CVE-2025-43808 is a security vulnerability affecting multiple versions of the Liferay Portal, specifically versions 7.3.0 through 7.4.3.112 and various Liferay DXP releases from 2023.Q3.1 through 2023.Q4.8. The vulnerability arises from incorrect permission assignment (CWE-732) in the Commerce component of Liferay Portal. Virtual products uploaded to the Documents and Media repository are saved with guest view permissions by default. This misconfiguration allows remote attackers to bypass intended access controls and download virtual products without authorization simply by using a crafted URL. The vulnerability requires no authentication or user interaction and can be exploited remotely over the network. The CVSS 4.0 base score is 6.9 (medium severity), reflecting the ease of exploitation (network attack vector, low attack complexity) and the impact limited primarily to confidentiality (unauthorized access to virtual products). There is no indication of known exploits in the wild or available patches at the time of publication. This vulnerability could lead to unauthorized distribution of digital goods, resulting in financial losses and intellectual property exposure for affected organizations using Liferay Portal's Commerce features.

For European organizations using Liferay Portal for e-commerce or digital content delivery, this vulnerability poses a significant risk to the confidentiality and commercial integrity of virtual products. Unauthorized access and free downloads can lead to revenue loss, damage to brand reputation, and potential legal issues related to intellectual property rights. Organizations in sectors such as retail, digital media, education, and software distribution that rely on Liferay Commerce to manage and sell virtual goods are particularly vulnerable. The exposure of sensitive digital assets could also undermine customer trust and contractual obligations. Additionally, if exploited at scale, this vulnerability could disrupt business operations and necessitate costly incident response and remediation efforts.

To mitigate this vulnerability, European organizations should immediately audit their Liferay Portal Commerce configurations to verify and correct permission settings on virtual products stored in Documents and Media. Specifically, ensure that guest or anonymous user permissions are not granted to sensitive digital assets. Until an official patch is released, organizations should consider restricting access to the Documents and Media repository via network-level controls such as firewalls or VPNs, limiting access to trusted users only. Implementing strict access control policies and regularly reviewing permission assignments can prevent unauthorized exposure. Monitoring web server logs for unusual access patterns to virtual product URLs may help detect exploitation attempts. Organizations should also stay updated with Liferay security advisories and apply patches promptly once available. As a longer-term measure, consider implementing digital rights management (DRM) or watermarking solutions to protect virtual products from unauthorized distribution.
