|

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 might be vulnerable including E4200, E3200, E3000,
|
||||
E2500, E2100L, E2000, E1550, E1500, E1200, E1000, E900. This module was tested
|
||||
successfully against an E1500 v1.0.5.
