CVE-2018-19393 — Cobham Satcom Sailor 800 Firmware security vulnerability
Cobham Satcom Sailor 800 and 900 devices contained a vulnerability that allowed for arbitrary writing of content to the system's configuration file. This was exploitable via multiple attack vectors depending on the device's configuration. Further analysis also indicated this vulnerability could be leveraged to achieve a Denial of Service (DoS) condition, where the device would require a factory reset to return to normal operation.

Privilege escalation and unsafe privilege management
This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.
Check exposure
- Map service accounts, operating-system identities, roles, capabilities, impersonation, set-user transitions, and administrative helper paths.
- Determine whether untrusted users or lower-privilege processes can reach the affected transition or modify inputs it trusts.
- Review file, socket, registry, device, job, container, and cloud-role permissions used before and after privilege changes.
Remediate safely
- Apply the supported fix and redesign privileged operations as a minimal, authenticated, allowlisted interface.
- Drop privileges before processing untrusted input, verify the drop succeeds, and remove unnecessary roles, capabilities, and write permissions.
- Validate ownership and permissions at time of use and add explicit lower-to-higher privilege boundary tests.
