Nessus File Format Change?

[LarryLambert]

Running in debug, here is the error we get:

PS C:\inetpub\scans> C:\Scripts\Nessus_Schedule.ps1 DEBUG: NessusFilePath: \ZZZ\nessus\6923.nessus DEBUG: CustomerName: ZZZ DEBUG: Current Dir: C:\inetpub\scans DEBUG: TemplatePath: C:\Scripts\vcr-master\template-networkscan DEBUG: NewFolderPath: C:\inetpub\scans\ZZZ-20191231021514 [] Performing PreReq Checks...

Line 935 of the script:

#region NESSUS FILE PARSING

function Update-UniqueVulns($vulnname, $criticality) { if ($vulnnames.ContainsKey($vulnname) -eq $false) { $script:vulnnames.Add($vulnname, $criticality) Write-Debug "Update-UniqueVulns: Added uniqe vulnn to $ vulnnames: $vulnname" } }

Something in the format of the Nessus file changed so $vulnname variable is returning null.
