Summary

HestiaCP Low-Privileged User to Root via Config-Field Injection and PATH Hijacking

Details

Hestia Control Panel is a lightweight and powerful control panel for the modern web. 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. When the user invokes the ordinary Search feature, the root-privileged v-search-user-object script loads the forged field through parse_object_kv_list_non_eval(), which permits reserved shell-variable names and globally replaces PATH before invoking column without an absolute path. By placing a malicious column executable in the injected search path, the user can execute arbitrary code as root. This residual vulnerability was introduced when version 1.9.7 replaced the raw eval sink addressed by CVE-2026-84984 with parse_object_kv_list_non_eval(), and it is fixed in version 1.10.5.
