CVE-2024-38002: Critical Vulnerability in Liferay Digital Experience Platform

The workflow component in Liferay Portal versions 7.3.2 through 7.4.3.111 and Liferay DXP versions 2023.Q4.0 through 2023.Q4.5, as well as 2023.Q3.1 through 2023.Q3.8, contains a critical vulnerability. This vulnerability allows remote authenticated users to modify workflow definitions and execute arbitrary code via the headless API due to improper permission checks before updating a workflow definition. With a CVSS score of 9, this vulnerability is classified as critical.

Risk to organizations includes potential unauthorized access and manipulation of workflow processes, leading to severe operational impacts. Attackers may leverage this vulnerability to execute arbitrary code, which can compromise the integrity and availability of the affected systems. Given its critical nature, organizations using the affected versions should prioritize patching immediately.

As of now, there is no public exploit confirmed for this vulnerability, and it has not been listed in the Known Exploited Vulnerabilities (KEV) catalog. However, organizations are advised to remain vigilant as the risk remains high due to the nature of the vulnerability. Continuous monitoring and implementing best practices for security can help mitigate potential threats.

Organizations using Liferay products should assess their environments to identify vulnerable versions and take prompt action to remediate this vulnerability.

Vulnerability Details

The workflow component in Liferay Portal versions 7.3.2 through 7.4.3.111, and Liferay DXP versions 2023.Q4.0 through 2023.Q4.5, 2023.Q3.1 through 2023.Q3.8, 7.4 GA through update 92, and 7.3 GA through update 36 does not properly check user permissions before updating a workflow definition, which allows remote authenticated users to modify workflow definitions and execute arbitrary code (RCE) via the headless API.

The CVSS score of this vulnerability is 9, indicating a critical severity level. This evaluation is supported by the high potential for confidentiality, integrity, and availability impacts, as indicated in the CVSS vector, which specifies a low attack complexity and required low privileges. The vulnerability falls under CWE-862 (Incorrect Permission Assignment for Critical Resource) and CWE-863 (Incorrect Authorization).

Technical Analysis

The root cause of this vulnerability lies in the failure to validate user permissions correctly before allowing modifications to workflow definitions. This oversight enables unauthorized users to exploit the headless API without adequate safeguards. The attack vector is network-based, and the complexity is low, meaning that the vulnerability can be exploited remotely without extensive resources.

The attack requires low privileges, and user interaction may be needed, depending on the scenario. The impacts of exploitation are severe: the confidentiality, integrity, and availability of the system can be compromised, allowing attackers to manipulate workflows and potentially affect critical business operations.

Risk & Impact Analysis

Organizations utilizing Liferay's Digital Experience Platform face significant risks due to this vulnerability. The potential for unauthorized modifications to workflow definitions can lead to critical disruptions in business processes and data integrity. The blast radius of this vulnerability is extensive, as any remote authenticated user could exploit it to execute arbitrary code and gain unauthorized access to sensitive data.

Given the CVSS score of 9, organizations should prioritize addressing this vulnerability in their patch management cycle. The urgency is further reinforced by the high exploitation potential, even without confirmed public exploits available at this time.

Exploitation Status

Affected Versions

The affected versions include Liferay Portal from 7.3.2 to 7.4.3.111 and Liferay DXP from 2023.Q4.0 to 2023.Q4.5, along with 2023.Q3.1 to 2023.Q3.8. Organizations should note that all versions prior to the vendor patch are vulnerable.

Mitigation & Remediation

Organizations should immediately apply the latest security patches provided by Liferay to mitigate this vulnerability. Upgrading to the patched versions is crucial to prevent unauthorized access and potential exploitation. If patching is not feasible, organizations should implement strict access controls and monitor for unusual activities in order to minimize the risk.

For comprehensive security, organizations can consider employing penetration testing to evaluate the effectiveness of their security measures against this vulnerability.

Detection Guidance

Organizations should monitor system logs for any unauthorized changes to workflow definitions, as well as anomalous API access patterns that indicate potential exploitation attempts. Behavioral anomalies in user activities must be flagged for further investigation.
