CVE-2020-35112

CVSS v2.0

9.3

High

VectorAV:N/AC:M/Au:N/C:C/I:C/A:C
Name of the Vulnerable Software and Affected Versions Firefox versions prior to 84 Thunderbird versions prior to 78.6 Firefox ESR versions prior to 78.6
Description The issue is related to insufficient access control in Mozilla browsers, allowing a remote attacker to execute arbitrary code or cause a denial of service. On Windows, if a user downloads a file without an extension and opens it from the downloads panel, an executable file with the same name but with an executable extension (such as .bat or .exe) in the downloads directory would be launched instead. This issue only affects Windows operating systems.
Recommendations For Firefox versions prior to 84, update to version 84 or later. For Thunderbird versions prior to 78.6, update to version 78.6 or later. For Firefox ESR versions prior to 78.6, update to version 78.6 or later.
