How the CVE Works:
CVE-2025-0341 is a critical vulnerability in CampCodes Computer Laboratory Management System 1.0. The issue resides in the `/class/edit/edit` file, specifically in the handling of the `e_photo` parameter. This parameter allows unrestricted file uploads, enabling attackers to upload malicious files remotely. The lack of proper validation and sanitization of the uploaded files can lead to remote code execution (RCE) or server compromise. The vulnerability has a CVSS score of 5.3 (Medium) and is exploitable over the network with low attack complexity. Publicly disclosed exploits increase the risk of widespread attacks.

What Undercode Say:
Exploitation:
1. Exploit Code Example:
import requests
url = "http://target.com/class/edit/edit"
files = {'e_photo': open('malicious.php', 'rb')}
response = requests.post(url, files=files)
print(response.text)
2. Exploit Steps:
- Craft a malicious file (e.g., PHP shell).
- Use the `e_photo` parameter to upload the file.
- Access the uploaded file to execute commands.
3. Exploit URL:
– `http://target.com/class/edit/edit`
Protection:
1. Input Validation:
– Validate file types and extensions.
– Use a whitelist of allowed file types.
2. File Sanitization:
– Rename uploaded files to prevent execution.
– Store files outside the web root.
3. Server Configuration:
– Disable execution permissions in upload directories.
– Use web application firewalls (WAFs) to block malicious uploads.
4. Patch Management:
– Update to the latest version of the software.
– Monitor vendor advisories for patches.
5. Code Example for Validation:
$allowed_types = ['image/jpeg', 'image/png'];
if (in_array($_FILES['e_photo']['type'], $allowed_types)) {
// Process file
} else {
die("Invalid file type.");
}
6. Tools for Detection:
– OWASP ZAP: Scan for file upload vulnerabilities.
– Burp Suite: Test for improper validation.

8. Monitoring:
– Use intrusion detection systems (IDS) to monitor upload directories.
– Log and review file upload activities regularly.
9. Mitigation Commands:
– Apache: `chmod -R 755 /var/www/uploads`
– Nginx: `location /uploads { deny all; }`
