AVM KEN! 1.3.10 Directory Traversal Vulnerability
A remote user on the local network is capable of retrieving any known file from a machine running AVM KEN!. This is accomplished by appending ../ to a URL utilizing port 3128 to escape the regular web file structure, and appending the remaining path onto the request.
A denial of service attack could also be launched against AVM KEN! by sending random characters to port 3128. A restart would be required in order to regain normal functionality.
