Linux Distros Unpatched Vulnerability : CVE-2018-12402

medium Nessus Plugin ID 222022

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.

- The internal WebBrowserPersist code does not use correct origin context for a resource being saved. This manifests when sub-resources are loaded as part of Save Page As... functionality. For example, a malicious page could recover a visitor's Windows username and NTLM hash by including resources otherwise unreachable to the malicious page, if they can convince the visitor to save the complete web page.
Similarly, SameSite cookies are sent on cross-origin requests when the Save Page As... menu item is selected to save a page, which can result in saving the wrong version of resources based on those cookies.
This vulnerability affects Firefox < 63. (CVE-2018-12402)

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

Solution

There is no known solution at this time.
