CVE-2020-12149: OS Command Injection - Management File Upload

First published: Fri Dec 11 2020(Updated: )

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.

Remedy

The backup/restore functions in the patched versions of ECOS software have been modified to only accept alphanumeric characters, along with the period, hyphen, and underscore characters. This change ensures that OS commands cannot be injected via filename.
