Exploitation Conditions

No special conditions-remote unauthenticated exploitation against default configurations of code-projects Inventory Management System 1.0. The attack is launched via HTTP to the createUser.php endpoint, requiring no authentication or user interaction.

Impact

CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:L) yields a low base score (5.5), but the description and typical SQLi impact suggest higher severity (e.g., CVSS 3.1 would score 9.8). EPSS probability is very low (0.05%, 14th percentile), indicating low widespread exploitation, but public POC availability increases risk for targeted attacks. The vulnerability is not listed on CISA KEV. There is a conflict between the low CVSS impact metrics and the critical classification; the low impact in CVSS 4.0 may not reflect realistic consequences of unauthenticated SQLi.

Exploit ScenarioDerived

An attacker sends a crafted HTTP POST request to /php_action/createUser.php with a malicious SQL payload in the Username parameter, such as ' OR '1'='1, bypassing input validation and extracting database contents. Public exploit code is available, lowering the barrier for exploitation.

AnalysisAIv1 – Jul 28, 2026

SQL injection in code-projects Inventory Management System 1.0 allows remote unauthenticated attackers to manipulate the Username parameter in /php_action/createUser.php, leading to unauthorized data access or modification. Public exploit code is available (GitHub issue), but the EPSS exploitation probability is low (0.05%). The vulnerability is classified as critical despite a moderate CVSS base score, and no vendor-released patch has been identified.

RemediationAI

No vendor-released patch has been identified for this vulnerability. As a compensating control, deploy a web application firewall (WAF) with rules to block SQL injection patterns in the Username parameter, or restrict access to the /php_action/createUser.php endpoint using IP whitelisting or authentication if possible. If source code access is available, modify the script to use prepared statements or parameterized queries to prevent injection. These mitigations may impact functionality if the endpoint is required for legitimate user creation.

Technical ContextAI · show details

The vulnerability is a SQL injection (CWE-74) in a PHP-based inventory management system. The affected endpoint /php_action/createUser.php processes user-supplied input in the Username argument without proper sanitization or parameterized queries. The CPE (cpe:2.3:a:code-projects:inventory_management_system:1.0) confirms the exact product and version. SQL injection allows an attacker to inject arbitrary SQL commands into the underlying database, potentially compromising data integrity and confidentiality.
