Vulnerability Published: 2021-03-19
Patch Published: 2021-02-22
CVE [?]: CVE-2021-27928
CPE [?]: cpe:/a:mariadb:mariadb
Synopsis
The remote database server is affected by a vulnerability
Description
The version of MariaDB installed on the remote host is prior to 10.4.18. It is, therefore, affected by a vulnerability as referenced in the mdb-10418-rn advisory.
- A remote code execution issue was discovered in MariaDB 10.2 before 10.2.37, 10.3 before 10.3.28, 10.4 before 10.4.18, and 10.5 before 10.5.9; Percona Server through 2021-03-03; and the wsrep patch through 2021-03-03 for MySQL. An untrusted search path leads to eval injection, in which a database SUPER user can execute OS commands after modifying wsrep_provider and wsrep_notify_cmd. NOTE: this does not affect an Oracle product. (CVE-2021-27928)
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
Solution
Upgrade to MariaDB version 10.4.18 or later.
