Nmap script that provides information about probable vulnerabilities based on discovered services.
Contents:
The current implementation take care of the following cases:
-
If Nmap detects:
cpeANDversion: vulnerabilities affectingversionand vulnerabilities affecting a range of versions that includeversion.cpeANDversion range: vulnerabilities affecting versions betweenversion range(included).cpebut NOversion: vulnerabilities that affect every version of the product.- If no vulnerabilities were found with
cpeandversionreturned from Nmap, HTTP detection is used. - NO
cpe: HTTP detection is used.
-
HTTP detection:
- Used only if port matches HTTP/SSL/UPnP.
- An HTTP GET request is sent for every combination of path
and extension in
extra/http-paths-vulnerscom.json, comparing the request headers/body with the regexes inextra/http-regex-vulnerscom.json. - Finally, the home page html is analyzed in search for library paths. The script tries to obtain the name and version from library location; then does an HTTP GET to that path in order to inspect the code of the library and analyze the starting commenot looking for the version.
Nmap library shortport is used to detect if port matches HTTP/SSL.
In order to run cvescannerv2 script, you need the following files present in your working directory
- CVE database:
cve.db - Paths file:
extra/http-paths-vulnerscom.json - Regex file:
extra/http-regex-vulnerscom.json - Product-aliases file:
extra/product-aliases.json
In addition, you must have installed lua-sql-sqlite3 (ubuntu)
or lua5.4-sql-sqlite3 (alpine) packages
If you don't have the database cve.db, you can build it
using the script extra/database.py or download a (semiupdated) copy
from CVEScannerV2DB using .sql files
or under Actions->Latest->Summary->Artifacts
This repository is updated every two weeks
pip install -r extra/requirements.txt
python extra/database.pygit clone https://github.com/scmanjarrez/CVEScannerV2DB
cd CVEScannerV2DB && sh build.shNote: In order to execute
extra/database.py, you need to request an API key and save it to a file named.apion your current working directory or in the environment variableNVD_KEY.
To run the script, use the following syntax
nmap -sV --script cvescannerv2 <TARGET>
nmap -sV --script cvescannerv2 --script-args log=logfile.log,json=logfile.json <TARGET>
It is possible to modify the behaviour to some extent using the following arguments: db, maxcve, http, maxredirect, log, json, path, regex, aliases, service and version.
script-args default values
db: cve.db
maxcve: 10
http: 1
maxredirect: 1
log: cvescannerv2.log
json: cvescannerv2.json
path: extra/http-paths-vulnerscom.json
regex: extra/http-regex-vulnerscom.json
aliases: extra/product-aliases.json
service: all
version: all
script-args examples
nmap -sV --script cvescannerv2 --script-args db=cve.db <TARGET>
nmap -sV --script cvescannerv2 --script-args maxcve=5 <TARGET>
# Change reports path
nmap -sV --script cvescannerv2 --script-args log=scan2023.log,json=scan2023.json <TARGET>
# Only scan certain service/version
nmap -sV --script cvescannerv2 --script-args service=http_server,version=2.4.57 <TARGET>
# Disable HTTP detection
nmap -sV --script cvescannerv2 --script-args http=0 <TARGET>
Note:
cvescannerv2.nsecan be placed in Nmap default script directory for global execution.
Linux and OSX default script locations:
- /usr/local/share/nmap/scripts/
- /usr/share/nmap/scripts/
- /opt/local/share/nmap/scripts/
- /usr/local/Cellar/nmap/<version>/share/nmap/scripts/
Windows default script locations:
- C:\Program Files\Nmap\Scripts
- %APPDATA%\nmap
It's recommended to create a symbolic link, so changes in repository are reflected in the script.
CVEScannerV2 will show CVEs related to every service-version discovered.
Note: This script depends on heuristics implemented in Nmap, so if it doesn't detect a service or is detected incorrectly, CVEScannerV2 will show an incorrect output.

Fix: Install the library based on your OS (check Requirements) and create a symlink to Nmap search path.
apt install lua-sql-sqlite3
ln -s /usr/lib/x86_64-linux-gnu/lua /usr/local/lib/luaapk add --no-cache lua5.4-sql-sqlite3
ln -s /usr/lib/lua /usr/local/lib/luaAbove commands may require super user permissions.
