Linux Kernel 2.6.16.9 ec_dev_ioctl access control

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 Linux Kernel 2.6.16.9. This vulnerability affects the function ec_dev_ioctl. The manipulation leads to access control. This vulnerability is listed as CVE-2010-3850. In addition, an exploit is available.

Detailsinfo

A vulnerability, which was classified as problematic, has been found in Linux Kernel 2.6.16.9 (Operating System). This issue affects the function ec_dev_ioctl. The manipulation with an unknown input leads to a access control vulnerability. Using CWE to declare the problem leads to CWE-264. Impacted is integrity. The summary by CVE is:

The ec_dev_ioctl function in net/econet/af_econet.c in the Linux kernel before 2.6.36.2 does not require the CAP_NET_ADMIN capability, which allows local users to bypass intended access restrictions and configure econet addresses via an SIOCSIFADDR ioctl call.

The issue has been introduced in 03/20/2006. The weakness was presented 12/30/2010 by Dan Rosenberg as Bug 644156 as confirmed bug report (Bugzilla). It is possible to read the advisory at bugzilla.redhat.com. The identification of this vulnerability is CVE-2010-3850. The exploitation is known to be easy. Attacking locally is a requirement. No form of authentication is needed for a successful exploitation. Technical details as well as a public exploit are known. The attack technique deployed by this issue is T1068 according to MITRE ATT&CK.

A public exploit has been developed by Dan Rosenberg in ANSI C and been published before and not just after the advisory. The exploit is available at securityfocus.com. It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 1746 days. During that time the estimated underground price was around $5k-$25k. The vulnerability scanner Nessus provides a plugin with the ID 50825 (Debian DSA-2126-1 : linux-2.6 - privilege escalation/denial of service/information leak), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Debian Local Security Checks. The commercial vulnerability scanner Qualys is able to test this issue with plugin 119077 (Linux Kernel Multiple Vulnerabilities).

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 Exploit-DB (15704), Tenable (50825), SecurityFocus (BID 45072†) and Vulnerability Center (SBV-29745†). See VDB-55569, VDB-55564, VDB-55563 and VDB-55559 for similar entries. Statistical analysis made it clear that VulDB provides the best quality for vulnerability data.
