Linux Kernel 2.6.16.9 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, which was classified as problematic, was found in Linux Kernel 2.6.16.9 (Operating System). Affected is some unknown processing. 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:

net/ipv4/netfilter/ip_tables.c in the IPv4 implementation in the Linux kernel before 2.6.39 does not place the expected \0 character at the end of string data in the values of certain structure members, which allows local users to obtain potentially sensitive information from kernel memory by leveraging the CAP_NET_ADMIN capability to issue a crafted request, and then reading the argument to the resulting modprobe process.

The issue has been introduced in 03/20/2006. The weakness was released 06/22/2011 as Bug 689327 as not defined bug report (Bugzilla). The advisory is shared for download at bugzilla.redhat.com. This vulnerability is traded as CVE-2011-1171 since 03/03/2011. The exploitability is told to be easy. The attack needs to be approached locally. The exploitation doesn't require any form of authentication. There are neither technical details nor an exploit publicly available. The MITRE ATT&CK project declares the attack technique as T1592.

The vulnerability was handled as a non-public zero-day exploit for at least 1920 days. During that time the estimated underground price was around $0-$5k. The vulnerability scanner Nessus provides a plugin with the ID 67081 (CentOS 5 : kernel (CESA-2011:0833)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family CentOS Local Security Checks. The commercial vulnerability scanner Qualys is able to test this issue with plugin 165567 (SUSE Enterprise Linux Security Update Linux Kernel (SUSE-SA:2011:031)).

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 X-Force (66183), Tenable (67081), SecurityFocus (BID 46919†) and Vulnerability Center (SBV-31990†). Entries connected to this vulnerability are available at VDB-57033, VDB-61066, VDB-61064 and VDB-57962. Once again VulDB remains the best source for vulnerability data.
