| Exploitation Conditions | No special conditions - remote unauthenticated exploitation against default configurations of code-projects Exam Form Submission 1.0. The /admin/delete_s4.php endpoint must be accessible, but no authentication or prior access is required. The vulnerability works over HTTP and does not require any specific feature to be enabled. |
| Impact | The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:L) indicates a network-accessible, low-complexity attack with no authentication needed, but with only low impact on confidentiality, integrity, and availability, resulting in a base score of 5.5 (medium). Despite the low CVSS score, the public availability of exploit code raises the practical risk for any deployed instance. The EPSS probability of 0.09% suggests limited exploitation activity, and the vulnerability is not in CISA's KEV, so it is not a current priority for emergency patching. However, because the application is likely a testing or educational tool, its deployment is rare, reducing overall exposure. |
| Exploit ScenarioDerived | An attacker sends an HTTP GET request to /admin/delete_s4.php?id=1' OR '1'='1' --, causing the SQL query to delete all records instead of a single one. The public exploit code on GitHub demonstrates this attack, making it trivial for anyone to replicate. |

Alert meAnalysisAIv1 – Jul 27, 2026
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.
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 If the application is no longer maintained, consider disabling or removing the vulnerable file entirely. The GitHub issue at https://github.com/mynlxx/CVE-ZhuChengQing/issues/8 may contain additional information.

Technical ContextAI · show details
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.
