SonicWall SMA100 Appliances OS Command Injection Vulnerability
SonicWall · SMA100 Appliances
A command injection flaw in the SSL-VPN management interface of SonicWall SMA100 Appliances arises from improper neutralization of special elements in input handling. An attacker with remote network access and administrative privileges on the appliance, requiring no user interaction, can inject arbitrary OS commands that run as the 'nobody' user.
Improper neutralization of special elements in the SMA100 SSL-VPN management interface allows a remote authenticated attacker with administrative privilege to inject arbitrary commands as a 'nobody' user, potentially leading to OS Command Injection Vulnerability.
