Raspberry Pi 2 NCP6343 Camera Flash denial of service
|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.
A vulnerability, which was classified as problematic, has been found in Raspberry Pi 2. This issue affects an unknown code block of the component NCP6343. The manipulation as part of a Camera Flash leads to a denial of service vulnerability. Using CWE to declare the problem leads to CWE-404. Impacted is availability.
The weakness was published 02/07/2015 by PeterO as Why is the PI2 camera-shy ? as not defined posting (Forum). It is possible to read the advisory at raspberrypi.org. The vendor was not involved in the public release. The exploitation is known to be difficult. Attacking locally is a requirement. No form of authentication is needed for a successful exploitation. Technical details are unknown but a public exploit is available. The pricing for an exploit might be around USD $0-$5k at the moment (estimation calculated on 07/10/2017). The attack technique deployed by this issue is T1499 according to MITRE ATT&CK. Due to its background and reception, this vulnerability has a historic impact. The advisory points out:
I have discovered that my PI2 is camera-shy ! Taking it's picture with a flash causes an instant power off !
A public exploit has been developed by PeterO and been published immediately after the advisory. It is declared as proof-of-concept. The exploit is available at raspberrypi.org.
The posting contains the following remark:
If you need to use your Pi 2 in a situation where it might be flashed at, our advice is to cover U16 (make sure you get the sides too) – the current easy fix is to use a small blob of Sugru or Blu-Tak covering the whole component (someone in the forums used a pellet of bread: the first yeasted bug fix we have encountered), or simply put the Pi in an opaque case.
