CVE-2024-53591: Seclore Auth Bypass Vulnerability

CVE-2024-53591 Overview

CVE-2024-53591 is an authentication bypass vulnerability affecting the login page of Seclore version 3.27.5.0. The vulnerability allows attackers to bypass authentication mechanisms via brute force attacks due to the absence of proper authorization controls and rate limiting on the login functionality.

Critical Impact

Successful exploitation allows attackers to gain unauthorized access to Seclore systems by repeatedly attempting authentication credentials without restriction, potentially compromising sensitive enterprise data protection mechanisms.

Affected Products

• Seclore version 3.27.5.0

Technical Details for CVE-2024-53591

Vulnerability Analysis

This vulnerability is classified as CWE-862 (Missing Authorization), indicating that the Seclore login page lacks proper access control mechanisms to prevent unauthorized authentication attempts. The absence of rate limiting or account lockout functionality allows attackers to systematically attempt password combinations without restriction.

The vulnerability affects the network-accessible login interface, requiring no prior authentication or user interaction to exploit. An attacker can launch automated brute force attacks against user accounts, attempting thousands of credential combinations until valid credentials are discovered. Once successful, the attacker gains full access to the compromised account's privileges within the Seclore platform.

Root Cause

The root cause of this vulnerability stems from missing authorization controls on the login functionality. Specifically, the application fails to implement:

• Rate limiting mechanisms to restrict the number of authentication attempts
• Account lockout policies after consecutive failed login attempts
• CAPTCHA or challenge-response mechanisms to distinguish human users from automated attacks
• IP-based blocking for suspicious authentication patterns

Attack Vector

The attack vector is network-based, targeting the Seclore web application's login page. Attackers can leverage automated tools to perform credential stuffing or dictionary-based brute force attacks. The exploitation process involves sending repeated authentication requests with different username and password combinations.

Since no code examples are available from verified sources, the attack methodology can be described as follows: An attacker identifies the Seclore login endpoint and uses automated tools to submit numerous authentication requests. The absence of lockout mechanisms allows unlimited attempts, making it feasible to discover valid credentials through systematic guessing or credential stuffing using breached password databases. Additional technical details can be found in the GitHub PoC Repository.

Detection Methods for CVE-2024-53591

Indicators of Compromise

• Unusually high volume of failed authentication attempts from single or multiple IP addresses
• Sequential login attempts using common username patterns or leaked credential lists
• Authentication logs showing rapid successive attempts against the same or different user accounts
• Successful login following a series of failed attempts from the same source

Detection Strategies

• Configure SIEM rules to alert on excessive failed login attempts within a short time window (e.g., more than 10 failed attempts in 5 minutes)
• Monitor web application firewall (WAF) logs for automated request patterns targeting the login endpoint
• Implement anomaly detection for login page traffic to identify brute force attack signatures
• Review authentication logs for successful logins following multiple failures from the same IP address

Monitoring Recommendations

• Enable detailed logging for all authentication events including timestamps, source IPs, and usernames
• Deploy network monitoring to track connections to the Seclore login interface
• Configure alerts for geographic anomalies in authentication attempts
• Establish baseline authentication patterns to detect deviations indicating attack activity

How to Mitigate CVE-2024-53591

Immediate Actions Required

• Implement account lockout policies to temporarily disable accounts after multiple consecutive failed login attempts
• Deploy rate limiting on the login endpoint to restrict authentication attempts per IP address
• Enable CAPTCHA or similar challenge-response mechanisms after initial failed attempts
• Review authentication logs for signs of compromise and reset credentials for potentially affected accounts

Patch Information

No vendor advisory or official patch information is currently available. Organizations should contact Seclore directly for guidance on available updates or patches. Monitor the GitHub PoC Repository for additional technical details about this vulnerability.

Workarounds

• Implement a Web Application Firewall (WAF) with brute force protection rules in front of the Seclore application
• Restrict access to the login page to known IP ranges using network-level access controls
• Enforce strong password policies and multi-factor authentication (MFA) to reduce brute force attack success rates
• Deploy an external authentication proxy with rate limiting capabilities

# Example WAF rate limiting configuration (conceptual)
# Implement rate limiting for login endpoint - limit to 5 requests per minute per IP
# Configure account lockout after 5 failed attempts with 15-minute lockout duration
# Enable CAPTCHA after 3 consecutive failed authentication attempts
