How the mentioned CVE works:
The vulnerability exists in the Image Handler component within the /user/profile endpoint of yungifez Skuul School Management System versions up to 2.6.5. Attackers can remotely exploit this flaw by sending crafted HTTP requests to manipulate image processing parameters. This manipulation likely involves path traversal or insecure direct object references due to insufficient input validation and authorization checks. By exploiting these weaknesses, unauthorized users can bypass intended access controls and retrieve sensitive information such as user profile data. The publicly disclosed exploit demonstrates that simple network requests can lead to information disclosure without authentication. The vendor’s lack of response indicates the vulnerability remains unpatched, posing a consistent risk. The attack vector is network-based with low attack complexity, requiring no user interaction. The system fails to sanitize user input in image-related requests, allowing data leakage. This could expose personal identifiable information (PII) stored in the system. The CVSS score reflects a medium severity due to the confidentiality impact. The vulnerability underscores common web application security failures in access control mechanisms. Immediate risks include data breaches and privacy violations. Technical root cause may involve PHP code mishandling file paths or session permissions. Exploitation tools may include curl scripts or automated scanners. Administrators should monitor for anomalous requests to the affected endpoint. The flaw highlights the importance of secure coding practices in educational software. Without fixes, affected installations remain vulnerable to remote attacks.
Platform: yungifez Skuul School Management System

Prediction: Patch date unknown
What Undercode Say:
Analytics
curl -I http://target/user/profile
wget –spider http://target/user/profile?file=../../config.php
nmap -p 80 –script http-vuln-cve2025-13785 target.com
cat exploit_script.sh
!/bin/bash
Simple test for CVE-2025-13785
echo “Testing for information disclosure…”
curl -s “http://$1/user/profile?image=../../../etc/passwd”
how Exploit:
Remote attackers craft HTTP GET/POST requests to the /user/profile endpoint with manipulated parameters like ‘image’ or ‘id’ to traverse directories or access unauthorized data. Public exploits use tools like curl or custom scripts to send malicious requests, bypassing authentication and retrieving sensitive files or user information from the server.
Protection from this CVE
Update to patched version beyond 2.6.5 if released. Restrict access to /user/profile endpoint using web application firewalls (WAF). Implement input validation and proper authorization checks. Disable unnecessary image handling features. Monitor logs for unauthorized access attempts.
Impact:
Unauthorized information disclosure of sensitive user data, potential privacy breaches, compliance violations, and increased risk of further attacks leveraging exposed information.
