DescriptionCVE.org

A flaw has been found in SourceCodester Onlne Examination & Learning Management System 1.0. The impacted element is an unknown function of the file register.php of the component Registration Endpoint. Executing a manipulation of the argument role can lead to improper privilege management. The attack can be executed remotely. The exploit has been published and may be used. The name of the affected product appears to have a typo in it.

AnalysisAI

Privilege escalation in SourceCodester's Onlne Examination & Learning Management System 1.0 (the product name itself contains a typo - 'Onlne' instead of 'Online') exposes an unauthenticated registration endpoint at register.php where the role parameter is not server-side validated, allowing any remote actor to self-assign elevated privileges at account creation. A publicly available exploit has been published on Pastebin, confirming the attack is trivially reproducible. …

Vulnerability AssessmentAI

Exploitation The registration endpoint at register.php must be publicly accessible (i.e., open self-registration must be enabled, which is the default configuration for this type of platform). … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 4.0 base score of 5.5 is supported by a vector of AV:N/AC:L/AT:N/PR:N/UI:N with limited impact metrics (VC:L/VI:L/VA:L), which accurately reflects that exploitation is trivial and unauthenticated but impact is bounded to the application's own privilege domain rather than the underlying host. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An attacker visits the publicly accessible register.php endpoint and submits a crafted HTTP POST request with the role parameter set to a privileged value such as 'admin' or 'instructor'. The application inserts the attacker-supplied role directly into the user record without validation, granting the newly created account elevated privileges. …
Remediation No vendor-released patch has been identified at time of analysis; the CPE wildcard and absence of a vendor advisory confirm no fixed version is available. … Detailed patch versions, workarounds, and compensating controls in full report.
