CVE-2025-69243: Raytha CMS Information Disclosure Flaw

CVE-2025-69243 Overview

Raytha CMS contains a User Enumeration vulnerability in its password reset functionality. The application returns different response messages depending on whether a submitted login credential exists in the system or not. This behavioral difference allows attackers to systematically determine valid usernames, which can then be leveraged to conduct targeted brute force attacks against confirmed accounts.

User enumeration vulnerabilities are classified under CWE-204 (Observable Response Discrepancy) and represent a significant information disclosure weakness that undermines authentication security.

Critical Impact

Attackers can enumerate valid user accounts through the password reset feature, enabling targeted credential stuffing and brute force attacks against confirmed users.

Affected Products

• Raytha CMS versions prior to 1.5.0

Technical Details for CVE-2025-69243

Vulnerability Analysis

This vulnerability exists in Raytha CMS's password reset mechanism where the application provides observable differences in its response behavior based on whether the supplied username or email address corresponds to a valid account. When users attempt to reset a password, the system returns distinct messages for valid versus invalid accounts, creating a side-channel that leaks account existence information.

The root cause stems from improper implementation of the password reset workflow. Secure password reset implementations should return identical responses regardless of whether the account exists, preventing attackers from gleaning information about valid credentials.

Root Cause

The vulnerability originates from observable response discrepancy (CWE-204) in the password reset handler. The application fails to normalize its responses when processing password reset requests, allowing the response message or behavior to reveal whether an account exists in the database. This design flaw enables account enumeration without any authentication requirements.

Attack Vector

This vulnerability is exploitable over the network without requiring authentication or user interaction. An attacker can automate requests to the password reset endpoint with a list of potential usernames or email addresses and analyze the responses to determine which accounts are valid.

The attack workflow typically involves:

1. The attacker sends password reset requests with candidate usernames to the vulnerable endpoint
2. The application returns different messages for existing vs non-existing accounts
3. The attacker compiles a list of valid usernames based on response differences
4. Valid accounts are then targeted with credential stuffing or brute force attacks

No verified proof-of-concept code is publicly available for this vulnerability. For technical implementation details, refer to the CERT Advisory or the Raytha website.

Detection Methods for CVE-2025-69243

Indicators of Compromise

• Unusually high volume of password reset requests from a single IP address or IP range
• Sequential or pattern-based username submissions to the password reset endpoint
• Rapid succession of password reset attempts indicating automated enumeration
• Failed login attempts against accounts that were recently queried via password reset

Detection Strategies

• Implement rate limiting detection on the password reset endpoint to identify enumeration attempts
• Monitor for anomalous patterns in password reset request volumes and timing
• Configure web application firewall (WAF) rules to detect and block automated enumeration tools
• Analyze server logs for sequential or dictionary-based username patterns in reset requests

Monitoring Recommendations

• Enable detailed logging on authentication and password reset endpoints
• Set up alerts for threshold-based anomalies in password reset request frequency
• Track and correlate password reset attempts with subsequent brute force login attempts
• Monitor for known enumeration tool user-agent strings and request signatures

How to Mitigate CVE-2025-69243

Immediate Actions Required

• Upgrade Raytha CMS to version 1.5.0 or later immediately
• Implement rate limiting on the password reset endpoint as a defense-in-depth measure
• Review and audit authentication logs for signs of prior enumeration attempts
• Consider implementing CAPTCHA or similar anti-automation controls on the password reset form

Patch Information

This vulnerability was addressed in Raytha CMS version 1.5.0. Organizations should upgrade to this version or later to remediate the user enumeration weakness. The fix normalizes response messages in the password reset functionality to prevent information disclosure about account validity.

For additional information, consult the CERT Advisory and the official Raytha website.

Workarounds

• Deploy a web application firewall (WAF) with rules to detect and block enumeration patterns
• Implement rate limiting at the application or reverse proxy level for the password reset endpoint
• Add CAPTCHA challenges to the password reset form to impede automated enumeration
• Consider implementing account lockout policies after multiple failed password reset attempts for the same identifier

# Example rate limiting configuration for nginx
# Add to server or location block for password reset endpoint
location /password-reset {
    limit_req zone=password_reset burst=5 nodelay;
    limit_req_status 429;
    # ... existing configuration
}

# Define the rate limit zone in http block
# limit_req_zone $binary_remote_addr zone=password_reset:10m rate=5r/m;
