Oracle Java SE/JRE AtomicReferenceArray Sandbox 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.

A vulnerability was found in Oracle Java SE and JRE (Programming Language Software) (affected version not known) and classified as very critical. Affected by this issue is some unknown functionality of the component AtomicReferenceArray Sandbox. The manipulation with an unknown input leads to a memory corruption vulnerability. Using CWE to declare the problem leads to 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. Impacted is confidentiality, integrity, and availability. CVE summarizes:

Unspecified vulnerability in the Java Runtime Environment (JRE) component in Oracle Java SE 7 Update 2 and earlier, 6 Update 30 and earlier, and 5.0 Update 33 and earlier allows remote attackers to affect confidentiality, integrity, and availability via unknown vectors related to Concurrency. NOTE: the previous information was obtained from the February 2012 Oracle CPU. Oracle has not commented on claims from a downstream vendor and third party researchers that this issue occurs because the AtomicReferenceArray class implementation does not ensure that the array is of the Object[] type, which allows attackers to cause a denial of service (JVM crash) or bypass Java sandbox restrictions. NOTE: this issue was originally mapped to CVE-2011-3571, but that identifier was already assigned to a different issue.

The bug was discovered 01/17/2012. The weakness was published 02/14/2012 with Oracle (Website). The advisory is shared for download at blogs.technet.com. This vulnerability is handled as CVE-2012-0507 since 01/11/2012. The attack may be launched remotely. A simple authentication is required for exploitation. Technical details are unknown but a public exploit is available. The current price for an exploit might be approx. USD $0-$5k (estimation calculated on 04/23/2024). This vulnerability has a historic impact due to its background and reception.

A public exploit has been developed by metasploit in Java and been published 2 months after the advisory. The exploit is available at exploit-db.com. It is declared as highly functional. The vulnerability was handled as a non-public zero-day exploit for at least 28 days. During that time the estimated underground price was around $100k and more. A worm is spreading, which is automatically exploiting this vulnerability. The vulnerability scanner Nessus provides a plugin with the ID 802947 , which helps to determine the existence of the flaw in a target environment. The commercial vulnerability scanner Qualys is able to test this issue with plugin 185006 (HP-UX Running Java Remote Unauthorized Access Vulnerability (HPSBUX02784)). This issue was added on 03/03/2022 to the CISA Known Exploited Vulnerabilities Catalog with a due date of 03/24/2022:

Apply updates per vendor instructions.

Applying a patch is able to eliminate this problem. A possible mitigation has been published immediately after the disclosure of the vulnerability. Attack attempts may be identified with Snort ID 21438. Furthermore it is possible to detect and prevent this kind of attack with TippingPoint and the filter 12771.

The vulnerability is also documented in the databases at X-Force (72513), Tenable (802947) and Exploit-DB (18679). news.drweb.com is providing further details.
