Detailsinfo

A vulnerability, which was classified as problematic, was found in NASA F Prime up to 4.2.x. Affected is some unknown processing. The manipulation 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 integrity, and availability. CVE summarizes:

F´ (F Prime) is a framework that enables development and deployment of spaceflight and other embedded software applications. Prior to 4.3.0, Svc::FileUplink handling of Fw::FilePacket::StartPacket destination paths FileUplink copies the packet-controlled destinationPath and opens it for writing without canonicalization or confinement to an upload directory. When a peer able to send file-uplink packets supplies an absolute, traversing, or otherwise attacker-selected writable destination path, files can be created or overwritten at attacker-selected writable filesystem locations, affecting integrity and potentially availability. This issue is fixed in version 4.3.0.

The advisory is shared for download at github.com. This vulnerability is traded as CVE-2026-92153 since 09/15/2026. The exploitability is told to be easy. It is possible to launch the attack remotely. There are neither technical details nor an exploit publicly available. The MITRE ATT&CK project declares the attack technique as T1006.

Upgrading to version 4.3.0 eliminates this vulnerability.
