CVE-2020-15180 – Affects Percona XtraDB Cluster
Galera replication technology, a key component of Percona XtraDB Cluster, suffered from a remote code execution vulnerability. Percona has been working with the vendor since early September on this issue and has made releases available to address the problem.
A malicious party with access to the WSREP service port (4567/TCP) as well as prerequisite knowledge of the configuration of the Galera cluster name is required in order to exploit this vulnerability, which leads to remote code execution via the WSREP protocol.
Fixes are available in Percona XtraDB Cluster versions:
Percona would like to thank all the Percona staff involved in the resolution of this issue.
