CVE-2026-67970 Details
Description
Incorrect access control in the DS_SetDestPathCmd() component of NASA cFS v7.0.1 allows attackers to access sensitive components via a path traversal.
A path traversal vulnerability has been identified in the DS_SetDestPathCmd() component of NASA's cFS version 7.0.1. This vulnerability allows attackers to manipulate the destination filename's basename, steering file output into unintended directories. The issue arises because the DS component does not properly validate basename inputs, enabling the inclusion of path separators that traverse the filesystem hierarchy.
It is recommended to enforce strict validation on basename inputs, rejecting any path separators, control bytes, or sequences that could influence directory traversal. Additionally, implementing a canonicalization process to ensure compliance with a mission-approved policy before accepting basename values could help mitigate this vulnerability.
