CVSS v2.0
2.9
Low
| Vector | AV:A/AC:H/Au:S/C:P/I:N/A:P |
Name of the Vulnerable Software and Affected Versions
MySQL Cluster versions 7.4.34 and prior
MySQL Cluster versions 7.5.24 and prior
MySQL Cluster versions 7.6.20 and prior
MySQL Cluster versions 8.0.27 and prior
Description
The issue is related to a buffer read overflow in the memory when handling data nodes, which can allow an attacker to gain unauthorized access to protected information or cause a denial of service using multiple protocols. The vulnerability can be exploited by a high-privileged attacker with access to the physical communication segment attached to the hardware where the MySQL Cluster executes, compromising the MySQL Cluster. Successful attacks require human interaction from a person other than the attacker and can result in unauthorized read access to a subset of MySQL Cluster accessible data and unauthorized ability to cause a partial denial of service of MySQL Cluster.
Recommendations
For MySQL Cluster versions 7.4.34 and prior, update to a version later than 7.4.34 to resolve the issue.
For MySQL Cluster versions 7.5.24 and prior, update to a version later than 7.5.24 to resolve the issue.
For MySQL Cluster versions 7.6.20 and prior, update to a version later than 7.6.20 to resolve the issue.
For MySQL Cluster versions 8.0.27 and prior, update to a version later than 8.0.27 to resolve the issue.
As a temporary workaround, consider restricting access to the physical communication segment attached to the hardware where the MySQL Cluster executes to minimize the risk of exploitation.
