CVE-2023-42179Public exploit

Credential recovery via truncated Argon2I password input

Published Aug 26, 2026 · Updated Aug 26, 2026

Incorrect access control in Bird Home Automation D1101V-F firmware 000140 allows attackers to recover credentials via captured local broadcasts. The broadcast cryptogram's Argon2I key derivation uses only the first five password characters, reducing the effective secret to about 30 bits and enabling offline brute force. An attacker must join the device's local network and capture a valid encrypted datagram; unrestricted login guesses for the remaining characters grant user commands, including control of a configured door opener.
