An attacker could exploit this vulnerability by entering crafted inputs to the web-based management interface of the affected software. A successful exploit could allow the attacker to execute arbitrary commands on the underlying operating system as the root user. \r\nCisco has assigned this vulnerability a SIR of High rather than Medium as the score indicates because additional security implications could occur when the attacker
