Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
1) Integer overflow
EUVDB-ID: #VU53231
Risk: Medium
CVSSv4.0: 7.2 [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/E:U/U:Green]
CVE-ID: CVE-2021-32027
CWE-ID:
CWE-190 - Integer overflow
Exploit availability: No
DescriptionThe 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.
Install updates from vendor's repository.
