Summary

A vulnerability in VaahCMS versions 2.0.0-2.3.4 involves a malicious obfuscated JavaScript payload embedded in the Blade template for OTP emails. The payload establishes a WebSocket connection to a C2 server, installs a password keylogger, scrapes WhatsApp Web DOM, and accepts remote commands to redirect or overwrite the page.

Risk Assessment

An attacker can capture passwords, steal data from WhatsApp Web, and hijack user sessions, leading to identity theft and leakage of sensitive information.

Recommendation

Immediately upgrade VaahCMS to version 2.3.5 or later, which removes the malicious code.

Original NVD description (English source)

VaahCMS versions 2.0.0 through 2.3.4 contain a malicious obfuscated JavaScript payload embedded in the Blade template responsible for rendering security OTP emails, allowing remote attackers to execute unauthorized code in any browser that renders the affected email template with JavaScript enabled. The payload establishes a WebSocket connection to a hardcoded command-and-control endpoint, installs a password-field keylogger using MutationObserver to capture dynamically added inputs, scrapes WhatsApp Web DOM content, and accepts remote commands to redirect or overwrite the rendered page.
