Overview
CVE-2025-65672 details an Insecure Direct Object Reference (IDOR) vulnerability found in classroomio version 0.1.13. This vulnerability allows unauthorized users to potentially access and modify course settings, including sharing and invitation configurations, without proper authorization. This could lead to significant security risks, potentially impacting data privacy and integrity within the classroomio platform.
Technical Details
The IDOR vulnerability exists in the handling of course identification during share and invite operations within classroomio 0.1.13. An attacker could potentially manipulate the course ID parameter in a request to access settings of a course they are not authorized to manage. By altering the course ID, a malicious actor could gain unauthorized control over course sharing and invitation functionalities.
Specifically, the application fails to properly validate that the user initiating the request has the necessary permissions to interact with the specified course ID. This lack of validation is the core of the IDOR issue.
CVSS Analysis
Due to the provided information indicating an “N/A” severity and CVSS score, a formal CVSS analysis cannot be provided. However, even without a numerical score, it’s crucial to understand the potential impact. While a CVSS score provides a standardized measure of severity, the potential for unauthorized access to course settings suggests a significant security risk.
Possible Impact
The exploitation of CVE-2025-65672 can lead to the following potential impacts:
- Unauthorized Access: Attackers can gain access to course settings that they should not have permission to view or modify.
- Data Manipulation: Modification of course settings could lead to unintended or malicious changes to the course environment.
- Privacy Breach: Sharing and invitation controls can be manipulated to expose student data or invite malicious actors into the course.
- Denial of Service: Malicious changes to course configurations could disrupt the functionality of the classroomio platform.
Mitigation and Patch Steps
To mitigate CVE-2025-65672, the following steps are recommended:
- Upgrade: Upgrade to a patched version of classroomio that addresses this vulnerability. Check classroomio.com for the latest releases and security advisories.
- Input Validation: Implement robust input validation and sanitization for all parameters related to course IDs.
- Authorization Checks: Enforce strict authorization checks to ensure that only authorized users can access and modify course settings. Verify the user’s permissions before allowing any action on a specific course.
- Principle of Least Privilege: Grant users only the minimum necessary privileges required to perform their tasks.
