| Vector | AV:A/AC:H/PR:H/UI:R/S:U/C:H/I:H/A:H |
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 overflow in memory, allowing a remote attacker to execute arbitrary code. It is a difficult to exploit vulnerability that requires a high privileged attacker with access to the physical communication segment attached to the hardware where the MySQL Cluster executes. Successful attacks also require human interaction from a person other than the attacker, and can result in the takeover of MySQL Cluster.
Recommendations
For versions 7.4.34 and prior, update to a version later than 7.4.34.
For versions 7.5.24 and prior, update to a version later than 7.5.24.
For versions 7.6.20 and prior, update to a version later than 7.6.20.
For versions 8.0.27 and prior, update to a version later than 8.0.27.
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.
Fix
RCE
