CVE-2026-67979Public exploitNetwork attack vector

Remote code execution via unverified shared-object loading

Published Aug 4, 2026 · Updated Aug 4, 2026

Improper access control in NASA cFS 7.0.1 allows remote attackers to execute arbitrary code by loading a shared object from writable storage. The CFDP receive path retains an attacker-supplied module, and CFE_ES_START_APP_CC accepts its path and entry point without verifying the module's identity or trust. The demonstrated chain requires CI_LAB and CFDP ingress plus access to the StartApp command; root execution was shown only inside the sample container.
