CVE-2026-67972 Details
Description
An issue in the CF_CFDP_RecvMd() component of NASA cFS v7.0.1 allows attackers to contrl where received content and data is stored, possibly leading to an information disclosure.
A vulnerability in the CF_CFDP_RecvMd() component of NASA's Core Flight System (cFS) version 7.0.1 allows remote control over where received files are stored. This issue could lead to unintended information disclosure. The vulnerability arises because the CFDP receiver accepts destination filenames from remote metadata without proper validation, allowing files to be saved in arbitrary locations on the filesystem.
It is recommended to validate the destination filenames against a configured base directory before storing them. Absolute paths or any paths outside the approved receive root should be rejected. Additionally, path segments should be normalized to prevent traversal attacks.
