| Package | Affected versions | Patched versions |
|---|---|---|
| io.jmix.localfs:jmix-localfs | ≥ 1.0.0, < 1.6.2≥ 2.0.0, < 2.4.0 | 1.6.22.4.0 |
| jmix framework | ≥ 1.0.0, < 1.6.2≥ 2.0.0, < 2.4.0 | 1.6.22.4.0 |
Attackers could manipulate the FileRef parameter to access files on the system where the Jmix application is deployed, provided the application server has the necessary permissions. This can be accomplished either by modifying the FileRef directly in the database or by supplying a harmful value in the fileRef parameter of the /files endpoint of the generic REST API.
Arbitrary file reading on the operating system where the Jmix process is running.
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. Additionally, the /files endpoint in Jmix requires specific permissions and is disabled by default.
A workaround for those who are unable to upgrade: Fix Path Traversal in Jmix Application.
