Nessus Plugin Scripts:

This repo is a collection of Python scripts designed to work with Nessus scan results. The scripts utilize the built-in xml.etree.ElementTree library to parse .nessus files and provide various functionalities such as counting findings, listing hosts/services for specific plugins, identifying services, merging Nessus files, and summarizing Scanner results.

istallation

With PIP:

pip install nessus-plugin-hosts

With Git:

git clone https://github.com/DefensiveOrigins/NessusPluginHosts
cd NessusPluginHosts

Tools Included

PyPI Command	Python Script	Description
nessus-finding-count	FindingCount.py	Counts findings from a Nessus file. Supports unique or total counts. Can analyze a single file or all .nessus files within a directory.
nessus-plugin-hosts	NessusPluginHosts.py	Lists hosts/services for a specific Nessus plugin. Supports multiple delimiter formats, can search a single file or many in a directory, and can export host:port lists.
nessus-identified-services	IdentifiedServices.py	Lists services identified within a Nessus file (e.g., plugin 22964).
nessus-merge	MergeNessus.py	Merges multiple Nessus files from a directory into a single .nessus file. Adjusts scan start/end times and allows changing the report title.
nessus-synscan-summary	SynScanSummary.py	Summarizes SYN Scanner results from plugin 11219. Outputs both hosts-per-port and ports-per-host analyses, with optional CSV output.
nessus-ldap-info	LDAPinfo.py	Parses LDAP-related information from plugins 20870 and 25701. Extracts LDAP services, info disclosure, domain names, and server names.
nessus-printer-info	PrinterInfo.py	Extracts printer information, including vendor/model (when identifiable) and open TCP ports.
nessus-remove-host	RemoveHost.py	Removes a specified host from a .nessus file.
nessus-host-info	HostInfo.py	Provides detailed information about a specific host, including scan timing, alternate hostnames, FQDNs, plugins triggered, and detected services.

🧰 Requirements

• Python 3.x

NessusPluginHosts.py / nessus-plugin-hosts (List Hosts/Services per Plugin)

# Default line-delimited
python NessusPluginHosts.py -f scan.nessus 19506

# Default line-delimited, no port
python NessusPluginHosts.pyy -f scan.nessus 19506 --no-port

# Space-delimited
python NessusPluginHosts.py -f scan.nessus 19506 --space-delim

# Space-delimited, no-port -- Specfication for metasploit "rhosts"
python NessusPluginHosts.py -f scan.nessus 19506 --space-delim --no-port

# Comma-delimited
python NessusPluginHosts.py -f scan.nessus 19506 --comma-delim

# Comma-delimited, no port
python NessusPluginHosts.py -f scan.nessus 19506 --comma-delim --no-port

# List High severity (0 = Info, 1 = Low, 2 = Med, 3 = High, 4 = Critical) finding names in terminal
python NessusPluginHosts.py -f scan.nessus --list-plugins 3

# List ALL severity finding names in terminal
python NessusPluginHosts.py -f scan.nessus --list-plugins

# Export ALL findings to nessus_plugin_hosts directory, create file for each finding with an ordered host:port list
python NessusPluginHosts.py -f scan.nessus --list-plugins --export-plugin-hosts ./nessus_plugin_hosts

IdentifiedServices.py / nessus-identified-services (List Identified Services)

Looks at the Nessus plugin 22964 and outputs the services by service type.

python IdentifiedServices.py scan.nessus --no-port --comma-delim

MergeNessus.py /nessus-merge (Merge Nessus Files)

# Merges all nessus files in current folder, outputs to "Merged.Nesssus"
python3 MergeNessus.py

# Merge all nessus files in specific directory
python3 MergeNessus.py -d /path/to/nessus/files

# Merge and set custom filename
python3 MergeNessus.py -o /path/to/output/Combined_Scan.nessus

# Merge and give the merged scan a custom title:
python3 MergeNessus.py -t "Quarterly Security Scan"

# Merge from a directory, set both custom title and output file:
python3 MergeNessus.py -d /scans/q1 -o ./Merged_Q1.nessus -t "Q1 Combined Scan"

HostInfo.py / nessus-host-info (Provide Host Details)

Provides details about a host, alternate hostnames, scanning times, etc.

python3 HostInfo.py -f input.nessus -n 192.168.1.1

python3 HostInfo.py -d ./nessusDirectory/ -n 192.168.1.1

RemoveHost.py / nessus-remove-host (Remove Host from Nessus File)

python3 RemoveHost.py -f input.nessus -o output.nessus -n target-hostname

SynScanSummary.py / nessus-synscan-summarySummary

Reads Nessus results from Nessus' Plugin 11219 (SYN Scanner) and creates an output summarizing the scan results.

Usage

# Show both summaries to stdout
python .\SynScanSummary.py .\scan.nessus

# Only ports per host, showing at most 15 ports per host
python .\SynScanSummary.py .\scan.nessus --analysis ports-per-host --limit 15

# Only hosts per port, for a specific port set, to stdout
python .\SynScanSummary.py .\scan.nessus --analysis hosts-per-port --include-ports 22,80,443,8000-8100

# Write CSV (and also print to stdout)
python .\SynScanSummary.py .\scan.nessus --csv .\syn_summary.csv

# Write CSVs only (no stdout), both analyses -> creates syn_summary_ports_per_host.csv and syn_summary_hosts_per_port.csv
python .\SynScanSummary.py .\scan.nessus --analysis both --csv .\syn_summary.csv --no-stdout

Example

SynScanSummary.py Merged.nessus --analysis hosts-per-port

SynScanSummary.py Merged.nessus --analysis ports-per-host

LDAPinfo.py / nessus-ldap-info (LDAP Information Gathering)

This script parses the details from plugins 20870 and 25701 and returns the information in a easy to read format. No more hunting the Nessus file when you just quickly need the LDAP information.

Usage

# Parse a single Nessus file 
python3 LDAPinfo.py -f scan.nessus

# Parse all Nessus files in a directory
python3 LDAPinfo.py -d /path/to/nessus/files

# Output to a specific CSV file (for paste into Excel/word)
python3 LDAPinfo.py -f scan.nessus --csv /tmp/ldap_info.csv

Example Output

# $ python3 LDAPinfo.py -d /path/to/nessus/files
