How the Mentioned CVE Works:
CVE-2025-26775 is a critical vulnerability in RealMag777 BEAR, affecting versions from n/a through 1.1.4.4. It involves improper neutralization of input during web page generation, leading to Stored Cross-site Scripting (XSS). Attackers can inject malicious scripts into the application, which are then stored and executed when other users access the affected pages. This allows attackers to steal sensitive information, hijack sessions, or perform actions on behalf of the user. The vulnerability arises due to insufficient validation and sanitization of user-supplied input, which is then reflected in the web page output.
DailyCVE Form:
Platform: RealMag777 BEAR
Version: 1.1.4.4 and earlier
Vulnerability: Stored XSS
Severity: Critical
Date: 02/17/2025
What Undercode Say:
Exploitation:
1. Exploit Code Example:
<script>alert('XSS');</script>
Attackers can inject this script into input fields, which will be stored and executed when the page is loaded.
2. Exploit Command:
Use tools like Burp Suite or OWASP ZAP to intercept and modify HTTP requests, injecting malicious payloads into vulnerable parameters.
3. Automated Exploitation:
python3 exploit.py --url http://target.com --payload "<script>alert('XSS');</script>"
Protection:
1. Input Validation:
Implement strict input validation to ensure only expected data types and formats are accepted.
2. Output Encoding:
Use output encoding libraries to sanitize user input before rendering it in the browser.
echo htmlspecialchars($user_input, ENT_QUOTES, 'UTF-8');
3. Content Security Policy (CSP):
Add a CSP header to restrict the execution of inline scripts.
Content-Security-Policy: default-src 'self'; script-src 'self';
4. Patch Application:
Update RealMag777 BEAR to the latest version or apply the vendor-provided patch.
5. Security Headers:
Implement security headers like X-XSS-Protection and X-Content-Type-Options.
X-XSS-Protection: 1; mode=block X-Content-Type-Options: nosniff
6. Regular Security Audits:
Conduct regular security audits and penetration testing to identify and mitigate vulnerabilities.
7. Web Application Firewall (WAF):
Deploy a WAF to filter and block malicious requests.
8. Developer Training:
Train developers on secure coding practices to prevent XSS vulnerabilities.
9. Monitoring and Logging:
Monitor and log suspicious activities to detect potential exploitation attempts.
10. Third-party Libraries:
Ensure all third-party libraries are up-to-date and free from known vulnerabilities.
By following these steps, organizations can mitigate the risk posed by CVE-2025-26775 and protect their systems from Stored XSS attacks.
