Security readout for executives and security teams
Plain-English summary
CVE-2020-37147 is a SQL injection issue in ATutor 2.2.4. An authenticated attacker can manipulate the user deletion page’s id parameter and potentially read or alter database data. This matters most where ATutor stores learner, staff, or administrative information.
Executive priority
Prioritize remediation for any live ATutor 2.2.4 system, especially if internet-facing or storing sensitive learning records. If ATutor is not used, close as not applicable after inventory confirmation.
Technical view
ATutor 2.2.4 is affected by CWE-89 SQL injection in admin_delete.php via the id parameter. The supplied CVSS 3.1 score is 7.1, with network access, low attack complexity, low privileges, no user interaction, high confidentiality impact, and low integrity impact.
Likely exposure
Exposure is limited to organizations running ATutor 2.2.4, especially where authenticated users can reach the affected administrative deletion functionality. Internet-facing ATutor instances increase business risk, but the source bundle does not confirm broad deployment or specific configurations.
Exploitation context
A public ExploitDB reference exists, so technical details are publicly available. The source bundle does not show CISA KEV listing or confirmed active exploitation. Treat as a credible risk for any remaining ATutor 2.2.4 deployment.
Researcher notes
Evidence supports SQL injection in the id parameter of the admin user deletion page. Public exploit reference is cited, but active exploitation is not established. The bundle does not name a patch, so remediation should be tied to current vendor or maintainer guidance.
Mitigation direction
- Identify any ATutor 2.2.4 systems in production, staging, or archives.
- Check ATutor or maintainer guidance for fixed versions or official remediation.
- Restrict access to ATutor administrative functions to trusted users only.
- Limit network access to ATutor administration where business operations allow.
- Back up and review database integrity if exposure is confirmed.
Validation and detection
- Confirm the installed ATutor version is not 2.2.4.
- Review whether admin_delete.php is present and reachable by authenticated users.
- Use safe vulnerability scanning or code review to verify id parameter handling.
- Review application and database logs for unusual authenticated deletion-page activity.
- Document compensating controls if no vendor fix is available.

Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')
Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
