Test ID:1.3.6.1.4.1.25623.1.0.812040
Category:Web application abuses
Title:Linksys Devices Multiple Vulnerabilities
Summary:Multiple Linksys devices are prone to multiple vulnerabilities.
Description:Summary:
Multiple Linksys devices are prone to multiple vulnerabilities.

Vulnerability Insight:
Multiple flaws exist due to:

- A crafted GET request can reboot the whole device or freeze the web interface
and the DHCP service. This action does not require authentication.

- An error in the web service, so a header injection can be triggered without
authentication.

- The session ID for administrative users can be fetched from the device from
LAN without credentials because of insecure session handling.

- An attacker can change any configuration of the device by luring a user to
click on a malicious link or surf to a malicious web-site.

- Insufficient validation of user input in Admin Interface.

Vulnerability Impact:
Successful exploitation will allow remote
attackers to conduct a denial-of-service, HTTP header injection, open redirect,
information disclosure, CSRF and XSS attacks on the affected device.

Linksys E2500 firmware version 3.0.02 (build 2)
