名称: Incorrect Initialization of Resource
The product attempts to initialize a resource but does not correctly do so, which might leave the resource in an unexpected, incorrect, or insecure state when it is accessed.

|---|---|
CVE-2020-27211 | Chain: microcontroller system-on-chip uses a register value stored in flash to set product protection state on the memory bus and does not contain protection against fault injection (CWE-1319) which leads to an incorrect initialization of the memory bus (CWE-1419) causing the product to be in an unprotected state. |
CVE-2023-25815 | Chain: a change in an underlying package causes the gettext function to use implicit initialization with a hard-coded path (CWE-1419) under the user-writable C:\ drive, introducing an untrusted search path element (CWE-427) that enables spoofing of messages. |
CVE-2022-43468 | WordPress module sets internal variables based on external inputs, allowing false reporting of the number of views |
CVE-2022-36349 | insecure default variable initialization in BIOS firmware for a hardware board allows DoS |
CVE-2015-7763 | distributed filesystem only initializes part of the variable-length padding for a packet, allowing attackers to read sensitive information from previously-sent packets in the same memory location |
潜在缓解措施
Phases : ImplementationChoose the safest-possible initialization for security-related resources.
Phases : Implementation
Ensure that each resource (whether variable, memory buffer, register, etc.) is fully initialized.
Phases : Implementation
Pay close attention to complex conditionals or reset sources that affect initialization, since some paths might not perform the initialization.
Phases : Architecture and Design
Ensure that the design and architecture clearly identify what the initialization should be, and that the initialization does not have security implications.
检测方法
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.)漏洞映射说明
