RHEL 8 : firefox (Unpatched Vulnerability)

medium Nessus Plugin ID 195490

Synopsis

The remote Red Hat 8 host is affected by multiple vulnerabilities that will not be patched.

Description

The remote Redhat Enterprise Linux 8 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

 - firefox: mixed content warning is not displayed when HTTPS page loads a favicon over HTTP (CVE-2018-12403)

 - firefox: WebExtensions can load arbitrary URLs through pipe separators (CVE-2018-18497)

 - By using the reflected URL in some special resource URIs, such as chrome:, it is possible to inject stylesheets and bypass Content Security Policy (CSP). This vulnerability affects Firefox < 63.
 (CVE-2018-12398)

 - When a new protocol handler is registered, the API accepts a title argument which can be used to mislead users about which domain is registering the new protocol. This may result in the user approving a protocol handler that they otherwise would not have. This vulnerability affects Firefox < 63. (CVE-2018-12399)

 - Some special resource URIs will cause a non-exploitable crash if loaded with optional parameters following a '?' in the parsed string. This could lead to denial of service (DOS) attacks. This vulnerability affects Firefox < 63. (CVE-2018-12401)

 - 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)

 - WebExtension content scripts can be loaded into about: pages in some circumstances, in violation of the permissions granted to extensions. This could allow an extension to interfere with the loading and usage of these pages and use capabilities that were intended to be restricted from extensions. This vulnerability affects Firefox < 64. (CVE-2018-18495)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

Solution

The vendor has acknowledged the vulnerabilities but no solution has been provided. Refer to the vendor for remediation guidance.
