(confirmed by vendor)
Design flaws:
* Telnet is available and cannot be disabled (confirmed by vendor)
* SSHv1 enabled by default if SSH is enabled (confirmed by vendor)
Vendor response:
TP-Link are not convinced that these flaws should be repaired.
TP-Link's Internet presence -- or at least DNS -- is available only
intermittently. Most emails bounced. Lost contact with vendor, but
did confirm that development lead is now on holiday and will not
return for at least a week.
Initial vendor reaction was to recommend purchase of "3-series"
switches. Vendor did not offer reasons why "3-series" switches would
be more secure, apart from lack of telnet service. Vendor confirmed
that no development time can be allocated to securing "2-series"
product and all focus has shifted to newer products.
(TL-SG2008 first product availability July 2014...)
Vendor deeply confused about security of DES/3DES, MD5, claimed that
all security is relative. ("...[E]ven SHA-1 can be cracked, they just
have different security level.")
Fix availability:
None.
Work-arounds advised:
None possible. Remove products from network.
