CVE-2021-22798Network attack vector

Credential disclosure via unencrypted HTTP login

Published Feb 11, 2022 · Updated Aug 3, 2024

Insufficiently protected credentials in Conext ComBox all versions allow attackers to read login credentials through network sniffing. The appliance exposes its HTTP web login on port 80 and carries the exchange as unencrypted network traffic rather than through a protected transport. Attackers must observe the network path, and the published consequence is limited to disclosure of sensitive data such as login credentials.
