9) Security features bypass

EUVDB-ID: #VU76042

Risk: Low

CVSSv3.1: 2 [CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:U/C:N/I:L/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2023-2455

CWE-ID: CWE-254 - Security Features

Exploit availability: No

Description

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

The vulnerability exists due to incomplete fix for #VU40402 (CVE-2016-2193) that did not anticipate a scenario involving function inlining. This scenario can happen under security definer functions or when a common user and query is planned initially and then re-used across multiple SET ROLEs. Applying an incorrect policy may permit a user to complete otherwise-forbidden reads and modifications.

This affects only databases that have used CREATE POLICY to define a row security policy.

Mitigation

Install updates from vendor's repository.

10) Security Features

EUVDB-ID: #VU40402

Risk: Medium

CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2016-2193

CWE-ID: CWE-254 - Security Features

Exploit availability: No

Description

The vulnerability allows a remote non-authenticated attacker to manipulate data.

PostgreSQL before 9.5.x before 9.5.2 does not properly maintain row-security status in cached plans, which might allow attackers to bypass intended access restrictions by leveraging a session that performs queries as more than one role.

Mitigation

Install updates from vendor's repository.
