This vulnerability allows a type confusion issue in the mpath package, specifically affecting versions prior to 0.8.4. It can lead to a bypass of CVE-2018-16490. The identified condition ignoreProperties.indexOf(parts[i]) !== -1 returns -1 if parts[i] is ['__proto__']. This results from the method being called, which is Array.prototype.indexOf() for arrays, rather than String.prototype.indexOf(). This discrepancy in behavior based on input type poses a risk.
The severity of this vulnerability is classified as medium with a CVSS score of 5.6. This score indicates a moderate risk level, generally suggesting that organizations should address this vulnerability in their patch cycles.
Risk to organizations includes potential exploitation that could lead to unauthorized access or manipulation of data, thereby compromising system integrity.
As there are currently no known exploits available for this vulnerability, organizations can take proactive measures to mitigate potential risks. Organizations should prioritize patching immediately.
Understanding the nature of this vulnerability and its implications is critical for maintaining secure environments.
Vulnerability Details
The mpath package is affected by a type confusion vulnerability that can lead to a bypass of CVE-2018-16490. The vulnerability is classified as CWE-843.
The CVSS score from Snyk is 5.6, reflecting a medium severity level, while the NVD lists a CVSS score of 9.8, indicating a critical severity level. The discrepancy between these scores highlights the importance of understanding the context in which the vulnerability exists.
The vulnerability affects versions of mpath prior to 0.8.4, with a publication date of September 1, 2021.
Technical Analysis
The root cause of this vulnerability is a type confusion issue in the mpath package. This occurs when the method Array.prototype.indexOf() is called on an array instead of a string, leading to unintended behavior when the input is of varying types.
The attack vector for this vulnerability is network-based, allowing potential exploitation without requiring physical access to the target system.
The attack complexity is classified as high, meaning that successful exploitation may require specific conditions or knowledge about the target system. No privileges are required for exploitation, and user interaction is not necessary.
The confidentiality, integrity, and availability impacts are all low, indicating that while the risks are present, the potential for significant damage is limited under normal circumstances.
Risk & Impact Analysis
Organizations using the mpath package should consider the real-world implications of this vulnerability. The potential for bypassing existing security controls (like CVE-2018-16490) could expose sensitive data or allow unauthorized actions.
The urgency for remediation is categorized as medium, suggesting organizations should schedule patching within their normal maintenance cycles. However, if the mpath package is critical to business operations, immediate action may be warranted.
Given the potential attack vector across the network, the blast radius could extend widely, impacting any systems utilizing the vulnerable package.
