What an attacker can do

The source says from version 1.9.7 through 1.10.4, update_object_value() in func/main.sh does not escape single quotes when writing a custom document-root value to a user's web.conf file, allowing a low-privileged authenticated panel user with a web domain to inject an additional PATH field. Vendor/CNA’s CVSS 3.1 assessment (base score 9.9/10) rates confidentiality, integrity and availability impact as high.
