A vulnerability in the backend Packet Capture Utility of the Cisco Web Security Appliance (WSA) could allow an authenticated, local attacker to
modify contents within certain files.

The vulnerability is due to insufficient write restrictions of output files to a safe directory. An attacker could exploit this vulnerability by

write to any file.
