| Vetor | AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N |
Name of the Vulnerable Software and Affected Versions
Firefox versions prior to 57
Description
The issue is related to the display of Punycode format text for entire qualified international domain names in certain instances. When a sub-domain triggers the Punycode display, it can cause user confusion, potentially leading to limited spoofing attacks. The vulnerability is associated with an insufficient input validation mechanism in the Punycode conversion method implementation.
Recommendations
For versions prior to 57, update to version 57 or later to resolve the issue. As a temporary workaround, consider being cautious when encountering international domain names with sub-domains to minimize the risk of exploitation.
