pgpartman pg_partman

pg_partman is a PostgreSQL extension that manages partitioned tables by time or ID. Prior to 5.5.0, drop_partition_id() and drop_partition_time() use part_config.retention_schema as the target for ALTER TABLE SET SCHEMA and accept any nonempty schema name. A role with partman_user access can select a target schema where the role lacks the normal CREATE privilege, and the background worker performs the relocation with pg_partman_bgw.role privileges, which default to PostgreSQL superuser, bypassing the authorization check that a normal ALTER TABLE SET SCHEMA operation would enforce. This permits unauthorized relocation of retained child tables between schemas. This issue is fixed in version 5.5.0.

pgpartman pg_partman

pg_partman is a PostgreSQL extension that manages partitioned tables by time or ID. Prior to 5.5.0, undo_partition() reads part_config.time_encoder as unrestricted text and interpolates it without identifier quoting into a dynamically executed SELECT statement. A role with partman_user access can store SQL rather than a function name, and the SQL executes with the privileges of the caller that invokes undo_partition(). The function is not part of the default background-worker path, which limits the automatic superuser escalation described by the related create-partition vulnerability, but a privileged caller can still have its available confidentiality, integrity, and availability permissions abused. This issue is fixed in version 5.5.0.

pgpartman pg_partman

pg_partman is a PostgreSQL extension that manages partitioned tables by time or ID. Prior to 5.5.0, run_maintenance(), show_partitions(), show_partition_info(), undo_partition(), and partition_data_time() interpolate the writable part_config.time_dncoder text value without identifier quoting into dynamic SQL. A role with the documented partman_user privileges can store SQL rather than a decoder function name. When an affected operation later uses the poisoned value, including pg_partman_bgw maintenance for a text- or UUID-keyed set, the SQL executes with the operation's privileges, which can be the default PostgreSQL superuser background-worker role. The persistent row can restore elevated access on later ticks, and successful exploitation can permit database-wide compromise and operating-system command execution as the PostgreSQL service account. This issue is fixed in version 5.5.0.

MapServer

MapServer is a system for developing web-based GIS applications. Prior to 8.6.4, MapServer's PostGIS runtime filter translation in src/mappostgis.cpp and msPostGISLayerTranslateFilter() treats a filteritem as numeric when CONNECTIONTYPE POSTGIS and metadata such as gml_<item>_type=Integer are configured, but it does not verify that attacker-controlled CGI qstring or OGC API Features featureId input is a numeric literal. The unquoted input is concatenated into the generated PostgreSQL/PostGIS predicate, allowing an unauthenticated remote attacker with access to an affected query endpoint to bypass predicates, enumerate unintended records, perform boolean-based or time-based SQL injection, and increase database load. The issue does not by itself establish database modification capabilities. This issue is fixed in version 8.6.4.
