Summary

ASUS RT-BE57 router firmware from the 3.0.0.6_102 series is affected. A predictable seed in the pseudo-random number generator used for IFTTT pairing tokens (CWE-337) makes the tokens guessable. An unauthenticated nearby attacker can derive the pairing token from values observed during an administrator-initiated IFTTT pairing session and then read or modify router settings.

Description from the CNA

A predictable seed in the pseudo-random number generator (PRNG) in the IFTTT pairing token generation of the ASUS RT-BE57 router allows an unauthenticated nearby user to derive the pairing token and read or modify router settings via observed values from an administrator-initiated IFTTT pairing session.Refer to the ' Security Update for ASUS Router Firmware  ' section on the ASUS Security Advisory for more information.
