DescriptionCVE.org

A vulnerability was determined in hemant6488 CodeIgniter-StudentManagementSystem. The affected element is an unknown function of the file /index.php/students/addStudentView of the component Student Management Handler. Executing a manipulation can lead to improper access controls. The attack can be executed remotely. The exploit has been publicly disclosed and may be utilized. This product implements a rolling release for ongoing delivery, which means version information for affected or updated releases is unavailable. The project was informed of the problem early through an issue report but has not responded yet.

AnalysisAI

Improper access control in hemant6488's CodeIgniter-StudentManagementSystem exposes the student addition endpoint at /index.php/students/addStudentView to unauthenticated remote manipulation, enabling read, write, and partial availability impact on student data without credentials. The CVSS 4.0 vector (PR:N, AV:N, AC:L) confirms no authentication is required from any network, and a publicly available exploit (GitHub issue #5) has been documented. …

Vulnerability AssessmentAI

Exploitation The addStudentView endpoint (/index.php/students/addStudentView) must be reachable over the network - exploitation is straightforward against any internet-facing deployment, which is the typical configuration for web-based student management systems. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 4.0 score of 5.5 (Medium) with vector AV:N/AC:L/AT:N/PR:N/UI:N reflects low-complexity unauthenticated network exploitation requiring no user interaction, though the impact metrics VC:L/VI:L/VA:L constrain it to partial confidentiality, integrity, and availability effects rather than full system compromise. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An unauthenticated remote attacker identifies a publicly accessible instance of CodeIgniter-StudentManagementSystem by scanning for the characteristic /index.php/students/addStudentView URL path. Using the publicly documented exploit technique from GitHub issue #5, the attacker sends a crafted HTTP request that bypasses the missing access control check, enabling them to read, insert, or manipulate student records. …
Remediation No vendor-released patch has been identified at time of analysis; the maintainer has not responded to the disclosure reported via GitHub issue #5 (https://github.com/hemant6488/CodeIgniter-StudentManagementSystem/issues/5). … Detailed patch versions, workarounds, and compensating controls in full report.
