# Log4shell
|
|
|
|
## Usage
|
|
|
|
`snyk log4shell`
|
|
|
|
## Description
|
|
|
|
The `snyk log4shell` command finds traces of the Log4J library that are affected by the Log4Shell vulnerability [CVE-2021-44228](https://security.snyk.io/vuln/SNYK-JAVA-ORGAPACHELOGGINGLOG4J-2314720)
|
|
|
|
The command finds traces of the Log4J library even if it is not declared in the manifest files (such as `pom.xml` or `build.gradle`).
|
|
|
|
## Managed projects
|
|
|
|
To test for Log4Shell vulnerabilities in Java projects using their package manager manifest files, use the `snyk test` command. See the [test command help](test.md) (`snyk test --help`) and [Java and Kotlin](https://docs.snyk.io/scan-using-snyk/supported-languages-and-frameworks/java-and-kotlin)
|
|
|
|
To test unmanaged files, use `snyk test --scan-all-unmanaged`
|
|
|
|
See the Maven options section of the [test command help](test.md); `snyk test --help`
