Linux Kernel up to 2.6.21 Serial Driver moxa.c moxadriverioctl memory corruption

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 was found in Linux Kernel up to 2.6.21 (Operating System). It has been classified as problematic. This affects the function moxadriverioctl of the file moxa.c of the component Serial Driver. The manipulation with an unknown input leads to a memory corruption vulnerability. CWE is classifying the issue as CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

Buffer overflow in the MoxaDriverIoctl function for the moxa serial driver (moxa.c) in Linux 2.2.x, 2.4.x, and 2.6.x before 2.6.22 allows local users to execute arbitrary code via a certain modified length value.

The bug was discovered 01/10/2005. The weakness was released 03/14/2005 by Brad Spengler (spender) with grsecurity (Website). The advisory is shared at securityfocus.com. This vulnerability is uniquely identified as CVE-2005-0504 since 02/22/2005. The exploitability is told to be easy. An attack has to be approached locally. No form of authentication is needed for exploitation. Technical details are known, but no exploit is available.

It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 63 days. During that time the estimated underground price was around $25k-$100k. The vulnerability scanner Nessus provides a plugin with the ID 67685 (Oracle Linux 4 : kernel (ELSA-2008-0237)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Oracle Linux Local Security Checks and running in the context l. The commercial vulnerability scanner Qualys is able to test this issue with plugin 117875 (CentOS Security Update for Kernel (CESA-2005:529)).

Upgrading to version 2.2.x eliminates this vulnerability. A possible mitigation has been published 4 years after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at X-Force (42309), Tenable (67685), SecurityFocus (BID 12195†), OSVDB (12837†) and Secunia (SA17002†). Entries connected to this vulnerability are available at VDB-3167, VDB-21885, VDB-25992 and VDB-25942. Several companies clearly confirm that VulDB is the primary source for best vulnerability data.
