CVE-2025-59467 identifies a Cross-Site Scripting (XSS) vulnerability in the UCRM Argentina AFIP invoices Plugin, versions 1.2.0 and earlier, developed by Ubiquiti Inc. This plugin integrates with Ubiquiti's UCRM platform to facilitate invoicing compliant with Argentina's Federal Administration of Public Revenues (AFIP). The vulnerability arises from improper sanitization of user-supplied input, allowing an attacker to inject malicious scripts. If an administrator visits a specially crafted malicious page, the injected script can execute in the context of the administrator's browser session. This can lead to privilege escalation, enabling the attacker to perform unauthorized actions within the UCRM platform, potentially compromising sensitive invoicing data and administrative controls. The plugin is disabled by default, which limits exposure, but if enabled, the risk is significant. The CVSS v3.1 score of 7.5 reflects a high severity, with network attack vector, high attack complexity, no privileges required, but user interaction necessary. The vulnerability affects confidentiality, integrity, and availability of the system. No known exploits are currently in the wild, but the risk remains if the plugin is enabled and unpatched. The recommended mitigation is to update to version 1.3.0 or later, where input validation and sanitization have been improved to prevent XSS attacks.

For European organizations, the impact of this vulnerability depends largely on their use of Ubiquiti's UCRM platform with the Argentina AFIP invoices Plugin enabled. Organizations with subsidiaries, partners, or clients in Argentina that require compliance with AFIP invoicing standards are most at risk. Successful exploitation could lead to unauthorized administrative access, data leakage of sensitive financial and client information, manipulation of invoicing data, and potential disruption of billing operations. This could result in financial loss, regulatory non-compliance, reputational damage, and operational downtime. Given the plugin is disabled by default, many organizations may not be exposed; however, those that have enabled it without patching remain vulnerable. The requirement for user interaction (administrator visiting a malicious page) means phishing or social engineering could be vectors for exploitation. European companies with remote or distributed administrative teams may face increased risk. The vulnerability's high severity and potential for privilege escalation make it a critical concern for affected deployments.

1. Immediately update the UCRM Argentina AFIP invoices Plugin to version 1.3.0 or later, which contains the necessary patches to fix the XSS vulnerability. 2. If the plugin is not required, ensure it remains disabled to reduce attack surface. 3. Implement strict web filtering and email security controls to reduce the risk of administrators receiving malicious links or pages. 4. Educate administrators on the risks of phishing and social engineering attacks that could lead to visiting malicious pages. 5. Monitor administrative access logs for unusual activity that could indicate exploitation attempts. 6. Employ Content Security Policy (CSP) headers on the UCRM platform to mitigate the impact of potential XSS attacks. 7. Regularly audit and sanitize all user inputs and outputs within the UCRM environment, especially for plugins handling external data. 8. Coordinate with Ubiquiti support for any additional security advisories or patches related to this plugin. 9. Consider network segmentation to isolate UCRM administrative interfaces from general user networks to limit exposure. 10. Maintain up-to-date backups of invoicing and administrative data to enable recovery in case of compromise.
