Description

CentreStack before 17.4 contains a SQL injection vulnerability in GladDBFiles.SearchEx() and SearchExUnder() that allows authenticated attackers to execute arbitrary SQL statements by supplying a crafted x-glad-filter request header through the jsondir API endpoint. Attackers can exploit unsanitized interpolation of the Field parameter directly into SQL query strings to write arbitrary files to the server filesystem via PostgreSQL lo_from_bytea() and lo_export() functions, enabling remote code execution.
