CVE-2025-52833 is a critical SQL Injection vulnerability (CWE-89) identified in the designthemes LMS (Learning Management System) product. This vulnerability arises from improper neutralization of special elements used in SQL commands, allowing an attacker to inject malicious SQL code into the backend database queries. The affected versions include all versions up to 9.1, with no specific lower bound version provided. The vulnerability has a CVSS 3.1 base score of 9.3, indicating a critical severity level. The CVSS vector (AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:N/A:L) reveals that the attack can be performed remotely over the network without any authentication or user interaction, with low attack complexity. The scope is changed, meaning the vulnerability affects components beyond the initially vulnerable component. The impact on confidentiality is high, allowing attackers to read sensitive data from the database, while integrity impact is none and availability impact is low. Although no known exploits are currently reported in the wild, the nature of SQL Injection vulnerabilities makes this a high-risk issue, as attackers can potentially extract sensitive information such as user credentials, personal data, or proprietary content stored in the LMS database. The vulnerability could also be leveraged for further attacks like privilege escalation or lateral movement within the network if combined with other vulnerabilities. The lack of available patches at the time of publication increases the urgency for organizations to implement compensating controls and monitor for suspicious activity.

For European organizations using designthemes LMS, this vulnerability poses a significant risk to the confidentiality of sensitive educational and personal data. LMS platforms typically store user information, course content, grades, and potentially payment or identity verification details. Exploitation could lead to unauthorized data disclosure, violating GDPR and other data protection regulations, resulting in legal penalties and reputational damage. The critical severity and ease of exploitation (no authentication or user interaction required) mean that attackers can remotely compromise systems with minimal effort. This could disrupt educational services, erode trust among students and staff, and expose organizations to targeted attacks or espionage. Additionally, the changed scope indicates that the impact could extend beyond the LMS itself, potentially affecting integrated systems or databases. European institutions, especially universities and training providers that rely heavily on LMS platforms, are at risk of data breaches and operational disruption if this vulnerability is exploited.

Given the absence of an official patch at the time of disclosure, European organizations should take immediate, specific actions to mitigate risk: 1) Implement Web Application Firewalls (WAFs) with custom rules to detect and block SQL Injection patterns targeting the LMS. 2) Conduct thorough input validation and sanitization on all user inputs interacting with the LMS, particularly those that interface with database queries. 3) Restrict database user permissions to the minimum necessary, avoiding use of high-privilege accounts for LMS database access to limit potential data exposure. 4) Monitor LMS logs and network traffic for unusual query patterns or spikes in database errors that may indicate attempted exploitation. 5) Isolate the LMS environment within segmented network zones to reduce lateral movement risk if compromised. 6) Prepare for rapid deployment of patches once available by maintaining an up-to-date inventory of affected LMS instances. 7) Educate LMS administrators and security teams about the vulnerability and encourage prompt incident response readiness. These targeted measures go beyond generic advice by focusing on compensating controls and proactive detection tailored to the nature of this SQL Injection vulnerability.
