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


Severity High
Score 7.8/10


Snyk CLI before 1.996.0 allows arbitrary command execution, affecting Snyk IDE plugins and the snyk npm package. Exploitation could follow from the common practice of viewing untrusted files in the Visual Studio Code editor, for example. The original demonstration was with shell metacharacters in the vendor.json ignore field, affecting snyk-go-plugin before 1.19.1. This affects, for example, the Snyk TeamCity plugin (which does not update automatically) before 20220930.142957.

CWE-77 - Command Injection

A command injection attack involves injecting an operating system command through the data input, which gets executed on the host operating system with the privileges of the victimized application. The impact of a command injection attack may range from loss of data confidentiality and integrity to unauthorized remote access to the hosting system. The attack may cause serious data breaches and system takeover.
