XSS in the /files Endpoint of the Generic REST API

Moderate severity GitHub Reviewed Published Apr 22, 2025 in cuba-platform/restapi • Updated Apr 23, 2025

Package

maven com.haulmont.addon.restapi:restapi-rest-api (Maven)

Affected versions

< 7.2.7

Patched versions

7.2.7

Description

Impact

The input parameter, which consists of a file path and name, can be manipulated to return the Content-Type header with text/html if the name part ends with .html. This could allow malicious JavaScript code to be executed in the browser. For a successful attack, a malicious file needs to be uploaded beforehand.

The severity of the vulnerability is mitigated by the fact that the application UI and the generic REST API are typically accessible only to authenticated users.

Patches

The problem has been fixed in CUBA REST API add-on 7.2.7.

Workarounds

A workaround for those who are unable to upgrade: Disable Files Endpoint in CUBA Application.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
