Description

InvenTree is an Open Source Inventory Management System. Prior to version 1.2.3, insecure server-side templates can be hijacked to expose secure information to the client. When generating custom batch codes, the InvenTree server makes use of a customizable jinja2 template, which can be modified by a staff user to exfiltrate sensitive information or perform code execution on the server. This issue requires access by a user with granted staff permissions, followed by a request to generate a custom batch code via the API. Once the template has been modified in a malicious manner, the API call to generate a new batch code could be made by other users, and the template code will be executed with their user context. The code has been patched to ensure that all template generation is performed within a secure sandboxed context. This issue has been addressed in version 1.2.3, and any versions from 1.3.0 onwards. Some workarounds are available. The batch code template is a configurable global setting which can be adjusted via any user with staff access. To prevent this setting from being edited, it can be overridden at a system level to a default value, preventing it from being edited. This requires system administrator access, and cannot be changed from the client side once the server is running. It is recommended that for InvenTree installations prior to 1.2.3 the STOCK_BATCH_CODE_TEMPLATE and PART_NAME_FORMAT global settings are overridden at the system level to prevent editing.

How this vulnerability can be exploited

This issue can be reached from an adjacent network, attack complexity is low, an attacker needs low-level privileges on the target. A user must be tricked into taking some action. The scope is changed, meaning a successful attack can affect components beyond the vulnerable one. Rated impact: confidentiality low, integrity low, availability low.

CVSS metrics in full

The score comes from this vector: CVSS:3.1/AV:A/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:L

  • Attack vector: Adjacent network — the attacker has to sit on the same local or logical network.
  • Attack complexity: Low — the attack works reliably, with no preparation.
  • Privileges required: Low — an ordinary user account is enough.
  • User interaction: Required — someone has to click, open or visit something.
  • Scope: Changed — a successful attack reaches components beyond the vulnerable one.
  • Confidentiality impact: Low — limited, and the attacker does not choose what is affected.
  • Integrity impact: Low — limited, and the attacker does not choose what is affected.
  • Availability impact: Low — limited, and the attacker does not choose what is affected.
