Gadget Inspector: Unmasking Reflected XSS in Liferay Portal

Vulnerability ID: CVE-2025-62249
CVSS Score: 6.9
Published: 2025-10-21

A Reflected Cross-Site Scripting (XSS) vulnerability exists in the google_gadget component of Liferay Portal and Liferay DXP. This flaw allows unauthenticated remote attackers to inject arbitrary JavaScript into the victim's browser session by tricking them into clicking a crafted link. While often dismissed as 'just XSS,' in the context of an enterprise portal, this can lead to total administrative compromise.

TL;DR

Legacy code bites back. The google_gadget component in Liferay Portal contains a Reflected XSS vulnerability (CVE-2025-62249). Attackers can craft malicious URLs that, when visited by a user (like an Admin), execute JavaScript in their session. This bypasses CSRF protections and can lead to account takeover. Patch immediately to version 7.4.3.133 or higher.

Technical Details

  • Attack Vector: Network (Reflected XSS)
  • CVSS v4.0: 6.9 (Medium)
  • CWE: CWE-79 (Improper Neutralization of Input)
  • Privileges Required: None (PR:N)
  • User Interaction: Required (Phishing/Link Click)
  • EPSS Score: 0.04% (Low Probability)

Affected Systems

  • Liferay Portal 7.4.0 - 7.4.3.132
  • Liferay DXP 2025.Q3.0 - 2025.Q3.2
  • Liferay DXP 2024.Q4.0 - 2024.Q4.7
  • Liferay DXP 2023.Q4.0 - 2023.Q4.10
  • Liferay Portal: 7.4.0 - 7.4.3.132 (Fixed in: 7.4.3.133)
  • Liferay DXP 2025: 2025.Q3.0 - 2025.Q3.2 (Fixed in: Next Quarterly Release)

Mitigation Strategies

  • Update Liferay Portal/DXP to the latest patched version.
  • Implement a strict Content Security Policy (CSP) to block inline scripts.
  • Deploy WAF rules to filter XSS payloads targeting the google_gadget component.

Remediation Steps:

  1. Identify current Liferay version (e.g., via Control Panel or patching tool).
  2. Download the latest cumulative patch or update pack from Liferay Help Center.
  3. Backup the database and file system.
  4. Apply the patch using the Liferay Patching Tool.
  5. Restart the Liferay service and verify the google_gadget component behavior.
