Уязвимость драйвера JDBC (PgJDBC) для подключения Java-программ к базе данных PostgreSQL, позволяющая нарушителю проводить XXE-атаки

A weakness was found in postgresql-jdbc before version 42.2.5. It was possible to provide an SSL Factory and not check the host name if a host name verifier was not provided to the driver. This could lead to a condition where a man-in-the-middle attacker could masquerade as a trusted server by providing a certificate for the wrong host, as long as it was signed by a trusted CA.

PostgreSQL JDBC Driver (aka PgJDBC) before 42.2.13 allows XXE.

pgjdbc is the offical PostgreSQL JDBC Driver. A security hole was found in the jdbc driver for postgresql database while doing security research. The system using the postgresql library will be attacked when attacker control the jdbc url or properties. pgjdbc instantiates plugin instances based on class names provided via `authenticationPluginClassName`, `sslhostnameverifier`, `socketFactory`, `sslfactory`, `sslpasswordcallback` connection properties. However, the driver did not verify if the class implements the expected interface before instantiating the class. This can lead to code execution loaded via arbitrary classes. Users using plugins are advised to upgrade. There are no known workarounds for this issue.
