DescriptionCVE.org

A weakness has been identified in Rizwan17 inventory-management-system up to bfe78a330d01bb26b9daec5dc9ecd5c77900e03f. Affected by this vulnerability is the function createUserAccount of the file register.php of the component Registration Handler. Executing a manipulation of the argument usertype can lead to improper authorization. It is possible to launch the attack remotely. The exploit has been made available to the public and could be used for attacks. This product takes the approach of rolling releases to provide continious delivery. Therefore, version details for affected and updated releases are not available. The project was informed of the problem early through an issue report but has not responded yet.

AnalysisAI

Privilege escalation through parameter manipulation in Rizwan17's inventory-management-system allows remote unauthenticated attackers to register accounts with arbitrary privilege levels, including administrative roles, by supplying a crafted usertype value to the createUserAccount function in register.php. The vulnerability stems from the registration handler trusting client-controlled role values without server-side enforcement of permitted self-registration tiers. …
