CWE-618 暴露的不安全ActiveX方法

Exposed Unsafe ActiveX Method

结构: Simple

Abstraction: Base

状态: Incomplete

被利用可能性: unkown

基本描述

An ActiveX control is intended for use in a web browser, but it exposes dangerous methods that perform actions that are outside of the browser's security model (e.g. the zone or domain).

扩展描述

ActiveX controls can exercise far greater control over the operating system than typical Java or javascript. Exposed methods can be subject to various vulnerabilities, depending on the implemented behaviors of those methods, and whether input validation is performed on the provided arguments. If there is no integrity checking or origin validation, this method could be invoked by attackers.

可能的缓解方案

Implementation

策略:

If you must expose a method, make sure to perform input validation on all arguments, and protect against all possible vulnerabilities.

Architecture and Design

策略:

Use code signing, although this does not protect against any weaknesses that are already in the control.

['Architecture and Design', 'System Configuration']

策略:

Where possible, avoid marking the control as safe for scripting.
