CVE-2021-23403 represents a high-severity vulnerability that affects all versions of the ts-nodash package. This vulnerability allows for prototype pollution via the Merge() function due to a lack of input validation. The implications of this vulnerability are significant, as it poses a risk to the integrity of the affected software. With a CVSS score of 7.3, organizations utilizing this package should take immediate action.
The vulnerability was published on July 2, 2021, and has since been classified as having high exploitability potential. This means that attackers may leverage this vulnerability to execute unauthorized actions, potentially leading to severe impacts on confidentiality, integrity, and availability.
Organizations should prioritize patching immediately to prevent any potential exploitation. The urgency is underscored by the commonality of the ts-nodash package in applications, warranting prompt remediation efforts.
Given the nature of the vulnerability and the potential for exploitation, security practitioners must assess their environments for the presence of the ts-nodash package and ensure that appropriate patches are applied without delay.
Vulnerability Details
The vulnerability affects all versions of the ts-nodash package and is characterized by prototype pollution through the Merge() function due to insufficient validation of input. The CVSS score from the NVD is 9.8, indicating a critical severity level under CVSS 3.1 standards. The vulnerability is documented under CWE-1321, which highlights the specific weakness associated with prototype pollution.
Technical Analysis
The root cause of this vulnerability lies in the Merge() function not properly validating input before processing. This oversight allows for the modification of an object's prototype, leading to potential manipulation of properties and methods. The attack vector is network-based, with a low attack complexity, meaning that exploitation can occur without sophisticated techniques. Importantly, no privileges are required, and user interaction is not needed for an attack to succeed.
The impacts of this vulnerability include low confidentiality, integrity, and availability impacts, though they can escalate if exploited in conjunction with other vulnerabilities or misconfigurations.
Risk & Impact Analysis
The real-world risk associated with CVE-2021-23403 is considerable, given the widespread use of the ts-nodash package in various applications. If exploited, the blast radius could extend significantly, impacting not just the application in which the vulnerability resides but potentially other integrated systems as well.
Organizations must understand that the potential for exploitation necessitates a proactive approach to security. The urgency is high due to the critical nature of the vulnerability as classified by the CVSS score. Organizations should address this vulnerability in their priority patch cycle to mitigate risks effectively.
