"The version of Adobe Creative Cloud Desktop installed on the remote host is prior to version 5.4. It is, therefore,
affected by multiple vulnerabilities, including the following:

  - An arbitrary file write vulnerability that leads to arbitrary code execution. (CVE-2021-21068)

  - An OS command injection vulnerability that leads to arbitrary code execution. (CVE-2021-21078)

  - Improper input validation that can allow an attacker to elevate their privileges. (CVE-2021-21069)

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