CVE-2025-56748
📋 TL;DR
This vulnerability in Creativeitem Academy LMS allows attackers to brute-force password reset tokens due to predictable token generation and lack of rate limiting. Attackers can compromise user accounts by guessing valid reset tokens. All users of affected Academy LMS versions are at risk.
💻 Affected Systems

📦 What is this software?
Academy Lms by Creativeitem
⚠️ Risk & Real-World Impact
Worst Case
Mass account takeover leading to unauthorized access to all user accounts, potential data theft, and complete system compromise.
Likely Case
Targeted account compromise of specific users through automated brute-force attacks on password reset functionality.
If Mitigated
Limited impact with proper rate limiting and unpredictable token generation, reducing successful attacks to negligible levels.
🎯 Exploit Status
Exploitation requires only web access to password reset functionality and basic scripting knowledge for brute-force attacks.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Version 5.14 or later
Vendor Advisory: https://suryadina.com/academy-lms-reset-bruteforce-5q8w2e7t9y/
Restart Required: No
Instructions:
1. Download latest Academy LMS version from official source. 2. Backup current installation. 3. Replace files with patched version. 4. Verify functionality.
🔧 Temporary Workarounds
Implement Rate Limiting
allAdd rate limiting to password reset endpoint to prevent brute-force attacks
# Configure web server rate limiting (example for nginx):
limit_req_zone $binary_remote_addr zone=resetlimit:10m rate=5r/m;
location /password-reset {
limit_req zone=resetlimit burst=10 nodelay;
}
Web Application Firewall Rules
allDeploy WAF rules to detect and block password reset brute-force attempts
# Example ModSecurity rule:
SecRule REQUEST_URI "@contains /password-reset" \
"id:1001,phase:2,deny,status:429,t:lowercase,t:urlDecode,msg:'Password reset brute-force attempt'"
# Rate limiting rule for WAF
🧯 If You Can't Patch
- Implement strong rate limiting on password reset endpoints
- Monitor logs for excessive password reset attempts and block suspicious IPs
🔍 How to Verify
Check if Vulnerable:
Check if Academy LMS version is 5.13 or earlier. Test password reset token generation for predictability patterns.Check Version:
Check Academy LMS admin panel or version file in installation directoryVerify Fix Applied:
Verify installation is version 5.14 or later. Test that password reset tokens are cryptographically random and rate limiting is enforced.📡 Detection & Monitoring
Log Indicators:
- Multiple failed password reset attempts from single IP
- Rapid succession of password reset requests
- Unusual patterns in password reset token usage
Network Indicators:
- High volume of POST requests to password reset endpoint
- Patterned requests to /password-reset or similar endpoints
SIEM Query:
source="web_logs" AND (url="*/password-reset*" OR url="*/reset-password*") AND status=200 | stats count by src_ip | where count > 10
