The Cyble Security Update Advisory has recently released a report focusing on the latest vulnerabilities and patches from various vendors.
The report highlighted several critical security flaws in the popular JavaScript library, vm2. This library is widely used for sandboxing untrusted code execution in Node.js environments.
These vulnerabilities allow attackers to cause an unsanitized host exception, eventually leading to the execution of arbitrary code in the host context and breaking out of the sandbox.
JavaScript Library vm2 vulnerabilities
The report has categorized these vulnerabilities as High, Medium, and Low based on the severity standards defined by the Common Vulnerability Scoring System (CVSS).
It indicates two critical vulnerabilities in the vm2 library, with a TLP rating of AMBER.
The CVE ID(s) for these vulnerabilities are CVE-2023-29199 and CVE-2023-30547.
The report explains that the Remote Code Execution Vulnerability (CVE-2023-29199) has a CVSSv3.1 score of 9.8, while the Arbitrary Code Execution Vulnerability (CVE-2023-30547) also has a CVSSv3.1 score of 9.8.
These vulnerabilities are considered critical and affect versions of vm2 up to 3.9.16.
The report further details the vulnerability in the source code transformer, specifically in the exception sanitization logic.
Attackers can bypass the handleException() function and reveal unsanitized host exceptions, ultimately leading to remote code execution privileges.
As a result, users of the vm2 library need to update their systems to the latest version to stay protected against potential attacks.
Keeping software up-to-date and applying patches promptly can help mitigate the risk of security breaches.
The vm2 library is widely used in various industries, including finance, healthcare, and e-commerce.
Therefore, it is crucial to understand the impact of these vulnerabilities and take necessary measures to ensure that your systems are protected.
Conclusion
The Cyble Security Update Advisory highlights the critical vulnerabilities in the vm2 JavaScript library, which can lead to remote code execution.
It is crucial to stay up-to-date with security patches and updates for all software components to minimize the risk of potential security breaches.
Organizations should take necessary measures to protect their systems and stay informed of the latest updates and vulnerabilities.
By taking proactive steps, organizations can mitigate the risk of security breaches and protect their valuable data and assets.
