"The version of Adobe Connect running on the remote host is 11.2.2 or earlier. It is, therefore, affected by multiple 
vulnerabilities. 

  - An unsafe deserialization vulnerability exists in Adobe Connect. An unauthenticated, remote attacker can exploit 
    this to execute arbitrary code on the target host. (CVE-2021-40719)

  - A reflected cross-site scripting (XSS) vulnerability exists in Adobe Connect due to improper validation of 
    user-supplied input before returning it to users. An unauthenticated, remote attacker can exploit this, by 
    convincing a user to click a specially crafted URL, to execute arbitrary script code in a user's browser session.
    (CVE-2021-40721)

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