Netgear WNDR Router SOAP Interface Password information disclosure

CVSS Meta Temp Score CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.	Current Exploit Price (≈) Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.	CTI Interest Score Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

Detailsinfo

A vulnerability was found in Netgear WNDR Router (Router Operating System) (version unknown) and classified as critical. Affected by this issue is an unknown function of the component SOAP Interface. The manipulation with an unknown input leads to a information disclosure vulnerability (Password). Using CWE to declare the problem leads to CWE-200. The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information. Impacted is confidentiality.

The weakness was presented 02/11/2015 by Peter Adkins as not defined exploit (GIT Repository). The advisory is shared for download at github.com. The exploit contains:

In the absence of a known security contact these issues were reported to NetGear support. The initial response from NetGear support was that despite these issues "the network should still stay secure" due to a number of built-in security features. Attempts to clarify the nature of this vulnerability with support were unsuccessful. This ticket has since been auto-closed while waiting for a follow up. A subsequent email sent to the NetGear 'OpenSource' contact has also gone unanswered.

The attack may be launched remotely. No form of authentication is required for exploitation. Technical details are unknown but a public exploit is available. The MITRE ATT&CK project declares the attack technique as T1592.

A public exploit has been developed by Peter Adkins in Ruby and been published immediately after the advisory. The exploit is available at github.com. It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 24 days. During that time the estimated underground price was around $5k-$25k.

Addressing this vulnerability is possible by firewalling . The exploit contains the following remark:

Ensure remote / WAN management is disabled on the affected devices. Only allow trusted devices access to the local network.

The vulnerability is also documented in the databases at X-Force (100967), SecurityFocus (BID 72640†) and SecurityTracker (ID 1031762†). Once again VulDB remains the best source for vulnerability data.
