CVE-2025-64251 identifies a missing authorization vulnerability in azzaroco Ultimate Learning Pro, a learning management system widely used for educational and corporate training purposes. The flaw arises from incorrectly configured access control security levels, which fail to properly enforce authorization checks on certain functions or resources. This misconfiguration allows an attacker to perform actions or access data that should be restricted, potentially leading to unauthorized data disclosure, modification, or administrative actions. The affected versions include all releases up to and including 3.9.3. The vulnerability does not require prior authentication or user interaction, increasing its risk profile. Although no public exploits have been reported, the nature of the vulnerability suggests that exploitation could be straightforward for an attacker with network access to the application. The absence of a CVSS score indicates that the vulnerability is newly disclosed and pending further evaluation. The vulnerability primarily impacts the confidentiality and integrity of data managed by the LMS, with possible secondary effects on availability if unauthorized changes disrupt service. The vendor has not yet published patches or mitigations, so organizations must rely on compensating controls until updates are available.

For European organizations, especially educational institutions and enterprises relying on azzaroco Ultimate Learning Pro for training and knowledge management, this vulnerability poses a significant risk. Unauthorized access could lead to exposure of sensitive personal data of students and employees, intellectual property theft, or manipulation of learning content and records. This could result in regulatory non-compliance with GDPR and other data protection laws, financial penalties, and reputational damage. The potential for privilege escalation or administrative control takeover could further exacerbate the impact by enabling attackers to pivot within the network or disrupt critical learning services. Given the increasing reliance on digital learning platforms across Europe, the scope of affected systems could be broad, affecting both public and private sectors. The lack of known exploits currently reduces immediate risk but does not diminish the urgency for mitigation due to the ease of exploitation and the critical nature of the data involved.

European organizations should immediately conduct thorough access control audits on their Ultimate Learning Pro deployments to identify and remediate any misconfigurations. Until official patches are released, implement strict network segmentation to limit access to the LMS to trusted users and systems only. Deploy web application firewalls (WAFs) with custom rules designed to detect and block unauthorized access attempts targeting known vulnerable endpoints. Enable detailed logging and continuous monitoring to detect anomalous activities indicative of exploitation attempts. Educate administrators and users about the vulnerability and enforce the principle of least privilege for all LMS accounts. Coordinate with azzaroco for timely updates and apply patches as soon as they become available. Consider temporary disabling or restricting high-risk functionalities if feasible. Additionally, review incident response plans to prepare for potential exploitation scenarios.
