CWE-15: External Control of System or Configuration Setting
CWE版本: 4.18
更新日期: 2025-09-09
弱点描述
One or more system settings or configuration elements can be externally controlled by a user.
扩展描述
Allowing external control of system settings can disrupt service or cause an application to behave in unexpected, and potentially malicious ways.
常见后果
影响范围: Other
技术影响: Varies by Context
潜在缓解措施
阶段: Architecture and Design
策略: Separation of Privilege
阶段: Implementation Architecture and Design
描述: Because setting manipulation covers a diverse set of functions, any attempt at illustrating it will inevitably be incomplete. Rather than searching for a tight-knit relationship between the functions addressed in the setting manipulation category, take a step back and consider the sorts of system values that an attacker should not be allowed to control.
阶段: Implementation Architecture and Design
描述: In general, do not allow user-provided or otherwise untrusted data to control sensitive values. The leverage that an attacker gains by controlling these values is not always immediately obvious, but do not underestimate the creativity of the attacker.
检测方法
方法: 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.)
有效性: High
引入模式
| 阶段 | 说明 |
|---|---|
| Implementation | Setting manipulation vulnerabilities occur when an attacker can control values that govern the behavior of the system, manage specific resources, or in some way affect the functionality of the application. |
| Implementation | REALIZATION: This weakness is caused during implementation of an architectural security tactic. |
