Protect Your Liferay Portal from Cross-Site Scripting Attacks

CVSScvssV3_1: 9.6

The Liferay Portal content management system is prone to cross-site scripting (XSS) attacks according to CVE-2024-26269. XSS vulnerabilities occur when malicious scripts are injected into otherwise trusted websites. Attackers can use XSS to steal user cookies, redirect users to malicious sites, or run arbitrary JavaScript code on vulnerable sites.

In this case, attackers could craft malicious links that include JavaScript code in the URL fragment identifier or “hash” portion of the link. When users visit pages containing these links, their browsers could potentially execute the embedded script code. This allows attackers to hijack user sessions or perform other malicious actions without the users’ knowledge or consent.

As a Liferay Portal administrator or user, there are some steps you can take to help prevent XSS attacks:

– Apply the latest software updates from Liferay to patch any known vulnerabilities. Versions and below are affected.

– Be cautious of any links or messages received from untrusted or unknown sources. Do not click on suspicious or unsolicited links.

– Use strong and unique passwords for your Liferay administrator and user accounts.

– Monitor your Liferay logs and sites for any unusual or suspicious activity. Be on alert for unauthorized changes or signs of account takeovers.

By keeping your Liferay software updated and practicing basic cybersecurity hygiene, you can help reduce your risk of exploitation from this and other cross-site scripting vulnerabilities. Staying vigilant about website security is important for protecting your data and users.
