Detailsinfo

A vulnerability was found in Eclipse BaSyx up to 2.0.0-milestone-9. It has been classified as critical. Affected is an unknown code block of the component Submodel HTTP API. The manipulation of the argument fileName with an unknown input leads to a path traversal vulnerability. CWE is classifying the issue as CWE-22. The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

In Eclipse BaSyx Java Server SDK versions prior to 2.0.0-milestone-10, inadequate path normalization in the Submodel HTTP API allows an unauthenticated remote attacker to perform a path traversal attack. By supplying a maliciously crafted fileName parameter during a file upload operation, an attacker can bypass intended storage boundaries and write arbitrary files to any location on the host filesystem accessible by the Java process. This can lead to Remote Code Execution (RCE) and complete system compromise.

The weakness was disclosed by Mohamed Lemine Ahmed Jidou as 102. The advisory is shared for download at gitlab.eclipse.org. This vulnerability is traded as CVE-2026-7411 since 04/29/2026. The exploitability is told to be easy. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. There are known technical details, but no exploit is available. The MITRE ATT&CK project declares the attack technique as T1006.

Upgrading to version 2.0.0-milestone-10 eliminates this vulnerability.
