Linux Distros Unpatched Vulnerability : CVE-2018-1340

high Nessus Plugin ID 260852

Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

- Prior to 1.0.0, Apache Guacamole used a cookie for client-side storage of the user's session token. This cookie lacked the secure flag, which could allow an attacker eavesdropping on the network to intercept the user's session token if unencrypted HTTP requests are made to the same domain. (CVE-2018-1340)

Note that Nessus relies on the presence of the package as reported by the vendor.

Solution

There is no known solution at this time.
