A Deep Dive Into Attempted Exploitation of CVE-2023-33538

This report analyzes active scan-and-exploit activity targeting CVE-2023-33538 in end-of-life TP‑Link routers: researchers emulated TL-WR940N firmware, confirmed a command‑injection vulnerability via the ssid1 parameter (requiring authentication), analyzed Mirai-like arm7 malware and its C2/update behavior, observed noisy but flawed in-the-wild exploits (wrong parameter, unauthenticated, reliant on missing utilities), and published IOCs and mitigations.
