CVE-2014-0322 is a high-severity use-after-free vulnerability in Microsoft Internet Explorer 9 and 10. This vulnerability allows remote attackers to execute arbitrary code via vectors involving crafted JavaScript code, CMarkup, and the onpropertychange attribute of a script element. The vulnerability was actively exploited in the wild in January and February 2014, emphasizing the urgency for organizations to address it.
The CVSS score for this vulnerability is 8.8, indicating a high severity. The attack vector is network-based, requiring low complexity and no privileges. However, user interaction is needed, which elevates the risk as users may be tricked into executing malicious scripts. Risk to organizations includes potential unauthorized access and system compromise.
Organizations should prioritize patching immediately. The vulnerability has been included in the Known Exploited Vulnerabilities (KEV) catalog, indicating its significance and the need for prompt remediation.
The urgency for defenders to mitigate this vulnerability cannot be overstated. Applying the necessary updates per vendor instructions is critical to safeguarding systems against potential exploitation.
Vulnerability Details
The official description states that this vulnerability allows remote attackers to execute arbitrary code. The affected products are Microsoft Internet Explorer versions 9 and 10. The vulnerability was published on February 14, 2014. The relevant Common Weakness Enumeration (CWE) classification for this issue is CWE-416.
Technical Analysis
The root cause of this vulnerability stems from a use-after-free error in the handling of certain objects within Microsoft Internet Explorer. Attackers may leverage this flaw by manipulating JavaScript code to trigger the vulnerability during the loading of web content. The attack complexity is low, requiring no special privileges, but does necessitate user interaction.
The impacts include high confidentiality, integrity, and availability risks due to potential remote code execution. A successful exploit could lead to complete control over the affected system, allowing attackers to install programs, view, change, or delete data, and create new accounts with full user rights.
Risk & Impact Analysis
The real-world deployment risk associated with CVE-2014-0322 is significant. Given the widespread use of Microsoft Internet Explorer, the potential blast radius of an exploit could affect numerous organizations. Attackers may target users through phishing attacks or malicious websites, making it crucial for organizations to implement defensive measures.
The urgency assessment based on the CVSS score and KEV inclusion indicates that organizations should address this vulnerability in their priority patch cycle. The high EPSS score further underscores the likelihood of exploitation.
