CVE-2020-12149

11.12.2020, 16:15

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.

Common Weakness Enumeration

CWE-78 - Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')
The software constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component.
