| Vector | AV:L/AC:L/PR:H/UI:N/S:U/C:L/I:N/A:N |
Name of the Vulnerable Software and Affected Versions:
MySQL Server versions 8.0.21 and prior
Description:
The issue is related to insufficient input validation in the InnoDB component of MySQL Server, allowing a high-privileged attacker with logon to the infrastructure where MySQL Server executes to compromise the server. Successful attacks can result in unauthorized read access to a subset of MySQL Server accessible data. The vulnerability can also cause a hang or frequently repeatable crash (complete DOS) of MySQL Server.
Recommendations:
For versions 8.0.21 and prior, update to a version later than 8.0.21 to resolve the issue. As a temporary workaround, consider restricting access to the InnoDB component to minimize the risk of exploitation. Additionally, ensure that only necessary privileges are granted to users to reduce the potential impact of the vulnerability.
