Common Weakness Enumeration
- CWE-281 - Improper Preservation of PermissionsThe software does not preserve permissions or incorrectly preserves permissions when copying, restoring, or sharing objects, which can cause them to have less restrictive permissions than intended.
- CWE-78 - Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')The software constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component.
