CVE-2025-25371Public exploitNetwork attack vector

Arbitrary file overwrite via prefix-only path validation

Published Mar 25, 2025 · Updated Mar 26, 2025

Path traversal in NASA cFS Aquila OSAL allows remote attackers to overwrite arbitrary files by supplying crafted file paths. OS_TranslatePath checks only whether an untrusted path begins with the virtual mount-point string, without resolving parent-directory segments before OS_OpenCreate uses it. Unauthenticated network access is sufficient, and writes remain limited to locations accessible to the cFS process.
