Detailsinfo

A vulnerability was found in Eclipse aeriOS up to 1.2.1. It has been rated as very critical. This issue affects an unknown part of the component REST API. The manipulation with an unknown input leads to a path traversal vulnerability. Using CWE to declare the problem leads to 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. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

Eclipse aeriOS Self-orchestrator versions prior to 1.2.1 contain a path traversal vulnerability in the REST API. User-controlled identifiers used to create, update, or delete Self-orchestrator resources were incorporated into filesystem paths without adequate validation or sanitization. An unauthenticated remote attacker able to access the Self-orchestrator API could therefore supply specially crafted identifiers containing path traversal sequences to write or delete JSON files outside the intended application directories, subject to the filesystem permissions of the Self-orchestrator process. The impact is increased by the absence of authentication on the affected API and by the container running with elevated privileges in the affected deployment configuration. The issue has been addressed in version 1.2.1 by introducing validation and sanitization of user-controlled identifiers before they are used to construct filesystem paths, preventing path separator characters from being used to escape the intended directories.

The advisory is shared at gitlab.eclipse.org. The identification of this vulnerability is CVE-2026-85199 since 09/03/2026. The exploitation is known to be easy. The attack may be initiated remotely. No form of authentication is needed for a successful exploitation. Neither technical details nor an exploit are publicly available. The price for an exploit might be around USD $0-$5k at the moment (estimation calculated on 09/03/2026). MITRE ATT&CK project uses the attack technique T1006 for this issue.

Applying the patch c42da0014069528d149ff9f8b038ac93c38a766c is able to eliminate this problem.
