DescriptionCVE.org

A vulnerability was identified in SourceCodester Inventory System 1.0. Affected is an unknown function of the file /users.php of the component User Management Page. The manipulation of the argument fullname/username leads to cross site scripting. The attack is possible to be carried out remotely. The exploit is publicly available and might be used.

When an authenticated user - likely an administrator - visits the affected page, the injected script executes in their browser session, enabling session hijacking, credential theft, or unauthorized UI manipulation. …

Vulnerability AssessmentAI

Exploitation The attacker must be able to reach the /users.php endpoint over the network (AV:N) - the application is PHP/MySQL-based and typically HTTP-exposed. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS base score of 4.3 (Medium) reflects the low integrity-only impact (I:L) and required user interaction (UI:R), which mechanically suppresses the score. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An unauthenticated external attacker submits a crafted HTTP POST request to /users.php with a fullname or username value containing a JavaScript payload (e.g., a session cookie-stealing script). The payload is stored in the application database without sanitization. …
Remediation No vendor-released patch has been identified at time of analysis - the CVSS RL:X modifier and absence of any advisory from SourceCodester confirm this. … Detailed patch versions, workarounds, and compensating controls in full report.

Threat intelligence, references, and detailed analysis are available after sign-in.
