| Vector | AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H |
Name of the Vulnerable Software and Affected Versions
Mozilla Firefox versions prior to 111
Description
The issue is related to insufficient access control in Mozilla Firefox. Exploitation of this issue may allow a remote attacker to gain unauthorized access to protected information when a specially crafted document is opened. If temporary permissions, such as the ability to use the Camera, were granted to a document loaded using a file: URL, that permission persisted in that tab for all other documents loaded from a file: URL. This is potentially dangerous if the local files came from different sources, such as in a download directory.
Recommendations
For versions prior to 111, update to version 111 or later to resolve the issue. As a temporary workaround, consider restricting the use of file: URL loaded documents in the same tab to minimize the risk of exploitation. Avoid granting temporary permissions to documents from untrusted sources.
