DescriptionCVE.org

A security vulnerability has been detected in tittuvarghese CollegeManagementSystem 3e476335cfbfb9a049e09f474c7ec885f69a9df3/a38852979f7e27ae67b610dce5979500ef8ebe01. The impacted element is an unknown function of the file dashboard_page/forms/upload_student_data.php of the component Student Data Upload Endpoint. Such manipulation of the argument Student-Data-CSV leads to unrestricted upload. It is possible to launch the attack remotely. The exploit has been disclosed publicly and may be used. This product takes the approach of rolling releases to provide continious delivery. Therefore, version details for affected and updated releases are not available. The project was informed of the problem early through an issue report but has not responded yet.

AnalysisAI

Unrestricted file upload in tittuvarghese CollegeManagementSystem exposes the Student Data Upload endpoint (dashboard_page/forms/upload_student_data.php) to remote exploitation by authenticated low-privilege users, allowing arbitrary file types - including PHP web shells - to be uploaded to the server by manipulating the Student-Data-CSV argument. All deployed instances across all commits are affected given the project's rolling release model, and no vendor-released patch exists as the maintainer has not responded to responsible disclosure. …

Vulnerability AssessmentAI

Exploitation The attacker must possess a valid low-privilege account on the target CollegeManagementSystem instance, as confirmed by the CVSS PR:L vector - unauthenticated external attackers cannot directly exploit this vulnerability without first obtaining credentials. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 6.3 Medium score (AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L) reflects network-accessible exploitation with low complexity but requires low-privilege authentication (PR:L), constraining the score. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An attacker holding any low-privilege CollegeManagementSystem account - such as a student account - crafts a multipart HTTP POST request to `dashboard_page/forms/upload_student_data.php`, substituting a PHP web shell for the expected CSV file in the Student-Data-CSV field. The server accepts and stores the file without type validation; the attacker then issues a GET request to the uploaded file's web-accessible path to trigger execution, gaining arbitrary OS command execution in the context of the web server process. …
Remediation No vendor-released patch has been identified at time of analysis; the maintainer has not responded to the responsible disclosure filed at https://github.com/tittuvarghese/CollegeManagementSystem/issues/2. … Detailed patch versions, workarounds, and compensating controls in full report.
