Likely Mitigating ControlsAI

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.

MITRE ATT&CK Enterprise TechniquesAI

T1574.005 Executable Installer File Permissions Weakness Stealth
Adversaries may execute their own malicious payloads by hijacking the binaries used by an installer.

Why these techniques?

Insecure default directory permissions during installation directly enable modification of temp files for arbitrary component deployment, matching Executable Installer File Permissions Weakness.

Confidence: HIGH · MITRE ATT&CK Enterprise v18.1

NVD Description

The affected product creates a directory with insecure default permissions during administrative installation. This allows a low-privileged local attacker to modify a temporary file defining the components to be installed, enabling local privilege escalation by forcing the deployment of arbitrary…
