CVE-2024-0556Network attack vector

Credential disclosure via reversible Base64 encoding

Published Jan 16, 2024 · Updated Nov 13, 2024

Weak password encoding in Xantech WIC1200 Firmware 1.1 allows remote authenticated users to recover intercepted credentials. The firmware transmits credential values protected only by reversible Base64 encoding, so captured traffic yields readable usernames and passwords. Network access and valid low-privilege credentials are required; interception discloses another user's plaintext credentials without interrupting service.
