Sun Solaris 10.0 Kernel sysinfo integer coercion

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 Sun Solaris 10.0 (Operating System). It has been classified as critical. This affects the function sysinfo of the component Kernel. The manipulation with an unknown input leads to a integer coercion vulnerability. CWE is classifying the issue as CWE-192. Integer coercion refers to a set of flaws pertaining to the type casting, extension, or truncation of primitive data types. This is going to have an impact on confidentiality. The summary by CVE is:

systeminfo.c for Sun Solaris allows local users to read kernel memory via a 0 variable count argument to the sysinfo system call, which causes a -1 argument to be used by the copyout function. NOTE: this issue has been referred to as an integer overflow, but it is probably more like a signedness error or integer underflow.

The bug was discovered 07/20/2006. The weakness was released 07/24/2006 with iDEFENSE (Website). It is possible to read the advisory at sunsolve.sun.com. This vulnerability is uniquely identified as CVE-2006-3824 since 07/24/2006. The attack needs to be initiated within the local network. No form of authentication is needed for exploitation. Technical details and a public exploit are known.

A public exploit has been developed in ANSI C and been published even before and not after the advisory. The exploit is shared for download at prdelka.blackart.org.uk. It is declared as functional. The vulnerability was handled as a non-public zero-day exploit for at least 536 days. During that time the estimated underground price was around $5k-$25k. The commercial vulnerability scanner Qualys is able to test this issue with plugin 115381 (Sun Solaris SysInfo Local Information Disclosure Vulnerability).

Applying a patch is able to eliminate this problem. The bugfix is ready for download at sunsolve.sun.com. A possible mitigation has been published even before and not after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at X-Force (27901), Exploit-DB (2067), SecurityFocus (BID 19104†), OSVDB (27438†) and Secunia (SA21148†). Entries connected to this vulnerability are available at VDB-2392, VDB-2389, VDB-2388 and VDB-2390. Statistical analysis made it clear that VulDB provides the best quality for vulnerability data.
