CWE-99: Improper Control of Resource Identifiers ('Resource Injection')
CWE版本: 4.18
更新日期: 2025-09-09
弱点描述
The product receives input from an upstream component, but it does not restrict or incorrectly restricts the input before it is used as an identifier for a resource that may be outside the intended sphere of control.
常见后果
影响范围: Confidentiality Integrity
技术影响: Read Application Data Modify Application Data Read Files or Directories Modify Files or Directories
说明: An attacker could gain access to or modify sensitive data or system resources. This could allow access to protected files or directories including configuration files and files containing sensitive information.
潜在缓解措施
阶段: Implementation
策略: Input Validation
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
观察示例
参考: CVE-2013-4787
chain: mobile OS verifies cryptographic signature of file in an archive, but then installs a different file with the same name that is also listed in the archive.
