perform brute force attacks against user passwords. Successful exploitation could lead to unauthorized access to user accounts. All systems running vulnerable versions of Shilpi Client Dashboard are affected.
💻 Affected Systems
- Shilpi Client Dashboard
📦 What is this software?
Client Dashboard by Shilpisoft
⚠️ Risk & Real-World Impact
Worst Case
Attackers gain administrative access to the dashboard, potentially compromising all user accounts and sensitive client data.
Likely Case
Attackers compromise regular user accounts to access confidential client information and dashboard functionality.
If Mitigated
Attackers are blocked after limited attempts, preventing account takeover while potentially causing temporary account lockouts.
🎯 Exploit Status
Brute force attacks require no authentication and can be automated with simple tools like Hydra or Burp Suite Intruder.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not specified in reference - check vendor advisory
Vendor Advisory: https://www.cert-in.org.in/s2cMainServlet?pageid=PUBVLNOTES01&VLCODE=CIVN-2024-0313
Restart Required: Yes
Instructions:
1. Check the CERT-IN advisory for patch details. 2. Apply the latest security update from Shilpi Client Dashboard vendor. 3. Restart the application/service. 4. Verify the fix by testing login attempt restrictions.
🔧 Temporary Workarounds
Implement Rate Limiting
allConfigure web server or application firewall to limit login attempts per IP address
# Example for nginx: limit_req_zone $binary_remote_addr zone=login:10m rate=5r/m;
# Then apply to login location: limit_req zone=login burst=10 nodelay;
Enable Account Lockout
allImplement temporary account lockout after failed login attempts
# Application-level configuration required
# Set lockout threshold (e.g., 5 attempts)
# Set lockout duration (e.g., 15 minutes)
🧯 If You Can't Patch
- Implement network-level restrictions to limit access to login API from trusted IPs only
- Deploy a WAF with brute force protection rules and enable CAPTCHA on login pages
🔍 How to Verify
Check if Vulnerable:
Test the login API endpoint with multiple failed authentication attempts from the same IP address. If no lockout or rate limiting occurs after 10+ attempts, the system is vulnerable.
Check Version:
Check application version through admin panel or configuration files. Specific command depends on deployment method.
Verify Fix Applied:
After patching, attempt multiple failed logins and verify that accounts lock or requests are rate limited. Monitor logs for blocked attempts.
📡 Detection & Monitoring
Log Indicators:
- Multiple failed login attempts from same IP address
- Unusual login patterns outside business hours
- Rapid succession of authentication failures
Network Indicators:
- High volume of POST requests to login endpoint
- Traffic patterns showing credential stuffing tools
- Requests with varying username/password combinations
