pgpoolAdmin 4.0.1 officially released (2018/12/20)

PgPool Global Development Group has released a Security Update of pgpoolAdmin.

The purpose of this release is to address CVE-2018-16203, which allow an attacker to login without properly checking the authorization. Once getting into gpoolAdmin, the attacker can control Pgpool-II. Also it may be possible to obtain the superuser role of a PostgreSQL database.

This vulnability affects all versions of pgpoolAdmin. We recommend upgrade pgpoolAdmin to 4.0.1 immediately (remember that PgpoolAdmin 4.0.1 is compatible with Pgpool-II 3.4 or later).

PgPool Global Development Group would like to thank Fotios Rogkotis of DarkMatter for finding the security issue and giving us the detailed studies on it.
