  • Cisco Wide Area Application Services (WAAS) Appliances

Known Affected Releases

6.2(3)

Description (partial)

Symptom:
A vulnerability in Cisco-provided scripts (disk-check.sh and harcap.sh) for Cisco Wide Area Application Services (WAAS) Software could allow an authenticated, local attacker to elevate their privilege level to root. 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 Cisco-provided scripts. An attacker could exploit this vulnerability by replacing one script file with a malicious script file while an affected Cisco-provided script is running. A successful exploit could allow the attacker to gain root-level privileges and take full control of the device.
