CVE-2025-15655 SQL Injection in Mojoomla School Management

Technical summary

CVE-2025-15655 is a SQL injection vulnerability (CWE-89) in Mojoomla School Management stemming from improper neutralization of special characters in SQL queries. The vulnerability requires high-privilege authentication, but does not require user interaction. The attack vector is network-accessible, and exploitation can affect confidentiality across system boundaries (per CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:N/A:L). The flaw enables attackers to craft malicious SQL statements that bypass intended query logic, potentially exfiltrating student records, staff data, or grade information.

Business impact

School administrators and IT teams using Mojoomla School Management face risk of unauthorized data access and integrity issues. Student personally identifiable information (PII), attendance records, grades, and administrative data could be exposed or corrupted. Such breaches trigger regulatory compliance obligations (FERPA in the US, GDPR in the EU) and reputational harm. Service availability may also be impacted if an attacker performs resource-exhaustive queries. Organizations relying on this platform should prioritize assessment and remediation to protect sensitive educational records.

Affected systems

Mojoomla School Management versions through 93.2.0 are affected. Verify your installed version in the platform's administration dashboard or by checking deployment documentation. Customers using earlier releases remain in scope; consult the vendor advisory for the complete version timeline and any versions that may have been patched.

Exploitability

Exploitation requires an authenticated user with high-privilege administrative access. No public exploit code has been cataloged in the Known Exploited Vulnerabilities (KEV) catalog as of the advisory publication. However, the low attack complexity (AC:L) and network accessibility mean that once authentication is achieved—through credential compromise, insider threat, or social engineering—exploitation is straightforward and requires no special tools beyond a database query interface.

Remediation

Update Mojoomla School Management to a version newer than 93.2.0 that includes fixes for SQL injection vulnerabilities. Verify patch availability by consulting the official Mojoomla vendor advisory and installation documentation. In parallel, enforce principle-of-least-privilege for administrator accounts, conduct database access reviews, and implement network segmentation to limit administrative interface exposure.

Patch guidance

Contact Mojoomla support or check the vendor's official advisory to confirm the availability and version number of patched releases. Apply updates in a controlled environment first, test thoroughly with your school's workflows (enrollment, grading, attendance), and then deploy to production. Consider scheduling updates during maintenance windows to minimize disruption to staff and students.

Detection guidance

Monitor database query logs for unusual SQL patterns, UNION statements, or comment sequences (-- or /*) originating from the School Management application or administrative accounts. Implement database activity monitoring (DAM) tools to detect anomalous SELECT, INSERT, UPDATE, or DELETE operations. Review application authentication logs for unexpected login attempts to high-privilege accounts, and correlate those with periods of suspicious database activity. Network intrusion detection systems (IDS) may flag SQL keywords in HTTP requests to the administration interface.

Why prioritize this

Despite KEV non-listing and the requirement for high-privilege authentication, this vulnerability warrants prompt attention because it directly threatens sensitive educational records subject to strict privacy regulations. The HIGH severity rating reflects significant confidentiality impact and cross-system scope. Schools often operate under budget and staffing constraints, making targeted social engineering or insider threats realistic attack vectors against administrator credentials.

Risk score, explained

The CVSS 3.1 score of 7.6 (HIGH) reflects high confidentiality impact (C:H), low integrity impact (I:N), and low availability impact (A:L). The requirement for high-privilege authentication (PR:H) prevents remote unauthenticated exploitation but does not eliminate risk. Network accessibility (AV:N) and low attack complexity (AC:L) mean that privilege-escalation chains or compromised admin accounts could enable swift exploitation. The changed scope (S:C) indicates the vulnerability can affect resources beyond the vulnerable component.
