## Key facts

- **Exploitation phase:** Limited Exploitation. The vulnerability is known but shows very limited attacker interest or exploitation activity.
- **CVSS score:** 6.1
- **Public exploit available:** Yes
- **Affected products:** Liferay Portal, Liferay DXP
- **Weaknesses:** CWE-601 (URL Redirection to Untrusted Site ('Open Redirect'))
- **Tags:** web_application

## Description

HtmlUtil.escapeRedirect in Liferay Portal 7.2.0 through 7.4.3.18, and older unsupported versions, and Liferay DXP 7.4 before update 19, 7.3 before update 4, 7.2 before fix pack 19, and older unsupported versions can be circumvented by using the 'REPLACEMENT CHARACTER' (U+FFFD), which allows remote attackers to redirect users to arbitrary external URLs via the (1) 'redirect` parameter (2) `FORWARD_URL` parameter, (3) `noSuchEntryRedirect` parameter, and (4) others parameters that rely on HtmlUtil.escapeRedirect.

## CrowdSec analysis

[CVE-2024-25608](https://euvd.enisa.europa.eu/vulnerability/CVE-2024-25608) is a vulnerability in Liferay Portal and DXP that allows remote attackers to bypass URL redirection protections by exploiting the 'REPLACEMENT CHARACTER' (U+FFFD). By manipulating parameters such as 'redirect', 'FORWARD_URL', and others, attackers can redirect users to arbitrary external sites, potentially facilitating phishing attacks or malicious site redirections.

CrowdSec has been tracking this vulnerability and its exploits since 7th of January 2026.

Data from the CrowdSec community indicates that exploitation of CVE-2024-25608 is highly selective and intelligence-driven. Threat actors use advanced reconnaissance and carefully choose their targets, often as part of sophisticated campaigns or advanced persistent threat operations.
CrowdSec network telemetry also shows that exploitation of CVE-2024-25608 has significantly declined over the past week. Attack volumes are well below the long-term average, suggesting attackers are rapidly losing interest. The vulnerability appears to be falling out of active use across most threat landscapes.

Attackers exploit open redirect vulnerabilities by sending requests to endpoints like `/html/common/forward_jsp.jsp` with parameters such as `FORWARD_URL` containing crafted external URLs, often using special characters (e.g., U+FFFD) to bypass filters and redirect users to malicious sites.
