Security Bulletin

This security bulletin contains information about 4 vulnerabilities.

1) Missing Encryption of Sensitive Data

EUVDB-ID: #VU58113

Risk: Medium

CVSSv3.1: 5.9 [CVSS:3.1/AV:A/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2021-23214

CWE-ID: CWE-311 - Missing Encryption of Sensitive Data

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform MitM attack.

The vulnerability exists due to the way PostgreSQL handles encrypted connections. When the server is configured to use trust authentication with a clientcert requirement or to use cert authentication, a man-in-the-middle attacker can inject arbitrary SQL queries when a connection is first established, despite the use of SSL certificate verification and encryption.

Mitigation

Update the affected package postgresql10 to the latest version.

2) Missing Encryption of Sensitive Data

EUVDB-ID: #VU58114

Risk: Medium

CVSSv3.1: 5.9 [CVSS:3.1/AV:A/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2021-23222

CWE-ID: CWE-311 - Missing Encryption of Sensitive Data

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform MitM attack.

The vulnerability exists due to the way the libpq process in PostgreSQL handles encrypted connections. A man-in-the-middle attacker can inject false responses to the client's first few queries, despite the use of SSL certificate verification and encryption. The attacker can exfiltrate the client's password or other confidential data that might be transmitted early in a session.

Mitigation

Update the affected package postgresql10 to the latest version.

3) Permissions, Privileges, and Access Controls

EUVDB-ID: #VU63126

Risk: Medium

CVSSv3.1: 4.7 [CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-1552

CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls

Exploit availability: No

Description

The vulnerability allows a remote user to bypass implemented security restrictions.

The vulnerability exists due to incorrectly imposed security restrictions in Autovacuum, REINDEX, CREATE INDEX, REFRESH MATERIALIZED VIEW, CLUSTER, and pg_amcheck. A remote authenticated user with permission to create non-temp objects can execute arbitrary SQL functions under a superuser identity and escalate privileges within the application.

4) Permissions, Privileges, and Access Controls

EUVDB-ID: #VU66429

Risk: Low

CVSSv3.1: 3.7 [CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:L/I:L/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-2625

CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls

Exploit availability: No

Description

The vulnerability allows a remote user to escalate privileges within the database.

The vulnerability exists due to extension scripts can replace objects that do not belong to the extension when using the CREATE OR REPLACE or CREATE IF NOT EXISTS commands. A remote user with (1) permissions to create non-temporary objects in at least one schema, (2) ability to lure or wait for an administrator to create or update an affected extension in that schema, and (3) ability to lure or wait for a victim to use the object targeted in CREATE OR REPLACE or CREATE IF NOT EXISTS can run arbitrary code as the victim role.

Mitigation

Update the affected package postgresql10 to the latest version.
