"The version of Adobe Connect running on the remote host is 11.0.5 or earlier. It is, therefore, affected by multiple 
vulnerabilities, including the following:

  - Multiple reflected cross-site scripting vulnerabilities due to improper validation of user-supplied input
    before returning it to users. An remote attacker can exploit these, by convincing a user to click a
    specially crafted URL, to execute arbitrary script code in a user's browser session. (CVE-2021-21079,
    CVE-2021-21080, CVE-2021-21081)

  - An arbitrary code execution vulnerability due to improper input validation. (CVE-2021-21085)


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