The below vulnerabilities have been addressed:
- CVE-2018-15767 – Improper Authorization Vulnerability
The Dell OpenManage Network Manager virtual appliance versions prior to 6.5.3 contain an improper authorization vulnerability caused by a misconfiguration in the /etc/sudoers file. A malicious OpenManage Network Manager user who has ‘synergy’ account privileges could potentially exploit this vulnerability to run arbitrary commands with root privileges on the affected system.
