Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')

Score 6.3/10


The package snyk before 1.1064.0; the package snyk-mvn-plugin prior to 2.31.3; the package snyk-gradle-plugin prior to 3.24.5; the package @snyk/snyk-cocoapods-plugin prior to 2.5.3; the package snyk-sbt-plugin prior to 2.16.2; the package snyk-python-plugin prior to 1.24.2; the package snyk-docker-plugin prior to 5.6.5; ad the package @snyk/snyk-hex-plugin prior to 1.1.6 are vulnerable to Command Injection due to an incomplete fix for [CVE-2022-40764]( A successful exploit allows attackers to run arbitrary commands on the host system where the Snyk CLI is installed by passing in crafted command line flags. In order to exploit this vulnerability, a user would have to execute the snyk test command on untrusted files. In most cases, an attacker positioned to control the command line arguments to the Snyk CLI would already be positioned to execute arbitrary commands. However, this could be abused in specific scenarios, such as continuous integration pipelines, where developers can control the arguments passed to the Snyk CLI to leverage this component as part of a wider attack against an integration/build pipeline. This issue has been addressed in the latest Snyk Docker images available at as of 2022-11-29. Images downloaded and built prior to that date should be updated. The issue has also been addressed in the Snyk TeamCity CI/CD plugin as of version v20221130.093605.

CWE-78 - OS Command Injection

The OS command injection weakness (also known as shell injection) is a vulnerability which enables an attacker to run arbitrary OS commands on a server. This is done by modifying the intended downstream OS command and injecting arbitrary commands, enabling the execution of unauthorized OS commands. This has the potential to fully compromise the application along with all of its data, and, if the compromised process does not follow the principle of least privileges, it may compromise other parts of the hosting infrastructure as well. This weakness is listed as number ten in the 'CWE Top 25 Most Dangerous Software Weaknesses'.
