Tên: Exposed Unsafe ActiveX Method
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).

| Phạm vi | Tác động | Khả năng xảy ra |
|---|---|---|
| Other | Varies by Context Ghi chú: If there is no integrity checking or origin validation, this method could be invoked by attackers. Since ActiveX controls can exercise far greater control over the operating system than typical Java or javascript, exposed methods can be subject to various vulnerabilities. Consequences depend on the implemented behaviors of those methods, and whether input validation is performed on the provided arguments. |

Các biện pháp giảm thiểu tiềm năng
Phases : ImplementationIf you must expose a method, make sure to perform input validation on all arguments, and protect against all possible vulnerabilities.
Phases : Architecture and Design
Use code signing, although this does not protect against any weaknesses that are already in the control.
Phases : Architecture and Design // System Configuration
Where possible, avoid marking the control as safe for scripting.
Phương pháp phát hiện
Automated Static Analysis
Automated static analysis, commonly referred to as Static Application Security Testing (SAST), can find some instances of this weakness by analyzing source code (or binary/compiled code) without having to execute it. Typically, this is done by building a model of data flow and control flow, then searching for potentially-vulnerable patterns that connect "sources" (origins of input) with "sinks" (destinations where the data interacts with external components, a lower layer such as the OS, etc.)Hiệu quả : High
Ghi chú ánh xạ lỗ hổng
Lý do : This CWE entry is at the Variant level of abstraction, which is a preferred level of abstraction for mapping to the root causes of vulnerabilities.Bình luận : Carefully read both the name and description to ensure that this mapping is an appropriate fit. Do not try to 'force' a mapping to a lower-level Base/Variant simply to comply with this preferred level of abstraction.
