CVE-2025-62245: Liferay DXP CSRF Vulnerability

CVE-2025-62245 Overview

CVE-2025-62245 is a Cross-Site Request Forgery (CSRF) vulnerability [CWE-352] affecting Liferay Portal and Liferay Digital Experience Platform (DXP). The flaw resides in the publication comments functionality and allows remote attackers to add and edit publication comments on behalf of an authenticated user. Exploitation requires the victim to visit an attacker-controlled page or click a crafted link while authenticated to a vulnerable Liferay instance. The vendor advisory tracks the issue under the Liferay CVE-2025-62245 Advisory.

Critical Impact
Attackers can forge requests that add or modify publication comments in the context of an authenticated Liferay user, enabling content tampering and social engineering within the portal.

Affected Products

Liferay Portal 7.4.1 through 7.4.3.112
Liferay DXP 2023.Q4.0 through 2023.Q4.5, and 2023.Q3.1 through 2023.Q3.10
Liferay DXP 7.4 GA through update 92

Technical Details for CVE-2025-62245

Vulnerability Analysis

The vulnerability is a classic CSRF weakness in the publication comments feature of Liferay Portal and Liferay DXP. State-changing HTTP requests that add or edit publication comments do not adequately verify that the request originated from a legitimate, user-initiated action within the Liferay UI. As a result, a request generated by a third-party site can be replayed by the victim's browser using their active Liferay session cookies. The server processes the forged request as if the authenticated user had submitted it. User interaction is required, since the victim must load an attacker-controlled resource while logged in.

Root Cause

The root cause is missing or insufficient enforcement of anti-CSRF protections on the endpoints that handle publication comment creation and modification. Liferay's authentication token (p_auth) or an equivalent origin/referer check is either not required or not validated on the affected endpoints. Without a bound, unpredictable request token, the browser's same-origin trust model is not sufficient to prevent cross-origin invocation of these actions.

Attack Vector

Exploitation is network-based and does not require attacker credentials. The attacker crafts a malicious page containing an HTML form or JavaScript that issues a POST request to the vulnerable Liferay publication comment endpoint. When the authenticated victim visits the page, the browser attaches the Liferay session cookie and submits the forged request. The server executes the comment add or edit action under the victim's identity. Impact is limited to integrity of publication comment content; confidentiality and availability are not directly affected.

No public proof-of-concept exploit or exploit code is available for CVE-2025-62245 at this time. Refer to the Liferay CVE-2025-62245 Advisory for vendor-supplied technical details.

Detection Methods for CVE-2025-62245

Indicators of Compromise

Publication comment additions or edits attributed to users who did not intentionally interact with the comment feature.
HTTP POST requests to Liferay publication comment endpoints where the Referer or Origin header points to an external, untrusted domain.
Comment activity generated from IP addresses or user-agent strings that do not match the affected user's usual portal access patterns.

Detection Strategies

Review Liferay application and access logs for publication comment mutations correlated with cross-origin Referer headers or missing p_auth tokens.
Correlate publication comment audit events with user session activity to identify actions that occurred without corresponding portal navigation.
Deploy a web application firewall (WAF) rule that flags state-changing requests to Liferay comment endpoints lacking a valid same-origin Referer.

Monitoring Recommendations

Enable Liferay audit logging for the publication and comments modules and forward events to a centralized SIEM for anomaly analysis.
Baseline normal comment volume and author distribution per publication, and alert on statistical outliers.
Monitor authentication and session logs for concurrent activity that suggests session riding, such as comment writes without preceding UI navigation.

How to Mitigate CVE-2025-62245

Immediate Actions Required

Upgrade Liferay Portal to a version beyond 7.4.3.112 and Liferay DXP to a release beyond the affected 2023.Q4.5, 2023.Q3.10, and 7.4 update 92 levels.
Inventory all internal and external Liferay instances and validate their patch level against the vendor advisory.
Instruct privileged users to log out of Liferay when not actively using the portal to shrink the CSRF exposure window.

Patch Information

Liferay has published guidance and fixed releases through the Liferay CVE-2025-62245 Advisory. Administrators should apply the fix packs or upgrade to a Quarterly Release that supersedes the affected versions listed in that advisory.

Workarounds

Enforce strict SameSite=Lax or SameSite=Strict attributes on Liferay session cookies to block cross-site cookie transmission.
Restrict access to the Liferay administrative and publication interfaces to trusted networks or VPN users until patches are applied.
Configure an upstream WAF or reverse proxy to block requests to publication comment endpoints when the Origin or Referer header does not match the portal's own hostname.

bash

# Example NGINX reverse proxy snippet enforcing same-origin on Liferay comment endpoints
location ~* /o/.*publications.*comment {
    if ($http_origin !~* ^https://portal\.example\.com$) {
        return 403;
    }
    proxy_pass http://liferay_upstream;
}
