Overview
CVE-2025-65669 describes a critical vulnerability discovered in classroomio version 0.1.13. This flaw allows student accounts to delete courses directly from the “Explore” page. This action should be restricted to administrator accounts only. The vulnerability stems from a lack of proper authorization and authentication checks before executing the deletion function.
Technical Details
The vulnerability exists because the application fails to verify the user’s role or permissions before allowing them to delete a course. A student user can manipulate the application (e.g., by intercepting and modifying HTTP requests) to trigger the deletion functionality normally reserved for administrators. There are no apparent authorization or authentication checks on the server-side endpoint responsible for course deletion.
CVSS Analysis
Currently, a CVSS score for CVE-2025-65669 is unavailable. However, based on the nature of the vulnerability, its potential impact, and the lack of required privileges for exploitation, it is likely to be categorized as a High severity issue once a CVSS score is calculated. Factors contributing to the potential high severity include data integrity concerns (course data loss) and potential disruptions to the learning environment.
Possible Impact
The impact of this vulnerability can be significant. A malicious or misguided student could:
- Delete essential course materials, causing disruption to learning.
- Sabotage the learning environment for other students.
- Potentially cause data loss if course deletions are not properly logged or backed up.
- Create general chaos and distrust within the classroom platform.
Mitigation or Patch Steps
To address this vulnerability, the following steps are recommended:
- Upgrade Classroomio: Upgrade to a patched version of Classroomio that addresses this vulnerability. Check classroomio.com for announcements and updates.
- Implement Role-Based Access Control (RBAC): Implement a robust RBAC system that properly restricts course deletion functionality to administrator accounts only.
- Server-Side Validation: Ensure that all deletion requests are thoroughly validated on the server-side to verify the user’s permissions.
- Input Sanitization: Sanitize all user inputs to prevent potential injection attacks.
- Regular Security Audits: Conduct regular security audits to identify and address potential vulnerabilities.
