| Vector | AV:N/AC:L/Au:S/C:N/I:N/A:C |
Name of the Vulnerable Software and Affected Versions
MySQL Server versions 8.0.20 and prior
Description
The issue is related to insufficient input validation in the MySQL Server component, specifically in the Security: Privileges subsystem. This can be exploited by a remote attacker with high privileges and network access via multiple protocols, potentially leading to a denial of service (DOS) condition where the MySQL Server hangs or crashes repeatedly.
Recommendations
For versions 8.0.20 and prior, update to a version that includes the fix for this issue.
As a temporary workaround, consider restricting network access to the MySQL Server to minimize the risk of exploitation.
Restrict access to the
Server: Security: Privileges component to minimize the risk of exploitation until a patch is available.Exploit
