Hackers Exploit Roundcube Webmail Vulnerability to Steal Login Credentials

Cybersecurity threats are evolving, and one of the latest incidents involves a critical vulnerability in Roundcube Webmail. Recently, hackers have been attempting to exploit a cross-site scripting (XSS) flaw to steal user credentials. 🛡️💻

Researchers from Positive Technologies uncovered an email phishing campaign targeting a governmental organization in the Commonwealth of Independent States (CIS). This attack leverages CVE-2024–37383, a stored XSS vulnerability that allows attackers to execute arbitrary JavaScript in victims’ browsers. This flaw was patched in versions 1.5.7 and 1.6.7 of Roundcube as of May 2024.

📧 How the Attack Works:

Malicious Email: An email is sent, appearing as a blank message with an invisible attachment.JavaScript Execution: The email contains JavaScript that runs when the victim opens the email, loading malicious code to capture sensitive data.Credential Theft: A fake login form is displayed, tricking victims into entering their Roundcube credentials, which are then sent to a remote server. 🚨

While Roundcube may not be the most popular email client, its use among government agencies makes it a target for cybercriminals. Past vulnerabilities in Roundcube have been exploited by notorious hacking groups, highlighting the importance of robust security measures.
