Analysis

Impact

The vulnerability lies in the delete_post.php handler of SourceCodester Simple E-learning System, where an attacker can supply a crafted post_id via the HTTP GET parameter. This manipulation allows arbitrary SQL statements to be executed against the database, potentially exposing, modifying, or deleting sensitive course and user data. The flaw stems from insufficient input validation and direct inclusion of the parameter in SQL queries (CWE-89).

Affected Systems

The flaw exists in SourceCodester Simple E-learning System version 1.0, specifically within the file /includes/form_handlers/delete_post.php. No other variants or versions were identified in the CVE data.

Risk and Exploitability

The CVSS score of 5.3 indicates a moderate risk, and while no EPSS value is available, the vulnerability was publicly disclosed and can be exploited remotely by sending a crafted URL with a malicious post_id. Since it does not appear in the CISA KEV catalog, the current threat level is moderate but non-negligible. Exploitation requires only network access to the application and does not necessitate authentication.

Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

Apply the latest patch from SourceCodester for Simple E-learning System v1.0 that sanitizes the post_id parameter.
If no patch is available, restrict direct access to delete_post.php using web server rules such as IP whitelisting or disabling the endpoint temporarily.
Modify the code to cast post_id to an integer and bind it as a parameter in prepared SQL statements.
Enable application logging and monitor for suspicious DELETE or UPDATE queries involving the posts table.
Conduct a review of all input points in the application for similar SQL injection risks and remediate accordingly.
