CVE-2020-0968 is a remote code execution vulnerability that exists in the way the scripting engine handles objects in memory in Microsoft Internet Explorer. This vulnerability has been classified as high severity with a CVSS score of 7.5, indicating a significant risk to organizations utilizing affected versions of Internet Explorer.
The exploitation of this vulnerability could allow attackers to execute arbitrary code on the affected system. This means that if an attacker successfully exploits this vulnerability, they could potentially gain unauthorized access to sensitive information or execute harmful actions on the compromised system.
Organizations should prioritize patching this vulnerability immediately. Ensuring that the latest updates are applied can significantly reduce the risk of exploitation by attackers.
The vulnerability was publicly disclosed on April 15, 2020, and has been included in the Known Exploited Vulnerabilities (KEV) catalog, indicating that it is actively being targeted by attackers.
As a defensive measure, organizations are advised to monitor network traffic for any suspicious activity related to Internet Explorer and to implement appropriate security controls to mitigate potential attacks.
Given the nature of this vulnerability and its potential impact, it is crucial for organizations to remain vigilant and proactive in their security posture.
Vulnerability Details
The vulnerability, known as the 'Scripting Engine Memory Corruption Vulnerability,' allows for remote code execution due to improper handling of objects in memory. The CVSS score of 7.5 indicates a high severity level, emphasizing the urgency for remediation.
This vulnerability specifically affects Microsoft Internet Explorer version 11 and 9. Organizations using these versions should ensure that they apply the necessary patches to mitigate the risk.
Published on April 15, 2020, this vulnerability has been classified under CWE-787, indicating a memory corruption issue.
Technical Analysis
The root cause of CVE-2020-0968 lies in the scripting engine's failure to properly manage memory objects. As a result, an attacker could exploit this vulnerability via crafted web content, requiring user interaction to trigger the exploit, which significantly increases the attack complexity.
The attack vector is classified as network-based, meaning an attacker can exploit this vulnerability remotely without physical access to the system. The required privileges to exploit this vulnerability are none, but user interaction is required to initiate the attack.
The impacts of this vulnerability are severe, affecting confidentiality, integrity, and availability, all rated as high.
Risk & Impact Analysis
Risk to organizations includes potential unauthorized access to sensitive information and system control. The blast radius could be significant, affecting all users interacting with the vulnerable versions of Internet Explorer.
Given the high CVSS score, organizations should assess their exposure and prioritize remediation efforts. The EPSS score of 0.436730000 indicates a high probability of exploitation in the wild, further emphasizing the urgency of addressing this vulnerability.
Organizations should implement network segmentation and monitoring to detect potential exploitation attempts, alongside regular security assessments to identify other vulnerabilities.
