CVE-2025-26918 is a critical vulnerability in Enituretechnology’s Small Package Quotes – Unishippers Edition, affecting versions up to 2.4.9. The vulnerability stems from improper neutralization of input during web page generation, leading to Reflected Cross-site Scripting (XSS). Attackers can inject malicious scripts into web pages viewed by users, which are then executed in the context of the victim’s browser. This can lead to unauthorized access, data theft, or session hijacking. The vulnerability is particularly dangerous because it requires minimal user interaction, such as clicking a crafted link. The CVSS 4.0 score reflects its critical severity due to the potential for widespread exploitation and significant impact on confidentiality, integrity, and availability.
DailyCVE Form:
Platform: Enituretechnology Small Package Quotes
Version: Up to 2.4.9
Vulnerability: Reflected XSS
Severity: Critical
Date: 03/03/2025
What Undercode Say:
Exploitation:
- Crafting Malicious Payloads: Attackers can inject JavaScript payloads into vulnerable input fields or URL parameters.
Example: ``
- Phishing Links: Send crafted links to victims via email or social engineering.
Example: `https://vulnerable-site.com/search?query=`
3. Session Hijacking: Use XSS to steal session cookies and impersonate users.
Example: ``
Protection:
- Input Sanitization: Implement strict input validation and sanitization to neutralize malicious scripts.
Example: Use libraries like DOMPurify or OWASP ESAPI.
- Content Security Policy (CSP): Enforce CSP headers to restrict script execution.
Example: `Content-Security-Policy: default-src ‘self’; script-src ‘self’;`
- Output Encoding: Encode user-generated content before rendering it in the browser.
Example: Use HTML entity encoding for special characters.
Commands and Tools:
- Scan for Vulnerabilities: Use tools like OWASP ZAP or Burp Suite to identify XSS flaws.
Command: `zap-cli quick-scan -s xss http://target-site.com`
2. Patch Management: Regularly update software to the latest version.Command: `sudo apt-get update && sudo apt-get upgrade
</h2>tail -f /var/log/apache2/access.log | grep -i “script”`

<h2 style="color: blue;">Command:
Code Examples:
1. Sanitization in PHP:
$input = htmlspecialchars($_GET[bash], ENT_QUOTES, 'UTF-8'); echo $input;
2. CSP Header in Apache:
Header set Content-Security-Policy "default-src 'self'; script-src 'self';"
3. Output Encoding in JavaScript:
function encodeHTML(str) {
return str.replace(/&/g, '&').replace(/</g, '<').replace(/>/g, '>');
}
By following these steps, organizations can mitigate the risks associated with CVE-2025-26918 and protect their systems from XSS attacks.
