| Vector | AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:N |
Name of the Vulnerable Software and Affected Versions
Firefox versions prior to 117
Firefox ESR versions prior to 115.4
Thunderbird versions prior to 115.4.1
Description
The issue is related to errors in the representation of information in the user interface, allowing an attacker to conduct spoofing attacks using a specially crafted link. This can be achieved by creating a malicious link using bidirectional characters to spoof the location in the address bar when visited.
Recommendations
For Firefox versions prior to 117, update to version 117 or later to resolve the issue.
For Firefox ESR versions prior to 115.4, update to version 115.4 or later to resolve the issue.
For Thunderbird versions prior to 115.4.1, update to version 115.4.1 or later to resolve the issue.
As a temporary workaround, consider avoiding the use of bidirectional characters in links until a patch is available.
