CVE-2018-1340 : What You Need to Know

Apache Guacamole 0.9.4 to 0.9.14 utilized a cookie without the 'secure' flag, potentially exposing user session tokens to attackers.

Understanding CVE-2018-1340

Apache Guacamole's vulnerability stemmed from insecure cookie handling, allowing interception of session tokens.

What is CVE-2018-1340?

Prior to version 1.0.0, Apache Guacamole stored session tokens in cookies without the 'secure' attribute, enabling network eavesdropping attacks.

The Impact of CVE-2018-1340

The absence of the 'secure' flag in Apache Guacamole's cookies could lead to session token theft by malicious actors monitoring network traffic.

Technical Details of CVE-2018-1340

Apache Guacamole's vulnerability lies in its cookie management and lack of secure attribute implementation.
