RDP Scanner

This Python script performs an RDP (Remote Desktop Protocol) scan on a specified IP address and port. The script utilizes the nmap tool to run two NSE (Nmap Scripting Engine) scripts: rdp-ntlm-info and rdp-enum-encryption. It then extracts relevant information, including NTLM details, and builds a Common Platform Enumeration (CPE) string. The results are saved to an output file.

##Prerequisites Ensure that nmap is installed on your system.

Usage

python rdp_extractor.py <ip_address> <port> <output_file>

Example Output

(env) alessandro@xps:~/Development/rdp$ python rdp_extractor.py 207.81.231.54 3389 rep
RDP-NTLM-Info scan successful. Results saved to rep
RDP-Enum-Encryption scan successful. Results appended to rep

Script Components

  1. parse_ntlm_info(output) Parses the output of the rdp-ntlm-info script using regular expressions. Extracts information such as Target Name, NetBIOS Domain Name, NetBIOS Computer Name, DNS Domain Name, DNS Computer Name, DNS Tree Name, and Product Version.

  2. build_cpe(ntlm_info) Builds a CPE string based on the extracted NTLM information. Uses the vendor "Microsoft," product "Windows," and the product version (if available).

  3. get_screenshot() [To be implemented] Function to capture an RDP screenshot.

  4. scan_rdp(ip_address, port, output_file) Runs the rdp-ntlm-info script using nmap. Parses NTLM information and builds a CPE string. Saves the results to the specified output file. [Optional] Runs the rdp-enum-encryption script and appends the results to the same output file

CVE helper script

With the informations gathered byt the above script is possible to easily figure out the CPE of the relative system eg: cpe:2.3:a:microsoft:windows:10.0.17763 is cpe:2.3:o:microsoft:windows_10:1809 > this is how I figured out to query the NVD database of CVEs see - https://nvd.nist.gov/products/cpe/detail/1EFCEE85-EB7B-4D97-8675-57A3A5DA72DE?namingFormat=2.3&orderBy=CPEURI&keyword=cpe%3A2.3%3Ao%3Amicrosoft%3Awindows_10_1809&status=FINAL%2CDEPRECATED
