CVE-2025-47573 is a critical SQL Injection vulnerability (CWE-89) identified in the mojoomla School Management software, affecting versions up to 92.0.0. This vulnerability allows an unauthenticated remote attacker to perform Blind SQL Injection attacks against the backend database by exploiting improper neutralization of special elements in SQL commands. The vulnerability is remotely exploitable over the network without requiring any user interaction or authentication, as indicated by the CVSS vector (AV:N/AC:L/PR:N/UI:N). The scope is changed (S:C), meaning the vulnerability can affect resources beyond the initially vulnerable component, potentially impacting the confidentiality of the entire database. The CVSS score of 9.3 reflects a critical severity primarily due to the high impact on confidentiality (C:H), with no impact on integrity (I:N) and low impact on availability (A:L). Blind SQL Injection enables attackers to infer sensitive data by sending crafted queries and analyzing responses or timing differences, even without direct error messages. Given the nature of the software—school management systems—this vulnerability could expose sensitive personal data of students, staff, and administrative records, including grades, attendance, and possibly financial information. The lack of available patches at the time of publication increases the urgency for organizations to implement mitigations. No known exploits in the wild have been reported yet, but the ease of exploitation and critical impact make this a high-risk vulnerability that requires immediate attention.

For European organizations, especially educational institutions using mojoomla School Management software, this vulnerability poses a significant risk to the confidentiality of sensitive data. Exposure of personal identifiable information (PII) of students and staff could lead to privacy violations under GDPR, resulting in legal and financial penalties. Additionally, the compromise of school administrative data could disrupt educational operations and damage institutional reputation. Since the vulnerability allows remote exploitation without authentication, attackers could leverage this flaw to conduct large-scale data exfiltration or reconnaissance campaigns. The potential for lateral movement within networks exists if attackers gain access to backend databases, possibly affecting other connected systems. The low impact on availability suggests that denial-of-service is less likely, but data confidentiality breaches alone are critical in the education sector. The absence of known exploits currently provides a window for proactive defense, but the critical CVSS score indicates that exploitation could have severe consequences if weaponized.

1. Immediate mitigation should focus on network-level controls: restrict external access to the School Management system database and application interfaces using firewalls and network segmentation, allowing only trusted internal IP ranges. 2. Implement Web Application Firewalls (WAFs) with custom rules to detect and block SQL Injection payloads targeting mojoomla School Management endpoints. 3. Conduct thorough input validation and sanitization on all user-supplied data fields within the application, employing parameterized queries or prepared statements to prevent injection. 4. Monitor application logs and database query patterns for anomalous behavior indicative of Blind SQL Injection attempts, such as unusual query timing or error patterns. 5. Engage with mojoomla vendor or community channels to obtain or request patches or updates addressing this vulnerability as soon as they become available. 6. Perform regular security assessments and penetration testing focused on injection flaws to identify and remediate similar issues proactively. 7. Educate IT and security staff in affected organizations about this vulnerability and encourage rapid incident response readiness. 8. Where feasible, consider temporary replacement or isolation of the vulnerable system until a patch is applied to minimize exposure.
