Vulnerability details

Unitree Go1 <= Go1_2022_05_11 is vulnerable to Insecure Permissions as the firmware update functionality (via Wi-Fi/Ethernet) implements an insecure verification mechanism that solely relies on MD5 checksums for firmware integrity validation.

Why these techniques?

Insecure MD5-only verification in the network-exposed firmware update service (Wi-Fi/Ethernet) enables remote exploitation of a public-facing application (T1190) and remote services (T1210) to achieve remote code execution and privilege escalation (T1068).

Mitigating Controls

Likely Mitigating Controls AI

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.

AC-1 Policy and Procedures
addresses: CWE-276

Access control policy can specify and enforce secure default permissions for resources.

AC-6 Least Privilege
addresses: CWE-276

Guides setting of default permissions to the minimum required level.

CM-1 Policy and Procedures
addresses: CWE-276

Establishes requirements for appropriate default permissions on system resources as part of configuration management.

CM-2 Baseline Configuration
addresses: CWE-276

Baseline establishment and updates on install/upgrade ensure correct default permissions rather than insecure ones.

CM-6 Configuration Settings
addresses: CWE-276

Requiring the most restrictive settings instead of defaults prevents incorrect default permissions on resources.

CM-9 Configuration Management Plan
addresses: CWE-276

Requires documented processes that include setting and maintaining correct default permissions for configuration items.

PE-1 Policy and Procedures
addresses: CWE-276

Requires addressing secure default permissions in physical and environmental protection controls.

PL-11 Baseline Tailoring
addresses: CWE-276

Tailoring explicitly overrides or scopes default permission assignments in the baseline to match the system's actual risk and operational needs.
