Integer overflow in PostgreSQL - CVE-2021-32027

Vulnerability identifier: #VU53231

CSH Severity: Medium

CVSS v4: 9.2 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]

CVE-ID: CVE-2021-32027

CWE-ID: CWE-190

Exploitation vector: Remote access

Exploit availability: No public exploit available

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.
