| Vector | AV:N/AC:L/Au:S/C:N/I:P/A:P |
Name of the Vulnerable Software and Affected Versions
MySQL Server versions 8.0.27 and prior
Description
The issue is related to insufficient input validation in the Server: Optimizer component of the MySQL Server system management database. This can be exploited by a remote attacker to cause a denial of service using the MySQL network protocol. Successful attacks can result in unauthorized access to update, insert, or delete some of the MySQL Server accessible data and can cause a partial denial of service of MySQL Server. The vulnerability can also lead to a hang or frequently repeatable crash of MySQL Server.
Recommendations
For versions 8.0.27 and prior, update to a version that includes the fix for this issue to prevent exploitation.
As a temporary workaround, consider restricting network access to the MySQL Server to minimize the risk of exploitation.
Restrict access to the Server: Optimizer component to prevent unauthorized actions until a patch is available.
