CVE-2013-1347 is a high-severity vulnerability affecting Microsoft Internet Explorer 8. This vulnerability allows remote attackers to execute arbitrary code by accessing an object that was either not properly allocated or has been deleted. The risk is compounded by the fact that this vulnerability was actively exploited in the wild as early as May 2013. Organizations using Internet Explorer 8 are urged to prioritize remediation.
The CVSS score for this vulnerability is 8.8, indicating a high severity level. This score reflects the potential impact on confidentiality, integrity, and availability, all rated as high. The vulnerability can be exploited through network vectors with low complexity, requiring no privileges but necessitating user interaction.
Risk to organizations includes potential unauthorized access to sensitive information and system integrity compromise. Given the nature of the vulnerability, organizations should prioritize patching immediately.
The urgency for defenders is critical, particularly given the known exploitation of the vulnerability and the high likelihood of future attacks if left unaddressed.
Vulnerability Details
The vulnerability description states that Microsoft Internet Explorer 8 does not properly handle objects in memory, allowing attackers to execute arbitrary code. The vulnerability falls under the CWE-416 classification, indicating a use-after-free flaw. This CVE was published on May 5, 2013, and remains relevant due to its continued exploitability.
Technical Analysis
The root cause of CVE-2013-1347 lies in the improper handling of memory objects. The attack vector is network-based, and the complexity of exploiting this vulnerability is low. Attackers require no privileges to initiate an attack, but user interaction is necessary, such as visiting a malicious web page.
The potential impact of this vulnerability is significant, leading to high confidentiality, integrity, and availability impacts. Organizations must implement security measures to mitigate these risks effectively.
Risk & Impact Analysis
Real-world deployment risk is high, with potential exploitation leading to significant data breaches or system compromises. The blast radius could extend to any user accessing compromised content, affecting not only individual systems but potentially entire networks.
Urgency assessment based on the CVSS score indicates that organizations should address this vulnerability in their priority patch cycle. The known exploitation status adds to the urgency, as failure to patch can lead to severe operational impacts.
