CVE-2020-14771

CVSS v2.0

3.5

Low

VectorAV:N/AC:M/Au:S/C:N/I:N/A:P
Name of the Vulnerable Software and Affected Versions: MySQL Server versions 5.7.31 and prior MySQL Server versions 8.0.21 and prior
Description: The issue is related to insufficient input validation in the Server: Security: LDAP Auth component of MySQL Server. It allows a high-privileged attacker with network access via multiple protocols to compromise MySQL Server. Successful attacks can result in unauthorized ability to cause a partial denial of service (partial DOS) of MySQL Server.
Recommendations: For MySQL Server versions 5.7.31 and prior, update to a version later than 5.7.31 to resolve the issue. For MySQL Server 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 Server: Security: LDAP Auth component to minimize the risk of exploitation.
