CVE-2025-43807
📋 TL;DR
A stored cross-site scripting (XSS) vulnerability in Liferay Portal and DXP allows attackers to inject malicious scripts into the notifications widget via the publication 'Name' field. This affects Liferay Portal 7.4.0-7.4.3.112 and Liferay DXP 2023.Q4.0-2023.Q4.8, 2023.Q3.1-2023.Q3.10, and 7.4 GA-update 92. Attackers can execute arbitrary JavaScript in victims' browsers when they view the compromised notifications.
💻 Affected Systems
- Liferay Portal
- Liferay DXP
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attackers could steal session cookies, perform actions as authenticated users, redirect to malicious sites, or install malware via drive-by downloads.
Likely Case
Session hijacking, credential theft, or defacement of the notifications widget content.
If Mitigated
Limited impact if proper input validation and output encoding are enforced, though stored XSS remains a persistent threat.
🎯 Exploit Status
Exploitation requires authenticated access to inject payload; stored nature increases impact as it affects all users viewing the widget.
