CVE-2017-7918

An Improper Access Control issue was discovered in Cambium Networks ePMP. After a valid user has used SNMP configuration export, an attacker is able to remotely trigger device configuration backups using specific MIBs. These backups lack proper access control and may allow access to sensitive information and possibly allow for configuration changes.
