ASDM Version Scanner

The ASDM Version Scanner will load a CSV of IP addresses and ports and attempt to connect to /admin/public/index.html via HTTPS. Once successfully connected, the script will then attempt to extract the ASDM version number from the page's <title>. I use the script like so:

Step 1: Download potential targets from Shodan

shodan download --limit -1 title_cisco_asdm title:"Cisco\ ASDM"
shodan download --limit -1 default_ssl ssl:"ASA\ Temporary\ Self\ Signed\ Certificate"
shodan download --limit -1 webvpn_cookie "Set-Cookie: webvpn_portal"

Step 2: Extract the IP and ports into csv files

shodan parse --fields ip_str,port --separator , title_cisco_asdm.json.gz > title.csv
shodan parse --fields ip_str,port --separator , default_ssl.json.gz > default.csv
shodan parse --fields ip_str,port --separator , webvpn_cookie.json.gz > webvpn.csv

Step 3: Remove duplicates

cat title.csv > all.csv
cat default.csv >> all.csv
cat webvpn.csv >> all.csv
cat all.csv | sort | uniq > all_uniq.csv
wc -l all_uniq.csv
$ 212874 all_uniq.csv

Step 4: Begin scanning

python3 asdm_version_scanner.py --csv ./data/06152022.csv > ./output/06152022.txt

Step 5: Sort and count the collected data

cat 06152022.txt | grep -oP 'Cisco ASDM \d\.\d.*$' | sort | uniq -c | sort -nr
