Dependency on Vulnerable Third-Party Component

The product has a dependency on a third-party component that contains one or more known vulnerabilities.


Many products are large enough or complex enough that part of their functionality uses libraries, modules, or other intellectual property developed by third parties who are not the product creator. For example, even an entire operating system might be from a third-party supplier in some hardware products. Whether open or closed source, these components may contain publicly known vulnerabilities that could be exploited by adversaries to compromise the product.


The following examples help to illustrate the nature of this weakness and describe methods or techniques which can be used to mitigate the risk.

Note that the examples here are by no means exhaustive and any given weakness may have many subtle varieties, each of which may require different detection methods or runtime controls.

Example One

The "SweynTooth" vulnerabilities in Bluetooth Low Energy (BLE) software development kits (SDK) were found to affect multiple Bluetooth System-on-Chip (SoC) manufacturers. These SoCs were used by many products such as medical devices, Smart Home devices, wearables, and other IoT devices. [REF-1314] [REF-1315]

Example Two

log4j, a Java-based logging framework, is used in a large number of products, with estimates in the range of 3 billion affected devices [REF-1317]. When the "log4shell" (CVE-2021-44228) vulnerability was initially announced, it was actively exploited for remote code execution, requiring urgent mitigation in many organizations. However, it was unclear how many products were affected, as Log4j would sometimes be part of a long sequence of transitive dependencies. [REF-1316]
