Detailed vulnerability description
The vulnerability allows a remote user to execute arbitrary code.
The vulnerability exists due to command injection in backup functionality in interface/main/backup.php when processing user-supplied backup selection values embedded in shell commands. A remote privileged user can send specially crafted backup parameters referencing attacker-controlled database values to execute arbitrary code.
Exploitation requires access to the backup functionality and the ability to place a payload in database fields such as list_options.option_id, list_options.list_id, layout_options.form_id, or layout_group_properties.grp_form_id.
