Symptom: A vulnerability in the Disk Check Tool (<i>disk-check.sh</i>) for Cisco Wide Area Application Services (WAAS) Software could allow an authenticated, local attacker to elevate their privilege level to <i>root</i>. The attacker must have valid user credentials with super user privileges (level 15) to log in to the device. The vulnerability is due to insufficient validation of script files executed in the context of the Disk Check Tool.
