Overview

 

Linksys EA series routers running the Linksys SMART WiFi firmware contain multiple vulnerabilities.

Description

 

 

 

 

 

 

 

CWE-320: Key Management Errors - CVE-2014-8243   An unauthenticated attacker on the local area network (LAN) can read the router's .htpassword file by requestinghttp(s)://<router_ip>/.htpasswd. The .htpasswd file contains the MD5 hash of the administrator password. CWE-200: Information Exposure - CVE-2014-8244 A remote, unauthenticated user can issue various JNAP calls by sending specially-crafted HTTP POST requests tohttp(s)://<router_ip>/JNAP/. Depending on the JNAP action that is called, the attacker may be able to read or modify sensitive information on the router. It should also be noted that the router exposes multiple ports to the WAN by default. Port 100080 and 52000 both expose the administrative web interface to WAN users. Depending on the model, additional ports may be exposed by default as well.
