-------------------------------------------------------------------------------- Fedora Update Notification FEDORA-2018-92f04c6b61 2018-05-15 19:59:59.036932 -------------------------------------------------------------------------------- Name : mysql-mmm Product : Fedora 26 Version : 2.2.1 Release : 20.fc26 URL : http://mysql-mmm.org Summary : Multi-Master Replication Manager for MySQL Description : MMM (MySQL Master-Master Replication Manager) is a set of flexible scripts to perform monitoring/failover and management of MySQL Master-Master replication configurations (with only one node writable at any time). The toolset also has the ability to read balance standard master/slave configurations with any number of slaves, so you can use it to move virtual IP addresses around a group of servers depending on whether they are behind in replication. In addition to that, it also has scripts for data backups, resynchronization between nodes etc. -------------------------------------------------------------------------------- Update Information: # Multi-Master Replication Manager for MySQL mmm_agentd Remote Command Injection Vulnerabilities This update adds data sanitization to inputs for the mmm agent. Multiple exploitable remote command injection vulnerabilities exist in the MySQL Master-Master Replication Manager (MMM) mmm_agentd daemon 2.2.1. mmm_agentd commonly runs with root privileges and does not require authentication by default. A specially crafted MMM protocol message can cause a shell command injection resulting in arbitrary command execution with the privileges of the mmm_agentd process. An attacker that can initiate a TCP session with mmm_agentd can trigger these vulnerabilities. The impact of these vulnerabilities can be lessened by configuring mmm_agentd to require TLS mutual authentication and by using network ACLs to prevent hosts other than legitimate mmm_mond hosts from accessing mmm_agentd. For example on Linux iptables rules can be used to block access to the port mmm_agent is listening on from all hosts except the mmm_monitor. The configuration of ssl can be used where firewall rules are not practical. See Socket Documentation http://mysql-mmm.org/mysql-mmm.html#SEC58 Add to mmm_common.conf <socket> type ssl cert_file /etc/ssl/certs/www.example.com.bundle.crt key_file /etc/ssl/certs/www.example.com.key ca_file /etc/ssl/certs/ca-bundle.crt # or ca-certificates.crt </socket> Now only those with access to the private key can send commands. Whilst your web server certificate will do the job, you may consider registering a dedicated certificate just for this task. NOTE: By now there are a some good alternatives to MySQL-MMM.
