Technical details

An external control of file name/path (CWE-22) and improper neutralization of special elements (CWE-74) in the GUI processing allow authenticated administrators to bypass pathname restrictions and inject special characters. The vulnerability is triggered via specially crafted requests to the web interface; no further user interaction or network-level attack vector is required. An attacker with admin credentials gains code execution and arbitrary file read/write capability on the appliance.
