Remote Redirection Vulnerability in Liferay Portal

CVE-2024-25608

What is CVE-2024-25608?

CVE-2024-25608 is a remote redirection vulnerability found in Liferay Portal, a widely-used digital experience platform that facilitates the development of web applications. This vulnerability affects multiple versions of Liferay Portal, specifically versions 7.2.0 through 7.4.3.18 and earlier unsupported versions, as well as certain versions of Liferay DXP. The flaw allows attackers to exploit the HtmlUtil.escapeRedirect function, enabling them to redirect users to unauthorized external URLs. Such unauthorized redirection can expose organizations to various risks including phishing attacks, misinformation, and potential data theft.

Technical Details

The vulnerability arises from the improper handling of URL redirection parameters in Liferay Portal. Attackers can leverage the 'REPLACEMENT CHARACTER' (U+FFFD) to bypass the intended security measures designed to restrict redirection. This circumvention impacts several parameters including redirect, FORWARD_URL, and noSuchEntryRedirect. Due to this loophole, malicious actors can direct users to any external site, increasing the risk of further exploitation through social engineering tactics or malware distribution.

Potential Impact of CVE-2024-25608

1. Phishing Attacks: By redirecting users to malicious external websites, attackers can deceive individuals into providing sensitive information, such as login credentials, which can lead to unauthorized access to organizational systems.

2. Misinformation and Brand Damage: Unauthorized redirection could result in users being misled by attacking sites that mimic legitimate services, leading to potential reputation damage and loss of trust in the affected organization.

3. Malware Distribution: The vulnerability could be exploited to lead users to sites that host malicious content, which may result in the installation of malware on user systems, putting both organizational and client data at risk.
