Security Bulletin

This security bulletin contains information about 3 vulnerabilities.

1) Improper Authorization

EUVDB-ID: #VU25333

Risk: Low

CVSSv3.1:

CVE-ID: CVE-2020-1720

CWE-ID: CWE-285 - Improper Authorization

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform unauthorized modification of data in database.

The vulnerability exists due to the ALTER ... DEPENDS ON EXTENSION sub-commands do not perform authorization checks, which can allow an unprivileged user to drop any function, procedure, materialized view, index, or trigger under certain conditions. This attack is possible if an administrator has installed an extension and an unprivileged user can CREATE, or an extension owner either executes DROP EXTENSION predictably or can be convinced to execute DROP EXTENSION.

Mitigation

Install updates from vendor's website.

2) Untrusted search path

EUVDB-ID: #VU45748

Risk: Medium

CVSSv3.1:

CVE-ID: CVE-2020-14349

CWE-ID: CWE-426 - Untrusted Search Path

Exploit availability: No

Description

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

Mitigation

Install updates from vendor's website.
