Executive Summary

CVE-2025-43801 is a denial-of-service (DoS) vulnerability in the XML-RPC component of Liferay Portal and Liferay DXP. It occurs because the software does not properly check input used as a loop condition. Remote attackers can exploit this by sending specially crafted XML-RPC requests that cause excessive looping, which exhausts system resources and disrupts service availability. [1]

Impact Analysis

This vulnerability can impact you by allowing remote attackers to cause a denial-of-service (DoS) attack on your Liferay Portal or DXP system. The attack leads to resource exhaustion due to excessive looping triggered by crafted XML-RPC requests, resulting in service disruption and unavailability. [1]

Mitigation Strategies

To mitigate this vulnerability, immediately update your Liferay Portal or Liferay DXP installations to a fixed version. The fixed versions are Liferay Portal 7.4.3.112, Liferay DXP 2024.Q1.1, Liferay DXP 2023.Q4.0, Liferay DXP 2023.Q3.5, and Liferay DXP 7.3 U36. Applying these updates will address the unchecked input vulnerability in the XML-RPC component and prevent denial-of-service attacks. [1]
