Multi-Tenant LoadMaster MT_7.1.35.3 Release Notes

Refer to the sections below for details about firmware version MT_7.1.35.3. This was released on 6th December 2017.

Feature Enhancements

  • LoadMaster VNFs are now able to download GEO IP blacklist and Web Application Firewall (WAF) commercial rules.

Issues Resolved


Previously, deleting a VLAN and rebooting the Multi-Tenant host caused inaccessibility issues for VNFs on other VLANs. Now, VNF accessibility using VLAN is maintained after rebooting the Multi-Tenant host.


Fixed an issue that caused the Multi-Tenant LoadMaster to become unreachable when running a script to add a large number of VLANs.

Known Issues


A critical vulnerability (CVE-2018-9091) in the Multi-Tenant LoadMaster Operating System (MT-LMOS) related to Session Management could allow an unauthorized, remote attacker to bypass security protections, gain system privileges, and execute elevated commands such as ls, ps, cat, and so on, thereby compromising the system. Through this remote execution, in certain cases, exposure of sensitive system data such as certificates, private keys, and other information may be possible.

Further information can be found here: Mitigation For Remote Access Execution Vulnerability.


RADIUS-based users do not get the correct Web User Interface (WUI) administration permissions when WUI Session Management is enabled.


For newly-created VLANs, the selectable VLAN ID for the VNF does not match the VLAN ID on the Multi-Tenant interface list.


In certain scenarios, an incorrect link status displays.


The following error message appears if no local users are configured on the Multi-Tenant host WUI: '_RO_USERS: No such file or directory'. There is no functional impact relating to this error.


Users cannot apply a WUI certificate using the RESTful API or WUI.


VLAN IDs can be referenced using their HEX identifiers or the equivalent integer value. In cases where multiple VLANs are configured, this leads to difficulty identifying the appropriate VLAN ID.


The following error message displays on the WUI if a duplicate VLAN ID is used: 'Duplicate VLAN id <vlan ID> Cache-Control: nocache'.


High Availability (HA) does not work with LoadMaster firmware version LTS on the Multi-Tenant LoadMaster.
