EUVDB-ID: #VU50656
Risk: Low
CVSSv3.1:
CVE-ID: CVE-2021-20229
CWE-ID:
Exploit availability:
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.
