Summary

Khronos NNEF-Tools nnef through 1.0.10 and nnef-tools through 1.0.11 contain a path traversal flaw (CWE-22). Variable labels in a crafted graph.nnef file are not restricted to the model directory, so they can create or overwrite .dat files elsewhere on disk. A local attacker needs the victim to convert, save or generate weights from the crafted model. A public proof of concept is linked in the references.

Description from the CNA

Khronos NNEF-Tools nnef through 1.0.10 and nnef-tools through 1.0.11 contain a path traversal vulnerability that allows attackers to write files outside the model directory via crafted variable labels. Attackers can supply a graph.nnef with '../' sequences or absolute paths in labels to create or overwrite '.dat' files when users convert, save, or generate weights.
