EUVDB-ID: #VU53232

Risk: Medium

CVSSv3.1: 6.7 [CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2021-32028

CWE-ID: CWE-401 - Improper Release of Memory Before Removing Last Reference ('Memory Leak')

Exploit availability: No

Description

The vulnerability allows a remote user to gain access to sensitive information.

The vulnerability exists due memory leak within the INSERT ... ON CONFLICT ... DO UPDATE command implementation. A remote authenticated database user can execute the affected command to read arbitrary bytes of server memory. In the default configuration, any authenticated database user can create prerequisite objects and complete this attack at will.

2) Integer overflow

EUVDB-ID: #VU53231

Risk: Medium

CVSSv3.1: 7.1 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2021-32027

CWE-ID: CWE-190 - Integer Overflow or Wraparound

Exploit availability: No

Description

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to integer overflow when processing certain SQL array values during array subscribing calculation. An authenticated database user can pass specially crafted data to the application, trigger integer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system and can be exploited by a remote unauthenticated attacker via SQL injection vulnerability in the frontend application.

Mitigation

Install update from vendor's website.
