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

CVE-2019-14904

Severity High
Score 7.3/10

Summary

A flaw was found in the solaris_zone module from the Ansible Community modules. When setting the name for the zone on the Solaris host, the zone name is checked by listing the process with the 'ps' bare command on the remote machine. An attacker could take advantage of this flaw by crafting the name of the zone and executing arbitrary commands in the remote host. Ansible Engine 2.7.15, 2.8.7, 2.9.2, and 2.10.0b1 as well as previous versions are affected.

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'.
