An unprivileged user of <filename>dblink</filename>
|
||||
or <filename>postgres_fdw</filename> could bypass the checks intended
|
||||
to prevent use of server-side credentials, such as
|
||||
a <filename>~/.pgpass</filename> file owned by the operating-system
|
||||
user running the server. Servers allowing peer authentication on
|
||||
local connections are particularly vulnerable. Other attacks such
|
||||
as SQL injection into a <filename>postgres_fdw</filename> session
|
||||
are also possible.
|
||||
Attacking <filename>postgres_fdw</filename> in this way requires the
|
||||
ability to create a foreign server object with selected connection
|
||||
parameters, but any user with access to <filename>dblink</filename>
|
||||
could exploit the problem.
|
||||
In general, an attacker with the ability to select the connection
|
||||
parameters for a <application>libpq</application>-using application
|
||||
could cause mischief, though other plausible attack scenarios are
|
||||
harder to think of.
|
