EUVDB-ID: #VU50656
Risk: Low
CVSSv3.1: 3.8 [CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2021-20229
CWE-ID:
CWE-264 - Permissions, Privileges, and Access Controls
Exploit availability: No
DescriptionThe vulnerability allows a remote user to gain access to sensitive information.
The vulnerability exists due to application does not properly impose security restrictions. A user having a SELECT
privilege on an individual column can craft a special
query that returns all columns of the table. Additionally, a stored view that uses column-level privileges will have
incomplete column-usage bitmaps. In installations that depend on column-level
permissions for security, it is recommended to execute CREATE OR REPLACE
on
all user-defined views to force them to be re-parsed.
Update the affected packages.
