CVSS v2.0

7.5

High

VectorAV:N/AC:L/Au:S/C:N/I:P/A:C
Name of the Vulnerable Software and Affected Versions MySQL Server versions 8.0.40 and prior MySQL Server versions 8.4.3 and prior MySQL Server versions 9.1.0 and prior
Description The issue is related to the InnoDB component of MySQL Server, allowing an attacker with high privileges and network access via multiple protocols to compromise the server. Successful attacks can result in unauthorized ability to cause a hang or frequently repeatable crash of MySQL Server, as well as unauthorized update, insert, or delete access to some of MySQL Server's accessible data. The vulnerability can be easily exploited and may lead to a denial-of-service (DOS) condition.
Recommendations For MySQL Server versions 8.0.40 and prior, update to a version later than 8.0.40 to resolve the issue. For MySQL Server versions 8.4.3 and prior, update to a version later than 8.4.3 to resolve the issue. For MySQL Server versions 9.1.0 and prior, update to a version later than 9.1.0 to resolve the issue. As a temporary workaround, consider restricting network access to the MySQL Server to minimize the risk of exploitation.
