CVE-2020-1380 is a high-severity remote code execution vulnerability affecting Microsoft Internet Explorer. This vulnerability allows an attacker to execute arbitrary code in the context of the current user, potentially leading to full control over the affected system, especially when the user has administrative rights. The vulnerability arises from how the scripting engine manages objects in memory, which can be exploited through various means, including specially crafted websites or malicious Office documents.
The potential impact is significant, as an attacker could install programs, view or delete data, and create new user accounts with full rights. Given the exploitation possibilities, organizations must prioritize remediation efforts to safeguard their systems against this threat.
Microsoft released a security update addressing this vulnerability, modifying how the scripting engine handles objects in memory. Organizations should apply these updates immediately to mitigate the associated risks.
As of now, there are no confirmed public exploits available for CVE-2020-1380, but the high exploitation potential necessitates vigilance and prompt action from security teams.
Vulnerability Details
The vulnerability allows for remote code execution due to improper handling of objects in memory in Internet Explorer's scripting engine. The CVSS score is 7.8, indicating a high severity level.
The affected product is Internet Explorer 11. This vulnerability is classified under CWE-787, which pertains to improper access of memory locations.
Technical Analysis
The root cause of CVE-2020-1380 lies in the scripting engine’s management of objects in memory. Attackers can exploit this vulnerability through local access or via the network, particularly by convincing users to visit compromised or malicious websites.
The attack complexity is low, and the privileges required by the attacker are also low, meaning that even users with minimal access can exploit the vulnerability if they interact with the malicious content. User interaction is necessary, as the attack relies on the target being tricked into visiting the malicious site.
If successfully exploited, the impacts on confidentiality, integrity, and availability are all high, as an attacker could execute arbitrary code, potentially leading to full system compromise.
Risk & Impact Analysis
Organizations face significant risk from CVE-2020-1380 due to the high potential for exploitation. The vulnerability can be leveraged in web-based attacks, making any organization using Internet Explorer particularly vulnerable. The urgency for remediation is critical, especially for users with administrative rights.
The high CVSS score of 8.8 indicates that organizations should treat this vulnerability as a priority. The blast radius could be extensive, affecting systems across networks if exploited effectively.
Given that CVE-2020-1380 is part of the Known Exploited Vulnerabilities (KEV) catalog, organizations must act swiftly to apply the necessary security updates and mitigate potential risks.
