"The version of ArcGIS Server installed on the remote host is 12.0 or prior. It is, therefore, affected by multiple
vulnerabilities:

  - ArcGIS Server contains a directory traversal vulnerability. An unauthenticated attacker could exploit this issue
    by sending crafted path parameters. Successful exploitation could allow access to sensitive files on the system.
    (CVE-2026-9181)

  - ArcGIS Server contains an unrestricted file upload vulnerability. An unauthenticated attacker could exploit this
    issue by uploading a crafted file to the affected endpoint. Successful exploitation could allow arbitrary file
    upload. (CVE-2026-9182)

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