An authenticated administrator of the SMA1000 Appliance Management Console can inject malicious operating system commands through the application, allowing them to execute arbitrary code on the server. This is dangerous because it gives attackers complete control over the affected system.
Post-authentication OS command injection vulnerability in SMA1000 AMC allows an authenticated administrator to execute arbitrary OS commands via improper neutralization of special elements in command inputs. Attack vector requires valid admin credentials and specific conditions; successful exploitation results in remote code execution with system-level privileges.
In the same product, most dangerous first.
