CVE-2025-11052 is a SQL Injection vulnerability identified in the kidaze CourseSelectionSystem, specifically affecting version 1.0 and the 5.php component. The vulnerability resides in an unknown function within the file /Profilers/PriProfile/COUNT3s5.php, where manipulation of the 'csslc' argument allows an attacker to inject malicious SQL code. This flaw can be exploited remotely without requiring any authentication or user interaction, making it particularly dangerous. The injection can lead to unauthorized access to the backend database, potentially allowing attackers to read, modify, or delete sensitive data stored within the system. The vulnerability has a CVSS 4.0 base score of 6.9, categorized as medium severity, reflecting its network attack vector, low attack complexity, and no privileges or user interaction needed. The impact on confidentiality, integrity, and availability is considered low individually but combined can lead to significant data compromise. Although no public exploits are currently known to be actively exploited in the wild, the availability of a public exploit increases the risk of future attacks. The CourseSelectionSystem is likely used by educational institutions to manage course registrations, making the data involved sensitive and critical for operational continuity.

For European organizations, particularly educational institutions and universities using the kidaze CourseSelectionSystem, this vulnerability poses a risk of unauthorized data exposure and manipulation. Attackers exploiting this flaw could access student records, course enrollment data, and potentially administrative credentials, leading to privacy violations under GDPR and operational disruptions. The integrity of course selection data could be compromised, affecting academic scheduling and resource allocation. Additionally, exploitation could serve as a foothold for further network intrusion or lateral movement within institutional IT environments. The remote and unauthenticated nature of the vulnerability increases the likelihood of exploitation attempts, especially in environments where patching is delayed or where the system is exposed to the internet without adequate network segmentation or web application firewalls.

Immediate mitigation should include applying any available patches or updates from the vendor; however, no patch links are currently provided, so organizations should contact kidaze for remediation guidance. In the interim, organizations should implement strict input validation and parameterized queries to prevent SQL injection. Deploying Web Application Firewalls (WAFs) configured to detect and block SQL injection patterns targeting the 'csslc' parameter can reduce risk. Network segmentation should be enforced to limit external access to the CourseSelectionSystem, and monitoring for unusual database queries or access patterns should be enhanced. Regular security assessments and code reviews of the affected components are recommended to identify and remediate similar vulnerabilities. Additionally, organizations should ensure that database accounts used by the application have the least privileges necessary to limit the impact of any successful injection.
