Administrator password disclosure via plaintext HTML embedding

Published Dec 4, 2025 · Updated Dec 5, 2025

Credential disclosure in Waveshare RS232/485 TO WIFI ETH (B) firmware 3.1.1.0 allows remote authenticated users to read the administrator password. The web management page returns the SYSPS value in an HTML text input, embedding the credential in plaintext where the page and DOM expose it. Low-privilege access to the management interface is sufficient to recover the credential and obtain administrative control.
