AI-suggested
Since the vulnerability involves use of unencrypted WebSocket connections, the recommended mitigation is to configure the affected WebSocket connection to use the secure wss:// protocol to ensure encryption of data in transit. Monitor vendor advisories for any official fixes or updates.
Description
HCL AION contains a vulnerability where a second WebSocket connection in the GenAI web interface uses an unencrypted ws:// protocol instead of the secure wss:// protocol. This missing encryption can allow network attackers to intercept or read data transmitted over this connection. The vulnerability is classified as CWE-311 and has a low severity with a CVSS score of 3.7.
