A Use of Client-Side Authentication issue was discovered in Advantech B+B SmartWorx MESR901 firmware versions 1.5.2 and prior. The web interface uses JavaScript to check client authentication and redirect unauthorized users. Attackers may intercept requests and bypass authentication to access restricted web pages.
A client/server product performs authentication within client code but not in server code, allowing server-side authentication to be bypassed via a modified client that omits the authentication check.
