Network access via default FAS key
Published Nov 17, 2023 · Updated Nov 26, 2024
Weak authentication in OpenNDS Captive Portal before 10.1.2 allows remote attackers to bypass the splash page and gain network access. In FAS mode, the portal accepts authentication protected by a publicly known default FAS key instead of a deployment-specific secret. Exploitation requires FAS configuration with the unchanged default key; success authenticates the client without completing the intended splash sequence.
