CVE-2025-62250: Liferay DXP Auth Bypass Vulnerability

CVE-2025-62250 Overview

CVE-2025-62250 is an improper authentication vulnerability affecting Liferay Portal and Liferay Digital Experience Platform (DXP). The flaw allows remote attackers to send malicious data over unauthenticated cluster messages, which the platform accepts as trusted input. The issue is classified under CWE-346: Origin Validation Error and impacts Liferay Portal versions 7.4.0 through 7.4.3.132, as well as Liferay DXP 2023.Q4.0, 2023.Q3.1 through 2023.Q3.4, 7.4 GA through update 92, and 7.3 GA through update 35. Older, unsupported versions are also affected.

Critical Impact
Unauthenticated remote attackers can inject data into Liferay cluster communications and have it processed as trusted, undermining integrity and confidentiality boundaries in clustered deployments.

Affected Products

Liferay Portal 7.4.0 through 7.4.3.132 (and older unsupported versions)
Liferay DXP 2023.Q4.0, 2023.Q3.1 through 2023.Q3.4
Liferay DXP 7.4 GA through update 92, and 7.3 GA through update 35

Technical Details for CVE-2025-62250

Vulnerability Analysis

Liferay Portal and DXP support clustered deployments where multiple nodes exchange state and cache invalidation events through cluster messages. The vulnerability arises because the cluster messaging channel does not enforce authentication on inbound messages. Any actor able to reach the cluster communication endpoint can submit crafted messages that the receiving node processes as if they originated from a trusted peer.

Because cluster messages influence internal application state, an attacker leveraging this flaw can manipulate data flows within the portal without holding valid user credentials. The vulnerability requires network access to the cluster transport, low attack complexity, and no user interaction.

Root Cause

The root cause is missing origin validation on cluster messages. Liferay nodes do not verify that the sender of a cluster message is an authenticated peer before treating the payload as trusted. This weakness maps directly to [CWE-346], where the receiving component relies on the source of the data being legitimate without cryptographic or credential-based verification.

Attack Vector

An attacker with network reach to the Liferay cluster transport port can send forged cluster messages to any exposed node. The platform deserializes and acts on this data as if it came from a legitimate cluster peer. Deployments that expose cluster ports to untrusted networks — including flat internal networks without segmentation — are directly reachable.

No verified public proof-of-concept code is available for this issue. Refer to the Liferay Security Advisory CVE-2025-62250 for vendor-provided technical detail.

Detection Methods for CVE-2025-62250

Indicators of Compromise

Unexpected connections to Liferay cluster transport ports from hosts outside the defined cluster node list.
Anomalous cluster message volume, message sizes, or event types recorded in Liferay logs.
Portal state changes (cache invalidations, configuration updates) that do not correspond to any authenticated administrator action.

Detection Strategies

Inventory Liferay Portal and DXP instances and correlate their versions against the affected version ranges published in the Liferay advisory.
Monitor network flows to Liferay cluster ports (JGroups/UDP multicast or TCP unicast, depending on configuration) for source addresses outside the approved cluster membership.
Enable and review Liferay application logs for cluster message handlers processing unexpected message types or payload structures.

Monitoring Recommendations

Alert on any inbound traffic to Liferay cluster transport ports originating from non-cluster segments.
Track integrity of cache and configuration state across cluster nodes to detect divergence introduced by injected messages.
Baseline normal cluster message rates and payload sizes, then alert on deviations that may indicate injection attempts.

How to Mitigate CVE-2025-62250

Immediate Actions Required

Apply the fixed versions of Liferay Portal and Liferay DXP as published in the Liferay Security Advisory CVE-2025-62250.
Restrict network access to Liferay cluster transport ports so that only authorized cluster nodes can communicate on those interfaces.
Audit exposure of cluster ports across all environments, including development and staging, where clustering may be enabled.

Patch Information

Liferay has released updates addressing CVE-2025-62250 for supported branches of Liferay Portal 7.4 and Liferay DXP 2023.Q4, 2023.Q3, 7.4, and 7.3. Consult the vendor advisory for the specific fixed update or quarterly release that resolves this issue in each affected branch. Unsupported versions require migration to a supported, patched release.

Workarounds

Bind Liferay cluster communication to a dedicated, isolated network interface reachable only by cluster peers.
Enforce firewall rules or security groups that allow cluster traffic exclusively between known cluster node IP addresses.
Disable clustering on nodes that do not require it until patched versions can be deployed.

bash

# Example: restrict Liferay cluster port access with iptables (adjust port and peer IPs)
iptables -A INPUT -p tcp --dport 7800 -s 10.0.0.11 -j ACCEPT
iptables -A INPUT -p tcp --dport 7800 -s 10.0.0.12 -j ACCEPT
iptables -A INPUT -p tcp --dport 7800 -j DROP
