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


Severity High
Score 9.8/10


An issue was discovered in SaltStack Salt affecting versions prior to 2019.2.6, from 3000 before 3000.4, from 3001 before 3001.2, and from 3002 before 3002.1. Sending crafted web requests to the Salt API, with the SSH client enabled, can result in shell injection. The following versions have received a patch: 2015.8.10, 2015.8.13, 2016.3.4, 2016.3.6, 2016.3.8, 2016.11.3, 2016.11.6, 2016.11.10, 2017.7.4, 2017.7.8, 2018.3.5, 2019.2.5, 2019.2.6, 3000.3, 3000.4, 3001.1, 3001.2, and 3002.

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'.
