漏洞描述
GeoServer is an open source software server written in Java that allows users to share and edit geospatial data. GeoTools FilterToSqlHelper.constructEquality writes the expected argument of the jsonArrayContains CQL function RAW into the SQL string while only escaping the JSON pointer. A single quote in the value parameter breaks out of the PostgreSQL jsonb_path_exists string literal, enabling unauthenticated SQL injection. When the PostGIS backend runs with superuser privileges, the injection escalates to operating system command execution through PostgreSQL COPY TO PROGRAM. Users are advised to upgrade to either version 2.21.4, or version 2.22.2 to resolve this issue. Users unable to upgrade should enable the PostGIS DataStore preparedStatements setting and disable encode functions as a workaround.
