A flaw was found in the mysql-wsrep component of mariadb. Lack of input sanitization in wsrepsstmethod allows for command injection that can be exploited by a remote attacker to execute arbitrary commands on galera cluster nodes. This threatens the system's confidentiality, integrity, and availability. This flaw affects mariadb versions before 10.1.47, before 10.2.34, before 10.3.25, before 10.4.15 and before 10.5.6.

An issue was discovered in Percona XtraDB Cluster before 5.7.28-31.41.2. A bundled script inadvertently sets a static transitionkey for SST processes in place of the random key expected.

MariaDB have noted in their release notes that reserved CVE-2017-15365 has been fixed in version 10.2.10[1], however they have not described how or what the vulnerability was. This CVE is also mentioned to affect Percona[2] with the fix is described as:

"Added access checks for DDL commands to make sure they do not get replicated if they failed without proper permissions"

A comparison with the MariaDB 10.2.10 changelog[3] and Percona description finds this commit[4], which seems a likely candidate for both describing and fixing the vulnerability. The vulnerable code block in sql/eventdataobjects.cc is also present in version 10.1, suggesting that it is also affected.
