CVE-2025-62266

CVE-2025-62266: Liferay Portal is vulnerable to DNS rebinding attacks

By default, Liferay Portal 7.4.0 through 7.4.3.119, and older unsupported versions, and Liferay DXP 2024.Q1.1 through 2024.Q1.5, 2023.Q4.0 through 2023.Q4.10, 2023.Q3.1 through 2023.Q3.10, 7.4 GA through update 92, and older unsupported versions is vulnerable to DNS rebinding attacks, which allows remote attackers to redirect users to arbitrary external URLs. This vulnerability can be mitigated by changing the redirect URL security from IP to domain.

Root Cause Analysis

The vulnerability lies in the way Liferay Portal handles redirects. The application was susceptible to DNS rebinding attacks, which could allow a remote attacker to redirect users to arbitrary external URLs. The root cause of the vulnerability was the use of unsafe methods to generate redirect URLs, such as PortalUtil.getCurrentURL(). These methods did not properly validate the domain of the redirect URL, allowing an attacker to specify a malicious domain that would be trusted by the application.

The patch addresses this vulnerability by replacing the unsafe redirect URL generation methods with PortletURLBuilder. This utility ensures that the redirect URL is properly constructed and validated, preventing DNS rebinding attacks. The identified vulnerable functions are those that were modified to use PortletURLBuilder or other safe redirect URL generation methods. These functions are directly involved in processing user input and generating redirect URLs, making them the primary targets for exploitation.
