NetBSD up to 3.0 Intel Random Number Generator security check

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.

Summaryinfo

A vulnerability identified as problematic has been detected in NetBSD up to 3.0. The affected element is an unknown function of the component Intel Random Number Generator. Performing a manipulation results in security check. This vulnerability is identified as CVE-2006-1833. There is not any exploit available. It is recommended to apply a patch to fix this issue.

Detailsinfo

A vulnerability classified as critical has been found in NetBSD up to 3.0 (Operating System). This affects some unknown functionality of the component Intel Random Number Generator. The manipulation with an unknown input leads to a security check vulnerability. CWE is classifying the issue as CWE-358. The product does not implement or incorrectly implements one or more security-relevant checks as specified by the design of a standardized algorithm, protocol, or technique. This is going to have an impact on confidentiality, and integrity. The summary by CVE is:

Intel RNG Driver in NetBSD 1.6 through 3.0 may incorrectly detect the presence of the pchb interface, which will cause it to always generate the same random number, which allows remote attackers to more easily crack encryption keys generated from the interface.

The weakness was released 04/13/2006 by Matthias Scheler with Debian (Website). It is possible to read the advisory at ftp.netbsd.org. This vulnerability is uniquely identified as CVE-2006-1833 since 04/19/2006. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. The technical details are unknown and an exploit is not publicly available. The attack technique deployed by this issue is T1211 according to MITRE ATT&CK.

Upgrading to version 2.0.4 eliminates this vulnerability. Applying a patch is able to eliminate this problem. The bugfix is ready for download at netbsd.org. The best possible mitigation is suggested to be patching the affected component.

The vulnerability is also documented in the databases at X-Force (25786), SecurityFocus (BID 17496†), OSVDB (24577†), Secunia (SA19585†) and SecurityTracker (ID 1015907†). Entries connected to this vulnerability are available at VDB-2150 and VDB-2149. Be aware that VulDB is the high quality source for vulnerability data.
