CVE-2020-12393
CVSS v3.1
7.8
High
| Vector | AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H |
Name of the Vulnerable Software and Affected Versions
Firefox ESR versions prior to 68.8
Firefox versions prior to 76
Thunderbird versions prior to 68.8.0
Description
The 'Copy as cURL' feature of Devtools' network tab did not properly escape the HTTP method of a request, which can be controlled by the website. If a user used the 'Copy as cURL' feature and pasted the command into a terminal, it could have resulted in command injection and arbitrary command execution. This issue only affects Firefox on Windows operating systems.
Recommendations
For Firefox ESR versions prior to 68.8, update to version 68.8 or later.
For Firefox versions prior to 76, update to version 76 or later.
For Thunderbird versions prior to 68.8.0, update to version 68.8.0 or later.
As a temporary workaround, consider avoiding the use of the 'Copy as cURL' feature in the Devtools' network tab until a patch is applied.
