Security Bulletin

This security bulletin contains information about 5 vulnerabilities.

1) Untrusted search path

EUVDB-ID: #VU45748

Risk: Medium

CVSSv4.0: 1.3 [CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Green]

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 repository.

Q & A

Can this vulnerability be exploited remotely?

Yes. This vulnerability can be exploited by a remote authenticated user 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: #VU45749

Risk: Medium

CVSSv4.0: 1.2 [CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2020-14350

CWE-ID: CWE-426 - Untrusted Search Path
