The year 2019 saw its fair share of significant vulnerabilities, and CVE-2019-1367 is one of them. This vulnerability affects the Microsoft Internet Explorer browser, specifically versions 9, 10, and 11, and it allows attackers to execute arbitrary code on the victim’s system. Here’s a deeper dive into this vulnerability, its implications, and some practical steps to mitigate its impact.
What is CVE-2019-1367?
CVE-2019-1367 refers to a remote code execution vulnerability in Microsoft Internet Explorer. This vulnerability exists in the way Internet Explorer handles objects in memory. An attacker could exploit this vulnerability by creating a specially crafted website designed to spur the vulnerability, and then convincing a user to view the website. The vulnerability could also be exploited through malicious advertisements on affected systems, leveraging the browser’s capability to render web pages to execute malicious code without any user interaction.
Impact of CVE-2019-1367
The exploitation of CVE-2019-1367 could lead to an attacker gaining the same privileges as the current user. If the current user is logged on with administrative user rights, an attacker could take control of the affected system, install programs, view, change, or delete data, or create new accounts with full user rights. This level of access poses significant risks, especially in environments where sensitive information is handled.
Mitigation Strategies
Patch Management: The most straightforward way to protect against CVE-2019-1367 is by ensuring that the latest security updates for Microsoft Internet Explorer are installed. Microsoft issued a patch for this vulnerability, which fixes the issue by modifying how Internet Explorer handles objects in memory.
Use of Alternative Browsers: Considering the vulnerability is specific to Internet Explorer, using alternative browsers like Google Chrome, Mozilla Firefox, or Microsoft Edge (which is not affected by this vulnerability) for browsing the internet can significantly reduce the risk of exploitation.
Enable Memory Protection: Features like Data Execution Prevention (DEP) and Address Space Layout Randomization (ASLR) can make it more difficult for an attacker to exploit this vulnerability successfully. Ensuring these features are enabled can provide an additional layer of protection.
Limit User Privileges: Implementing the principle of least privilege can reduce the impact of the vulnerability. If a user with limited privileges is exploited, the damage can be contained compared to an exploit happening under an account with administrative privileges.
Use of Exploit Protection Tools and Software Restrictions: Utilizing exploit protection tools and implementing software restriction policies can help detect and prevent the execution of malicious code. These tools can monitor system and application behavior for signs of exploit attempts and block them accordingly.
Conclusion
CVE-2019-1367 serves as a reminder of the importance of maintaining up-to-date software and employing a layered security approach. By understanding the risk posed by such vulnerabilities and taking proactive measures, individuals and organizations can protect themselves against exploitation. As the cybersecurity landscape continues to evolve, the need for vigilance and the adoption of best practices in vulnerability management will only continue to grow.
