CVE-ID: CVE-2015-8011

CWE-ID: CWE-119 - Memory corruption

Exploit availability: No

Can this vulnerability be exploited remotely?

Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the Internet.

Is there known malware, which exploits this vulnerability?

No. We are not aware of malware exploiting this vulnerability.

2) Untrusted search path

EUVDB-ID: #VU45748

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-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.

The vulnerability exists due to the way PostgreSQL handles search_path during replications. Users of a replication publisher or subscriber database can create objects in the public schema and harness them to execute arbitrary SQL functions under the identity running replication, often a superuser.

Mitigation

Install updates from vendor's website.
