vulnerability as referenced in the apsb21-76 advisory.

  - Adobe Creative Cloud Desktop Application version 5.4 (and earlier) is affected by a file handling
    vulnerability that could allow an attacker to arbitrarily overwrite a file. Exploitation of this issue
    requires local access, administrator privileges and user interaction. (CVE-2021-28613)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
