CVE-2012-0507 is a critical vulnerability affecting the Java Runtime Environment (JRE) component in multiple versions of Oracle Java SE, specifically versions 7 Update 2 and earlier, 6 Update 30 and earlier, and 5.0 Update 33 and earlier. This vulnerability allows remote attackers to execute arbitrary code, posing significant risks to organizations that rely on affected Java versions.
The CVSS score for this vulnerability is 9.8, indicating a critical severity level due to its potential to impact confidentiality, integrity, and availability. Attackers can exploit this vulnerability through network access with low complexity and without requiring user interaction, making it particularly dangerous.
Risk to organizations includes unauthorized access and potential system crashes, as the vulnerability may lead to denial of service. Organizations must prioritize patching this vulnerability immediately to safeguard their systems and data.
As of the latest information, this vulnerability is listed in the Known Exploited Vulnerabilities (KEV) catalog, indicating its active exploitation in the wild. Given the high profile of this vulnerability, organizations should act promptly to ensure they are protected.
Vulnerability Details
The vulnerability in question is tied to an unspecified issue within the Java Runtime Environment, which relates to concurrency handling. Specifically, it has been found that the AtomicReferenceArray class does not ensure that the array is of the Object[] type. This flaw allows attackers to cause a denial of service by crashing the Java Virtual Machine (JVM) or even bypassing Java sandbox restrictions.
This vulnerability was originally assigned to CVE-2011-3571, but that identifier was reassigned to a different issue. The vulnerability has significant implications for applications using the affected JRE versions.
The official description provided by Oracle states that this vulnerability allows remote attackers to affect confidentiality, integrity, and availability via unknown vectors related to concurrency. The absence of specific vectors makes it challenging to mitigate the risks without applying vendor patches.
The CVSS version 3.1 vector string for this vulnerability is CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H, confirming its critical impact across all three primary security domains.
Technical Analysis
The root cause of CVE-2012-0507 lies in the Java Runtime Environment's handling of concurrency within the AtomicReferenceArray class. Attackers can exploit this vulnerability through network access, with low complexity, and without requiring elevated privileges or user interaction.
In terms of impact, the attack can affect confidentiality, integrity, and availability, leading to potential unauthorized access and denial of service. As such, organizations should remain vigilant and apply patches to mitigate this risk.
Risk & Impact Analysis
The real-world deployment risk associated with CVE-2012-0507 is significant, particularly for organizations relying on older versions of Java SE. The potential for exploitation means that the blast radius could extend beyond the initial target, potentially impacting multiple systems relying on the affected JRE.
Given that this vulnerability is actively exploited, organizations must assess their current Java deployments and prioritize patching to avoid falling victim to an attack. The urgency for patching is critical, especially given the high CVSS score and known exploitation status.

Affected Versions
All versions prior to vendor patch are affected, specifically Java SE 7 Update 2 and earlier, 6 Update 30 and earlier, and 5.0 Update 33 and earlier. Additionally, various updates of the JRE component across platforms such as Debian, SUSE, and Oracle are impacted.
Mitigation & Remediation
Organizations should apply the latest patches from Oracle as soon as possible to mitigate the risks associated with CVE-2012-0507. It is critical to review internal systems and ensure that any instances of the affected Java Runtime Environment are updated to the latest secure versions.
In addition to patching, organizations should consider implementing additional security measures, such as network controls and monitoring to detect unusual activity. For comprehensive coverage, organizations may also benefit from penetration testing to validate the effectiveness of security controls.
Detection Guidance
Organizations should monitor logs for any indicators of exploitation or unusual behavior related to the Java Runtime Environment. Key indicators may include unexpected application crashes, unusual network traffic patterns, or unauthorized access attempts. Implementing behavioral analysis can also help in identifying potential compromises.
