Name of the Vulnerable Software and Affected Versions: Ubiquiti EdgeOS version 1.9.1

Description: The issue allows remote attackers to execute arbitrary code with admin credentials because the /opt/vyatta/share/vyatta-cfg/templates/system/static-host-mapping/host-name/node.def template does not sanitize the alias or ips parameter for shell metacharacters. This can be exploited through API endpoints related to system static host mapping.

Recommendations: For Ubiquiti EdgeOS version 1.9.1, consider disabling the alias and ips parameters in the /opt/vyatta/share/vyatta-cfg/templates/system/static-host-mapping/host-name/node.def template until a patch is available. Restrict access to the system static host mapping feature to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
