CVE-2023-53968Public exploitNetwork attack vector

Account deletion via IP-bound session reuse

Published Dec 22, 2025 · Updated Dec 22, 2025

Authentication bypass in DB Broadcast SFT DAB 600/C firmware 1.9.3 allows remote attackers to delete user accounts through its web API. The management interface binds a Session ID to the client IP, so userManager accepts destructive requests from an attacker reusing an IP with an established session. Reachability requires an active victim session and the same apparent source address, such as behind shared NAT; successful requests remove accounts.
