CVE-2021-41919 · HIGH Severity

CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H

webTareas version 2.4 and earlier allows an authenticated user to arbitrarily upload potentially dangerous files without restrictions. This is working by adding or replacing a personal profile picture. The affected endpoint is /includes/upload.php on the HTTP POST data. This allows an attacker to exploit the platform by injecting code or malware and, under certain conditions, to execute code on remote user browsers.
