CVSS v2.0
5.0
Média
| Vetor | AV:N/AC:L/Au:N/C:P/I:N/A:N |
Name of the Vulnerable Software and Affected Versions
Mozilla Firefox versions prior to 43.0
Description
The issue is related to the importScripts function in the Web Workers API implementation, which lacks protection of internal data. This can be exploited by a remote attacker to bypass the existing access restriction policy, leading to information disclosure. The exploitation involves triggering the use of the no-cors mode in the fetch API to attempt resource access that throws an exception.
Recommendations
For versions prior to 43.0, update to version 43.0 or later to resolve the issue. As a temporary workaround, consider restricting access to the importScripts function until a patch is available. Avoid using the no-cors mode in the fetch API for sensitive resource access until the issue is resolved.
