"According to its version, the ConnectWise ScreenConnect Service remote access software installed on the remote
Windows host is prior to 23.9.8. It is, therefore affected by multiple vulnerabilities:

  - A path-traversal vulnerability which may allow an attacker the ability to execute remote code or directly impact
    confidential data or critical systems. (CVE-2024-1708)

  - An Authentication Bypass Using an Alternate Path or Channel vulnerability which may allow an attacker direct
    access to confidential information or critical systems. (CVE-2024-1709)

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