Summary
adaguc-server GeoJSON coordinate parser (CConvertGeoJSON.cpp) vulnerable to out-of-bounds read and NULL pointer dereference
Details

Adaguc-server is an open source geographical information system to visualize, combine, compare and share real-time meteorological, climatological and remote sensing data via OGC standards. Versions prior to 7.2.2 crash with a memory-safety fault when it parses a GeoJSON document whose geometry contains a malformed coordinate. The coordinate parser in adagucserverEC/CConvertGeoJSON.cpp indexes pt.u.array.values[0] and pt.u.array.values[1] and uses polygon.u.array.length as a loop bound without first validating the JSON node type or the coordinate length. A coordinate that is an empty array, a one-element array, a scalar, or null leads to an out-of-bounds heap read or a NULL pointer dereference. The same unchecked pattern is present in four geometry branches: Polygon, LineString, MultiLineString and MultiPolygon. The vulnerable parser runs whenever the server processes a local GeoJSON file, either a configured GeoJSON dataset or a GeoJSON file exposed through the AutoResource feature and requested by an unauthenticated WMS request. A crafted GeoJSON file reliably crashes the backend process that handles that request. Version 7.2.2 patches the vulnerability.
