01

What, why and how

A vulnerability has been found in SourceCodester Syllabus-Aligned Learning Management & Examination System 1.0. Impacted is an unknown function of the file delete_exam.php. The manipulation of the argument ID leads to authorization bypass. The attack is possible to be carried out remotely. The exploit has been disclosed to the public and may be used.

What

A vulnerability has been found in SourceCodester Syllabus-Aligned Learning Management & Examination System 1.0. Impacted is an unknown function of the file delete_exam.php. The manipulation of the argument ID leads to authorization bypass. The attack is possible to be carried out remotely. The exploit has been disclosed to the public and may be used.

Why

The system's authorization functionality does not prevent one user from gaining access to another user's data or record by modifying the key value identifying the data.

How

An attacker operating through a network path may attempt exploitation without authentication or user interaction. If successful, the issue may cause the confidentiality, integrity or availability impact described by the vendor.

Exploit reality and attack path

CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.

Observed exploitation
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
No confirmed evidence

No CISA KEV match was present at the last successful refresh. This means no confirmation from that source, not proof of no exploitation.

Public PoC / exploit material
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
Reference recorded

CISA Vulnrichment records proof-of-concept exploitation in its SSVC data. BlackTree has not independently executed or validated exploit material.

Likely attack path
a network path → Authorization Bypass Through User-Controlled Key → cause the confidentiality, integrity or availability impact described by the vendor
