The research covers: (1) fleet-wide RSA private keys embedded in SPI flash, identical across all devices; (2) unsalted MD5 hashing of TP-Link ID credentials stored in plaintext email alongside the hash, enabling cross-platform account takeover; and (3) unauthenticated GPS coordinate exposure via a single UDP packet to port 9999 — a protocol flaw publicly known since 2016 and documented on other TP-Link cameras since 2020. A secondary market attack chain is confirmed: a secondhand device exposes the previous owner's home GPS coordinates and recoverable credentials without any network access to the victim. The disclosure timeline spans six months, including a triage failure by the vendor, a bricked test device from a beta OTA, and disagreements over CVSS scoring. The advisory also documents four additional findings closed by the vendor as accepted risk, including a failsafe authentication bypass and hardcoded staging endpoints in production firmware. ## Full article daily.dev links to this article rather than hosting it.
