Description
HCL DFXAnalytics is affected by a Missing Secure Attribute in Encrypted Session (SSL) Cookie vulnerability. The application fails to set the "secure" attribute on session cookies generated during authentication, which could allow a remote attacker to intercept network traffic and capture sensitive cookies, session tokens, or credentials sent in cleartext over unencrypted channels.
