"According to its self-reported version number, the version of SolarWinds Orion Platform is prior to 2020.2.6 HF1. It is,
therefore, affected by multiple vulnerabilities:

  - A command injection vulnerability in the EmailWebPage API. An authenticated,
    remote attacker can exploit this to execute arbitrary
    commands.(CVE-2021-35220)
  
  - An arbitrary file read vulnerability in ExportToPdfCmd. An authenticated,
    remote attacker can exploit this to read arbitrary files and disclose
    sensitive information. (CVE-2021-35219)
  
  - An improper access control tampering vulnerability. An authenticated, remote
    attacker can exploit this to add arbitrary SMTP servers to the server
    configuration. (CVE-2021-35221)
  
  - Multiple stored cross-site scripting vulnerabilities. A cross-site scripting
    (XSS) vulnerability exists due to improper validation of user-supplied input
    before returning it to users. An unauthenticated, remote attacker can exploit
    this, by convincing a user visit a URL, to execute arbitrary script code in a
    user's browser session. (CVE-2021-35238, CVE-2021-35239, CVE-2021-35240)
  
  - A reflected cross-site scripting vulnerability. A cross-site scripting (XSS)
    vulnerability exists 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-2021-35222)

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