CVE-2020-14550

CVSS v3.1

5.3

Medium

VectorAV:N/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:H
Name of the Vulnerable Software and Affected Versions: MySQL Client versions 5.6.48 and prior MySQL Client versions 5.7.30 and prior MySQL Client versions 8.0.20 and prior
Description: The issue is related to insufficient input validation in the C API component of the MySQL Client product. It allows a low-privileged 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.
Recommendations: For versions 5.6.48 and prior, update to a version later than 5.6.48 to resolve the issue. For versions 5.7.30 and prior, update to a version later than 5.7.30 to resolve the issue. For versions 8.0.20 and prior, update to a version later than 8.0.20 to resolve the issue. As a temporary workaround, consider restricting network access to the MySQL Client to minimize the risk of exploitation.
