The exploit chains two flaws: a firmware upload endpoint that performs its authentication check after writing the file to disk (and never cleans up on failure), and a SOAP endpoint whose authentication logic uses inconsistent comparison operators — a substring match for allowlisted paths but an exact match for the denylisted path — allowing bypass by appending an allowlisted string as a query parameter. An attacker can upload a malicious unsigned firmware image and trigger flashing without any credentials, either from the LAN or remotely if remote management is enabled. Shodan shows at least 41 exposed devices. The router is end-of-life, its OTA update infrastructure is defunct, and Motorola's two divisions each disclaimed responsibility, leading to full public disclosure with no patch available. ## Full article daily.dev links to this article rather than hosting it.
