Technical details
HCL DFXAnalytics fails to set the 'secure' attribute on session cookies generated during the authentication process. This vulnerability, classified as CWE-200 (Exposure of Sensitive Information), occurs when the application does not instruct the browser to only transmit cookies over encrypted (HTTPS) channels. A remote attacker positioned to intercept network traffic (e.g., via a man-in-the-middle attack) could capture these cookies if a user's browser sends them over an unencrypted HTTP connection. The vulnerability affects version 3.0 and below; users should refer to HCL Software advisory KB0131787 for remediation steps.
