Executive brief
jshERP, an open-source Enterprise Resource Planning (ERP) system used by small and medium-sized businesses, contains a security flaw in its access control mechanisms. An unauthorized attacker can exploit this to view sensitive account information, including user IDs and encrypted passwords. By obtaining this data, an attacker could potentially take over administrative or user accounts, leading to a full compromise of the business's financial, sales, and inventory data.
Technical details
An Insecure Direct Object Reference (IDOR) vulnerability exists in jshERP v3.5 within the `ResourceController.java` component, specifically affecting the `getList` method. The flaw stems from incorrect access control checks when processing requests to the `/user/info` endpoint. An unauthenticated remote attacker can use path traversal techniques (e.g., `../../user/info`) and modify the `id` parameter to retrieve sensitive information for any user in the system. This data includes account details and password hashes, which can be further exploited to perform unauthorized logins and gain full access to the ERP environment.
