Sun Solaris 7.0/8.0/9.0/10.0 on x86 Hyper-Threading 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.

A vulnerability classified as critical has been found in Sun Solaris 7.0/8.0/9.0/10.0 on x86 (Operating System). This affects some unknown processing of the component Hyper-Threading Handler. 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, integrity, and availability. The summary by CVE is:

Hyper-Threading technology, as used in FreeBSD and other operating systems that are run on Intel Pentium and other processors, allows local users to use a malicious thread to create covert channels, monitor the execution of other threads, and obtain sensitive information such as cryptographic keys, via a timing attack on memory cache misses.

The bug was discovered 03/04/2005. The weakness was shared 06/02/2005 by Colin Percival (Website). It is possible to read the advisory at sunsolve.sun.com. This vulnerability is uniquely identified as CVE-2005-0109 since 01/18/2005. Access to the local network is required for this attack to succeed. 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 T1592 according to MITRE ATT&CK.

It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 1 days. During that time the estimated underground price was around $5k-$25k. The vulnerability scanner Nessus provides a plugin with the ID 20522 (Ubuntu 4.10 / 5.04 : linux-source-2.6.8.1, linux-source-2.6.10 vulnerabilities (USN-131-1)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Ubuntu Local Security Checks and running in the context l. The commercial vulnerability scanner Qualys is able to test this issue with plugin 117897 (CentOS Security Update for OpenSSL (CESA-2005:476)).

Applying a patch is able to eliminate this problem. The bugfix is ready for download at sun.com. A possible mitigation has been published before and not just after the disclosure of the vulnerability. Furthermore it is possible to detect and prevent this kind of attack with TippingPoint and the filter 3342.

The vulnerability is also documented in the databases at X-Force (19971) and Tenable (20522). The entries 950, 1477 and 24996 are related to this item.
