Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-284: Improper Access Control, where the product does not restrict or incorrectly restricts access to a resource from an unauthorized actor. In Unopim/unopim, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Summary In Unopim, it is possible to create roles and choose the privileges. However, users without the “Delete” privilege for Products cannot delete a single product via the standard endpoint (expected behavior), but can still delete products via the mass-delete endpoint, even when the request contains only one product ID. **Severity**: High CVSS Score 8.1 (CVSS 3.1 Vector: [AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:H](https://nvd.nist.gov/vuln-metrics/cvss/v3-calculator?vector=AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:H&version=3.1)) **Category**: Broken Access Control / Missing Authorization (OWASP A01:2021) **Impact**: Unauthorized product deletion -> data loss, possible business disruption ### Affected Behavior **Single delete (enforced):** **DELETE** `/admin/catalog/products/{id}` returns 401 with "This action is unauthorized" for users lacking the Delete privilege. **Mass delete (not enforced):** **POST** `/admin/catalog/products/mass-delete` allows deletion without the Delete privilege. This occurs for both multiple IDs and a single ID submitted to the bulk endpoint. ### PoC A video was captured in Burp Suite for a proof of concept.
