CVE-2022-25893 refers to a critical vulnerability in the vm2 package, specifically versions prior to 3.9.10. This vulnerability allows for arbitrary code execution due to the usage of prototype lookup for the WeakMap.prototype.set method. Exploiting this vulnerability leads to access to a host object and a sandbox compromise. With a CVSS score of 9.8, the severity of this vulnerability cannot be understated.
Risk to organizations includes potential unauthorized access to sensitive data and complete control over the affected system. Given the high CVSS score, organizations should prioritize patching immediately. Currently, there are no known exploits available for this vulnerability, but the potential impact remains critical.
The urgency for defenders is high as the exploitability of this vulnerability is classified as critical. Organizations utilizing affected versions of the vm2 package should take urgent action to mitigate the risk by upgrading to the latest version.
In summary, CVE-2022-25893 poses a significant threat to organizations that have not yet upgraded their vm2 package. Immediate attention to this vulnerability is required to safeguard systems.
Vulnerability Details
The package vm2 before version 3.9.10 is vulnerable to arbitrary code execution due to the usage of prototype lookup for the WeakMap.prototype.set method. Exploiting this vulnerability enables attackers to access a host object and compromise the sandbox environment.
The CVSS score for this vulnerability is 9.8, categorized as critical. This high score indicates a severe risk to confidentiality, integrity, and availability of systems utilizing the affected versions.
CWE-471 is the identified weakness related to this vulnerability, which signifies the potential for insecure handling of object prototypes.
This vulnerability was published on December 21, 2022, and has since been modified. Organizations using the vm2 package should take immediate steps to upgrade to version 3.9.10 or later.
Technical Analysis
The root cause of this vulnerability lies in the improper usage of prototype lookups for managing WeakMap instances, allowing unauthenticated users to manipulate the prototype chain and execute arbitrary code. The attack vector for this vulnerability is network-based, meaning an attacker only needs to have network access to the application utilizing the vulnerable package.
The attack complexity is considered low, with no privileges required for exploitation. User interaction is not needed, allowing attackers to exploit the vulnerability easily. The impacts on confidentiality, integrity, and availability are all rated as high, indicating that successful exploitation can lead to significant harm.
Risk & Impact Analysis
The risk associated with CVE-2022-25893 is substantial, as it allows for arbitrary code execution within the application context. Organizations running the affected versions of vm2 may experience unauthorized access, data exfiltration, and potential complete system compromise.
This vulnerability has a broad blast radius due to its critical nature and the potential for widespread exploitation across various applications that utilize the vm2 package. Organizations are urged to assess their deployment and prioritize patching based on the severity of this vulnerability.
Given the critical CVSS score and current lack of known exploits, organizations should still treat this vulnerability as a high priority in their remediation efforts. The exploitation status indicates no known public exploits, but the risk remains high.
