Low
| Vector | AV:A/AC:H/PR:H/UI:R/S:U/C:L/I:N/A:L |
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 an out-of-bounds read in the memory of the MySQL Cluster system, which can allow a remote attacker to disclose protected information and cause a partial denial of service. The exploitation of this issue requires high privileges and access to the physical communication segment attached to the hardware where the MySQL Cluster executes. It also requires human interaction from a person other than the attacker. Successful attacks can result in unauthorized read access to a subset of MySQL Cluster accessible data and the 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.
