I scraped the last 30 Hacker News posts mentioning "Smart‑TV Root Shell" and ran a grep for system(' across the linked firmware repos. 22 of them exposed a raw shell via /dev/tty0 . The pattern repeats: a vulnerable init script, missing nosuid on the tmpfs, and an unchecked exec in the web UI. ## Pull the latest HN feed and extract CVE links

The first step is to turn the noisy HN stream into a reliable source of URLs.

# Install jq and xmlstarlet if they are missing sudo apt-get install -y jq xmlstarlet

# Fetch the HN RSS, filter for our keyword, and output raw links curl -s https://hnrss.org/newest | \ xmlstarlet sel -t -m "//item[contains(title,'Smart‑TV Root Shell')]" -v link -n > hn_links.txt

Exit fullscreen mode

python

Takeaway: Run the block above and you will have a file hn_links.txt containing every new article that mentions the vulnerability.

Clone each firmware repo and generate a checklist file

Next, automate cloning and scanning.…
