How the CVE Works:
CVE-2025-0342 is a cross-site scripting (XSS) vulnerability found in CampCodes Computer Laboratory Management System version 1.0. The issue resides in the `/class/edit/edit` file, specifically in the manipulation of the `s_lname` parameter. Attackers can inject malicious scripts into this parameter, which are then executed in the context of the victim’s browser when the page is rendered. This allows for unauthorized actions, such as stealing session cookies or redirecting users to malicious sites. The vulnerability is remotely exploitable, and while it is classified as medium severity, it poses significant risks if exploited in targeted attacks. Other parameters in the application may also be vulnerable to similar manipulation.
DailyCVE Form:
Platform: CampCodes
Version: 1.0
Vulnerability: Cross-Site Scripting (XSS)
Severity: Medium
Date: 01/09/2025
What Undercode Say:
Exploitation:
- Payload Injection: Attackers can craft malicious JavaScript payloads and inject them into the `s_lname` parameter.
Example: ``
- Remote Execution: The payload is executed when the victim views the affected page.
- Session Hijacking: Attackers can steal session cookies using
document.cookie.
Example: ``
Protection:
- Input Sanitization: Use libraries like DOMPurify to sanitize user inputs.
Example: `const cleanInput = DOMPurify.sanitize(userInput);`
- Content Security Policy (CSP): Implement CSP headers to restrict script execution.
Example: `Content-Security-Policy: default-src ‘self’; script-src ‘self’;`
- Output Encoding: Encode outputs to prevent script execution.
Example: Use `htmlspecialchars()` in PHP or `encodeURIComponent()` in JavaScript.
