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

CVE-2020-12149

High
8.5/10

Summary

The configuration backup/restore function in Silver Peak Unity ECOSTM (ECOS) appliance software was found to directly incorporate the user-controlled config filename in a subsequent shell command, allowing an attacker to manipulate the resulting command by injecting valid OS command input. This vulnerability can be exploited by an attacker with authenticated access to the Orchestrator UI or EdgeConnect UI. This affects all ECOS versions prior to: 8.1.9.15, 8.3.0.8, 8.3.1.2, 8.3.2.0, 9.0.2.0, and 9.1.0.0.

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'.
