If we are in this case due to one of the following conditions, it's a good idea to start a parallel study to find another component better maintained or if it's a commercial component with support then put pressure on the provider with the help of your Chief Risk Officer (fallback possible to Chief Information Security Officer) Provider does not want to fix the issue. Provider does not answer at all. In all cases, here, we need to handle the vulnerability right now. As we know the vulnerable dependency, we know where it is used in the application (if it's a transitive dependency then we can identify the first level dependency using it using the IDE built-in feature or the dependency management system used (Maven, Gradle, NuGet, npm, etc.). Note that IDE is also used to identify the calls to the dependency. Identifying calls to this dependency is fine but it is the first step. The team still lacks information on what kind of patching needs to be performed. To obtain these information, the team uses the CVE content to know which kind of vulnerability affects the dependency. The description property provides the answer: SQL injection, Remote Code Execution, Cross-Site Scripting, Cross-Site Request Forgery, etc. After identifying the above 2 points, the team is aware of the type of patching that needs to be taken (Case 2 with the protective code) and where to add it. The team has an application using the Jackson API in a version exposed to the CVE-2016-3720. The description of the CVE is as follows Bounded code example (external data; do not execute automatically): ```text XML external entity (XXE) vulnerability in XmlMapper in the Data format extension for Jackson (aka jackson-dataformat-xml) allows attackers to have unspecified impact via unknown vectors. ``` Based on these information, the team determines that the necessary patching will be to add a pre-validation of any XML data passed to the Jakson API to prevent XML external entity (XXE) vulnerability. If possible, create a unit test that mimics the vulnerability in order to ensure that the patch is effective and have a way to continuously ensure that the patch is in place during the evolution of the project. … Attribution: Adapted from OWASP Cheat Sheet Series under CC-BY-SA-4.0.
