(Belkin) Cisco Linksys E4200 Router Multiple Vulnerabilities

Date Disclosed:

Date Patched:
No patch available, product is at end-of-life. Customers may be entitled to a free upgrade to the EA4500 if security issues persist or become a problem.


Affected Software:
Cisco Linksys E4200 running firmware 1.0.05 Build 7

There are multiple vulnerabilities in the 1.0.05 Build 7 firmware on Cisco Linsys E4200 routers, including the following: a local file include vulnerability, a password disclosure vulnerability, a security bypass vulnerability, a clickjacking vulnerability, and multiple cross site scripting vulnerabilities.


Code Execution:


Elevation of Privilege via Information Disclosure (CVE-2013-2680 & CVE-2013-2678)
Exploitation of this vulnerability will grant an attacker access to sensitive information, such as passwords, or the ability to execute local scripts. These can be used by the remote attacker to elevate their privileges on the device.
Security Bypass (CVE-2013-2681)
This vulnerability allows an attacker to bypass certain security restrictions on the device, allowing the attacker to gain unauthorized access to the device.
Clickjacking (CVE-2013-2682)
This vulnerability can be used to disguise page elements, such as buttons or links, as elements the user would consider legitimate. However, the transparent underlying page has different functionality than is visually displayed to the user, so the attacker is able to display a page in a way such that the user unknowingly performs actions on the translucent page. This can be used by attackers to trick users into performing actions on the web page that they would have otherwise not performed.
Cross-site Scripting (CVE-2013-2679 & CVE-2013-2684)
Exploitation of these vulnerabilities is possible via maliciously crafted URLs that contain malicious scripts. This may allow an attacker to siphon sensitive information or execute arbitrary web scripts within the context of the browser.

No mitigation currently exists.

BeyondTrust's Retina® Network Security Scanner scans devices to detect for this vulnerability.
