CVE-2025-1629

OTP guessing via unrestricted authentication attempts

Published Feb 24, 2025 · Updated Feb 24, 2025

Improper authentication-attempt limiting in my Excitel 3.13.0 for Android allows remote authenticated users to make excessive OTP guesses. An undisclosed function in the One-Time Password Handler fails to restrict repeated authentication attempts; no finer-grained implementation details are public. Reachability requires low-privileged access from an adjacent network, and the published impact is limited to confidentiality loss.
