CVE-2020-6797
CVSS v3.1
4.3
Medium
| Vector | AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N |
Name of the Vulnerable Software and Affected Versions
Thunderbird versions prior to 68.5
Firefox versions prior to 73
Firefox ESR versions prior to 68.5
Description
A semi-privileged extension can launch an arbitrary application on the user's computer by downloading a file with the .fileloc extension. However, the attacker's ability to exploit this issue is limited as they cannot download non-quarantined files or supply command line arguments to the application. This issue only affects Mac OSX, with other operating systems being unaffected.
Recommendations
For Thunderbird versions prior to 68.5, update to version 68.5 or later.
For Firefox versions prior to 73, update to version 73 or later.
For Firefox ESR versions prior to 68.5, update to version 68.5 or later.
As a temporary workaround, consider restricting the handling of .fileloc files to minimize the risk of exploitation.
Fix
