CVE-2025-62250 is a vulnerability identified in Liferay Portal versions 7.4.0 through 7.4.3.132 and multiple Liferay DXP releases, stemming from CWE-346: Origin Validation Error. The core issue is improper authentication in the handling of cluster messages, where the portal fails to correctly validate the origin of incoming messages within a clustered environment. This flaw allows remote attackers to send malicious, unauthenticated cluster messages that the system mistakenly treats as trusted. As a result, attackers can inject malicious data or commands into the cluster communication channel, potentially leading to unauthorized actions such as data manipulation or disruption of cluster operations. The vulnerability requires no authentication or user interaction and can be exploited remotely over the network, increasing its risk profile. The CVSS 4.0 vector (AV:N/AC:L/AT:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N) indicates network attack vector, low attack complexity, no privileges or user interaction required, and limited impact on confidentiality and integrity but no impact on availability. No patches were linked at the time of reporting, and no known exploits have been observed in the wild. The vulnerability affects both supported and older unsupported versions, emphasizing the need for organizations to verify their Liferay versions and apply mitigations accordingly.

For European organizations, the impact of CVE-2025-62250 can be significant, particularly for those relying on Liferay Portal or DXP in clustered deployments. The improper origin validation allows attackers to bypass authentication controls within cluster communications, potentially leading to unauthorized data injection or manipulation. This can compromise the integrity of data shared across cluster nodes and may disrupt normal portal operations. Confidentiality impact is limited but not negligible, as malicious messages could influence data processing or expose internal cluster state. Availability impact is minimal according to CVSS, but operational disruptions could occur if attackers exploit the vulnerability to destabilize cluster synchronization. Organizations in sectors such as government, finance, healthcare, and large enterprises using Liferay for intranet portals or customer-facing services are at higher risk. The vulnerability's remote exploitability without authentication increases the attack surface, especially if cluster communication is exposed or insufficiently protected. Failure to address this vulnerability could lead to unauthorized access to sensitive internal communications and potential lateral movement within the network.

1. Monitor Liferay's official channels for patches addressing CVE-2025-62250 and apply them promptly once released. 2. Restrict cluster communication to trusted internal networks only; implement network segmentation and firewall rules to block unauthorized access to cluster ports. 3. Employ network-level filtering or intrusion detection systems to detect and block anomalous or unauthenticated cluster messages. 4. Review and harden cluster configuration settings to enforce strict origin validation and authentication mechanisms if configurable. 5. Conduct regular audits of Liferay cluster logs to identify suspicious or unexpected cluster message activity. 6. For organizations unable to immediately patch, consider temporarily disabling clustering features if feasible or isolating cluster nodes to minimize exposure. 7. Educate system administrators about the risks of unauthenticated cluster messages and the importance of secure network architecture around Liferay deployments. 8. Implement robust monitoring and incident response plans focused on detecting exploitation attempts targeting cluster communication.
