| Vector | AV:L/AC:H/PR:H/UI:N/S:U/C:N/I:N/A:H |
Name of the Vulnerable Software and Affected Versions
MySQL Server versions 8.0.39 and prior
MySQL Server versions 8.4.2 and prior
MySQL Server versions 9.0.1 and prior
Description
The issue is related to the MySQL Server product, specifically the Server: Security: Privileges component. It is associated with unlimited resource allocation. An attacker with high privileges who logs in to the infrastructure where MySQL Server is executed can exploit this issue to compromise MySQL Server. Successful attacks can result in the unauthorized ability to cause a hang or frequently repeatable crash of MySQL Server, leading to a denial of service.
Recommendations
For MySQL Server versions 8.0.39 and prior, update to a version later than 8.0.39 to resolve the issue.
For MySQL Server versions 8.4.2 and prior, update to a version later than 8.4.2 to resolve the issue.
For MySQL Server versions 9.0.1 and prior, update to a version later than 9.0.1 to resolve the issue.
As a temporary workaround, consider restricting access to the MySQL Server infrastructure to minimize the risk of exploitation.
