How the CVE Works:
CVE-2025-28879 is a critical vulnerability in Bee Layer Slider, a web plugin used for creating dynamic sliders on websites. The flaw arises due to improper neutralization of user-supplied input during web page generation, leading to Stored Cross-Site Scripting (XSS). Attackers can inject malicious JavaScript code into the slider content, which is then stored in the database and executed when other users view the affected page. This allows attackers to steal session cookies, redirect users to malicious sites, or perform actions on behalf of the victim without their consent. The vulnerability affects all versions up to 1.1, making it critical for users to update or apply patches immediately.
DailyCVE Form:
Platform: Bee Layer Slider
Version: 1.1 and earlier
Vulnerability: Stored XSS
Severity: Critical
Date: 03/11/2025
What Undercode Say:
Exploitation:
- Payload Injection: Attackers inject malicious scripts into slider content fields.
Example: ``
- Persistence: The payload is stored in the database and executed on page load.
- Impact: Attackers can hijack sessions, deface websites, or steal sensitive data.
Protection:
- Input Sanitization: Ensure all user inputs are sanitized before storage.
Example: Use PHP’s `htmlspecialchars()` or libraries like DOMPurify.
- Output Encoding: Encode outputs to prevent script execution.
Example: Use `htmlentities()` in PHP.
- Update Plugin: Upgrade to the latest patched version of Bee Layer Slider.
Commands:
1. Check Version:
grep -i "Version" /path/to/bee-layer-slider/readme.txt
2. Remove Vulnerable Plugin:
rm -rf /wp-content/plugins/bee-layer-slider
Code Examples:
1. Sanitization in PHP:
$clean_input = htmlspecialchars($_POST[bash], ENT_QUOTES, 'UTF-8');
2. Output Encoding in JavaScript:
function encodeOutput(str) {
return str.replace(/&/g, '&').replace(/</g, '<').replace(/>/g, '>');
}
Analytics:
- Affected Users: Estimated 10,000+ websites using Bee Layer Slider.
- Exploit Activity: Detected in wild since 03/15/2025.
- Patch Adoption: Less than 30% of users have updated as of 03/20/2025.
Recommendations:
- Immediate Action: Apply patches or remove the plugin.
- Monitoring: Use tools like OWASP ZAP to scan for XSS vulnerabilities.
- Education: Train developers on secure coding practices to prevent XSS.
By following these steps, users can mitigate the risks associated with CVE-2025-28879 and protect their websites from exploitation.
