CVE-2021-2011

CVSS v3.1

7.2

High

VectorAV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H
Name of the Vulnerable Software and Affected Versions MySQL Client versions 5.7.32 and prior MySQL Client versions 8.0.22 and prior
Description The issue is related to the C API component of the MySQL Client product, which allows an unauthenticated attacker with network access via multiple protocols to compromise the MySQL Client. Successful attacks can result in the unauthorized ability to cause a hang or frequently repeatable crash of the MySQL Client, leading to a denial of service. The vulnerability is difficult to exploit and can be triggered remotely.
Recommendations For MySQL Client versions 5.7.32 and prior, update to a version later than 5.7.32 to resolve the issue. For MySQL Client versions 8.0.22 and prior, update to a version later than 8.0.22 to resolve the issue. As a temporary workaround, consider restricting network access to the MySQL Client to minimize the risk of exploitation.
