| Vetor | AV:N/AC:L/Au:N/C:C/I:C/A:C |
Name of the Vulnerable Software and Affected Versions
Mozilla Firefox versions prior to 56
Description
The issue is related to insufficient permission checks for a critical resource in the WebExtensions module of Mozilla Firefox. This could allow a remote attacker to elevate their privileges. Additionally, WebExtensions can download and attempt to open certain non-executable file types without specific user interaction, potentially triggering known vulnerabilities in programs that handle those document types.
Recommendations
For versions prior to 56, update to a version that contains a fix for this issue to prevent potential exploitation. As a temporary workaround, consider restricting the use of WebExtensions to minimize the risk of exploitation. Avoid using WebExtensions to download and open files of non-executable types until the issue is resolved.
