Lifecycle Timeline
2DescriptionCVE.org
A vulnerability has been found in code-projects Exam Form Submission 1.0 and classified as critical. Affected by this vulnerability is an unknown functionality of the file /admin/delete_s4.php. The manipulation of the argument ID leads to sql injection. The attack can be launched remotely. The exploit has been disclosed to the public and may be used.
AnalysisAI
SQL injection in code-projects Exam Form Submission 1.0 allows remote unauthenticated attackers to extract or modify database contents via the /admin/delete_s4.php endpoint. Public exploit code is available, increasing the risk of scanning and exploitation, though no active exploitation has been confirmed (not listed in CISA KEV). The EPSS score is low (0.09%), indicating a lower likelihood of mass exploitation at this time.
Technical ContextAI
This is a SQL injection (CWE-74) vulnerability in the delete_s4.php script, which likely handles deletion of exam submission records. The PHP application interacts with a MySQL database; the ID parameter passed in the HTTP request is directly concatenated into an SQL query without sanitization, allowing an attacker to inject arbitrary SQL commands. The CPE string cpe:2.3:a:code-projects:exam_form_submission:1.0 confirms the affected product is version 1.0 of this educational project.
RemediationAI
No official patch from the vendor has been identified. The primary remediation is to apply input validation and parameterized queries (prepared statements) to the ID parameter in delete_s4.php. Alternatively, restrict access to the /admin/ directory using .htaccess or a web application firewall (WAF) to block external requests to admin functions. If the application is no longer maintained, consider disabling or removing the vulnerable file entirely.
