Linux Kernel 2.6.16.9 bcm_connect 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.

A vulnerability was found in Linux Kernel 2.6.16.9 (Operating System). It has been classified as problematic. Affected is the function bcm_connect. The manipulation with an unknown input leads to a information disclosure vulnerability. CWE is classifying the issue as CWE-200. The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information. This is going to have an impact on confidentiality. CVE summarizes:

The bcm_connect function in net/can/bcm.c (aka the Broadcast Manager) in the Controller Area Network (CAN) implementation in the Linux kernel 2.6.36 and earlier creates a publicly accessible file with a filename containing a kernel memory address, which allows local users to obtain potentially sensitive information about kernel memory use by listing this filename.

The issue has been introduced in 03/20/2006. The weakness was published 12/29/2010 by Dan Rosenberg as Bug 664544 as not defined bug report (Bugzilla). The advisory is shared for download at bugzilla.redhat.com. This vulnerability is traded as CVE-2010-4565. The exploitability is told to be easy. The attack needs to be approached locally. The exploitation doesn't require any form of authentication. Technical details and a public exploit are known. The MITRE ATT&CK project declares the attack technique as T1592.

The exploit is shared for download at packetstormsecurity.com. It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 1745 days. During that time the estimated underground price was around $0-$5k. The vulnerability scanner Nessus provides a plugin with the ID 68416 (Oracle Linux 5 / 6 : Unbreakable Enterprise kernel (ELSA-2011-2015)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Oracle Linux Local Security Checks. The commercial vulnerability scanner Qualys is able to test this issue with plugin 155444 (Oracle Enterprise Linux Update for Unbreakable Enterprise Kernel (ELSA-2011-2015)).

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.

The vulnerability is also documented in the databases at Tenable (68416), SecurityFocus (BID 44661†) and Vulnerability Center (SBV-29570†). Similar entries are available at VDB-55858, VDB-61060 and VDB-63670.
