DescriptionCVE.org

A security vulnerability has been detected in SourceCodester CET Automated Grading System with AI Predictive Analytics 1.0. Affected is an unknown function of the file /index.php of the component Student Self-Registration Endpoint. The manipulation leads to improper access controls. Remote exploitation of the attack is possible.

AnalysisAI

Improper access control in SourceCodester CET Automated Grading System with AI Predictive Analytics 1.0 exposes the Student Self-Registration Endpoint (/index.php) to unauthenticated remote exploitation. The CWE-284 root cause, combined with the 'Authentication Bypass' tag, indicates that the self-registration flow fails to enforce intended access boundaries, potentially allowing unauthenticated users to access, manipulate, or enumerate data beyond their authorized scope. …

Vulnerability AssessmentAI

Exploitation	No special conditions are required for network access - the Student Self-Registration Endpoint (/index.php) is a publicly accessible PHP endpoint designed for unauthenticated users to register. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment	The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:N) indicates network-reachable, low-complexity, unauthenticated exploitation with no special attack requirements - a straightforward attack profile. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario	An unauthenticated remote attacker sends a crafted HTTP request to the publicly accessible /index.php Student Self-Registration Endpoint, manipulating parameters to bypass the application's access control checks. No public exploit code has been identified at time of analysis, but the low attack complexity (AC:L) and absence of authentication requirements (PR:N) mean that manual exploitation requires minimal skill once the specific parameter manipulation is identified. …
Remediation	No vendor-released patch has been identified at time of analysis. … Detailed patch versions, workarounds, and compensating controls in full report.
