CVE-2020-3547    

CWE-200

Summary

  o A vulnerability in the web-based management interface of Cisco AsyncOS
    software for Cisco Content Security Management Appliance (SMA) and Cisco
    Web Security Appliance (WSA) could allow an authenticated, remote attacker
    to access sensitive information on an affected device.

    The vulnerability exists because an insecure method is used to mask certain
    passwords on the web-based management interface. An attacker could exploit
    this vulnerability by looking at the raw HTML code that is received from
    the interface. A successful exploit could allow the attacker to obtain some
    of the passwords configured throughout the interface.

    There are no workarounds that address this vulnerability.
