CVE-2024-47656: Shilpi Client Dashboard Auth Bypass Flaw

CVE-2024-47656 Overview

CVE-2024-47656 is a critical authentication vulnerability in Shilpi Client Dashboard that allows remote attackers to bypass authentication controls through brute force attacks. The vulnerability stems from missing restrictions for incorrect login attempts on the API-based login endpoint, enabling attackers to systematically guess user credentials without any rate limiting or account lockout mechanisms.

Critical Impact

Remote attackers can gain unauthorized access to user accounts by conducting brute force attacks against the API login endpoint, potentially compromising sensitive data and user privacy across the entire platform.

Technical Details for CVE-2024-47656

Vulnerability Analysis

This vulnerability is classified as CWE-307 (Improper Restriction of Excessive Authentication Attempts). The Shilpi Client Dashboard application fails to implement proper rate limiting or account lockout mechanisms on its API-based login endpoint. This design flaw allows attackers to make an unlimited number of authentication attempts without triggering any defensive measures.

The network-accessible nature of this vulnerability means any remote attacker can target the login API without requiring prior authentication or user interaction. The lack of complexity in exploitation makes this particularly dangerous, as automated tools can rapidly cycle through common passwords or credential lists to compromise accounts.

Root Cause

The root cause of CVE-2024-47656 lies in the absence of authentication throttling controls within the Shilpi Client Dashboard API. The application does not track failed login attempts per user or source IP address, nor does it implement progressive delays, CAPTCHA challenges, or temporary account lockouts after repeated failures. This missing security control is a fundamental authentication design flaw that leaves the system vulnerable to automated credential attacks.

Attack Vector

The attack vector for this vulnerability is network-based, requiring no authentication or user interaction. An attacker can exploit this vulnerability by:

1. Identifying the API login endpoint of a target Shilpi Client Dashboard installation
2. Automating authentication requests with common username/password combinations
3. Iterating through credential lists without encountering rate limits or lockouts
4. Successfully authenticating once valid credentials are discovered
5. Gaining full access to the compromised user account and associated data

The vulnerability allows attackers to target multiple user accounts simultaneously, potentially compromising the entire user base of an affected installation. Tools like Hydra, Burp Suite Intruder, or custom scripts can easily automate this attack process.

Detection Methods for CVE-2024-47656

Indicators of Compromise

• High volume of failed authentication attempts from single or multiple IP addresses against the API login endpoint
• Unusual login patterns such as sequential username enumeration attempts
• Successful authentication following multiple failed attempts from the same source
• API login requests at abnormal rates or outside typical business hours
• Multiple accounts experiencing authentication failures within short time windows

Detection Strategies

• Implement monitoring for authentication failure rates exceeding baseline thresholds
• Deploy web application firewall (WAF) rules to detect and alert on brute force patterns
• Enable detailed logging of all API authentication attempts including source IP, timestamp, and username
• Configure SIEM rules to correlate failed login attempts and detect credential stuffing campaigns
• Monitor for automated request patterns such as consistent timing intervals or missing typical browser headers

Monitoring Recommendations

• Establish baseline metrics for normal authentication failure rates and alert on deviations
• Configure real-time alerting for accounts experiencing repeated authentication failures
• Monitor network traffic to the API login endpoint for unusual volume spikes
• Review authentication logs regularly for evidence of systematic credential testing
• Implement geolocation-based monitoring to detect login attempts from unexpected regions

How to Mitigate CVE-2024-47656

Immediate Actions Required

• Contact Shilpisoft for information on available patches or security updates
• Deploy a web application firewall (WAF) with rate limiting rules in front of the application
• Implement IP-based throttling at the network perimeter to limit authentication attempts
• Enforce strong password policies and encourage or require multi-factor authentication (MFA)
• Review authentication logs for evidence of prior exploitation attempts

Patch Information

No vendor patch information is currently available in the CVE data. Organizations should consult the CERT-IN Vulnerability Note CIVN-2024-0313 for the latest guidance from CERT-IN and contact Shilpisoft directly for remediation options.

Workarounds

• Deploy a reverse proxy or WAF with rate limiting to restrict login attempts per IP address
• Implement CAPTCHA or challenge-response mechanisms on the login page if application configuration allows
• Restrict access to the login API to known IP ranges using network-level controls
• Enable multi-factor authentication if supported by the application
• Consider temporarily restricting remote access to the application until a patch is available

# Example nginx rate limiting configuration
# Limit authentication attempts to 5 requests per minute per IP
limit_req_zone $binary_remote_addr zone=login_limit:10m rate=5r/m;

location /api/login {
    limit_req zone=login_limit burst=3 nodelay;
    limit_req_status 429;
    # Additional proxy configuration
}
