Security Advisory: TR-064 Vulnerability


In December 2016, a vulnerability was reported in some implementations of the TR-064 and TR-069 management protocol. These protocols are used by many ISPs to monitor CPE to maintain network quality/performance.  it is claimed that an attack has affected nearly a million routers in Germany (link).  An updated version of the Mirai bot (worm) is being used to exploit these routers.   Currently, there does not appear to be any CVE reference for this attack/vulnerability. It is also referred to as a Port 7547 SOAP Remote Execution Attack.


Note that this vulnerability/exploit is not Mirai itself - the Mirai bot is merely the framework/agent which conducts the attacks. Its previous version concentrated on IP cameras/IoT devices.  Note, at this stage, it is unclear why many sources refer to TR-069 as the vulnerability seems to only be in some implementations of TR-064 which is an earlier/different protocol but it may be that some vendors' implementations of TR-069 are affected.


DrayTek Products

No DrayTek products are affected by this vulnerability.  We do not use the TR-064 protocol and our TR-069 implementation is not vulnerable to this attack.  Regardless of this, it is always recommended that you keep your DrayTek router and other hardware up to date with the latest hardware and read vendor mailing lists (UK users can join here) as security improvements are regularly added and new exploits/vulnerabilities may surface.
