Man-in-the-Middle (MitM)

postgresql is vulnerable to man-in-the-middle attacks. A man-in-the-middle attacker can inject arbitrary SQL queries when a connection is first created when the server is configured to use trust authentication with a 'clientcert' requirement or to utilize 'cert' authentication...

GaussDB Kernel: Checking All Local Entries Using Trust Authentication in the pg_hba.conf File

Trust authentication assumes that all users who can connect to the server can access the database. This method is convenient on single-user workstations but unsuitable for multi-user machines. As a result, you are advised to check all local entries that use trust authentication. Copyright C 2020...

Privilege Escalation

postgresql is vulnerable to privilege escalation. The vulnerability exists as an authenticated attacker could use dblink to possibly escalate privileges on systems with "trust" or "ident" authentication configured. Please note that dblink functionality is not enabled by default, and can only by...

ZSQL: Local Trust Authentication

In local trust authentication mode, a database user can connect to the local database in password-free mode using zsql after the local connection is authenticated. Then, this user can maintain database accounts. You are advised to disable the local trust authentication during service running...

Updated postgresql packages fix multiple security vulnerabilities

Updated postgresql packages fix security vulnerabilities: Granting a role without ADMIN OPTION is supposed to prevent the grantee from adding or removing members from the granted role, but this restriction was easily bypassed by doing SET ROLE first. The security impact is mostly that a role memb...

dblink allows proxying of database connections via 127.0.0.1

PostgreSQL 8.1 and probably later versions, when local trust authentication is enabled and the Database Link library dblink is installed, allows remote attackers to access arbitrary accounts and execute arbitrary SQL queries via a dblink host parameter that proxies the connection from 127.0.0.1...

PostgreSQL privilege escalation via dblink

The DBLink module in PostgreSQL 8.2 before 8.2.6, 8.1 before 8.1.11, 8.0 before 8.0.15, 7.4 before 7.4.19, and 7.3 before 7.3.21, when local trust or ident authentication is used, allows remote attackers to gain privileges via unspecified vectors. NOTE: this issue exists because of an incomplete...
