CVE-2019-12170
ATutor through 2.2.4 is vulnerable to arbitrary file uploads via the mods/_core/backups/upload.php (aka backup) component.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (8.59%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
ATutor through 2.2.4 is vulnerable to arbitrary file uploads via the mods/_core/backups/upload.php (aka backup) component. This may result in remote command execution. An attacker can use the instructor account to fully compromise the system using a crafted backup ZIP archive. This will allow for PHP files to be written to the web root, and for code to execute on the remote server.
