|
'Description' => %q{
|
|
Some Linksys E-Series Routers are vulnerable to an unauthenticated OS command
|
|
injection. This vulnerability was used from the so-called "TheMoon" worm. There
|
|
are many Linksys systems that are potentially vulnerable, including E4200, E3200, E3000,
|
|
E2500, E2100L, E2000, E1550, E1500, E1200, E1000, and E900. This module was tested
|
|
successfully against an E1500 v1.0.5.
