CVE-2023-45311 is a critical vulnerability in the fsevents project that affects versions before 1.2.11. This vulnerability allows an adversary to execute arbitrary code if any JavaScript project that depends on fsevents distributes code obtained from a specific URL at a time when it was controlled by an adversary. The severity of this vulnerability is underscored by its CVSS score of 9.8, indicating a critical risk level.
Risk to organizations includes potential unauthorized access and manipulation of sensitive data, as the arbitrary code execution could lead to further exploitation. Given its nature, organizations should prioritize patching immediately.
Currently, there is no public exploit confirmed for this vulnerability, and it is not listed in the Known Exploited Vulnerabilities (KEV) catalog. However, the implications of this vulnerability necessitate immediate attention.
In conclusion, organizations using the fsevents package should act swiftly to mitigate potential risks associated with this vulnerability.
Vulnerability Details
The fsevents project, specifically versions earlier than 1.2.11, has a vulnerability due to dependency on a URL that could be controlled by an adversary. The official CVE description states that this vulnerability allows arbitrary code execution when projects distribute code obtained from the affected URL.
The vulnerability is classified under CWE-94, which pertains to Code Injection. With a CVSS score of 9.8, it falls into the critical severity category. This vulnerability affects all versions of fsevents prior to the patched version 1.2.11, published on October 6, 2023.
Technical Analysis
The root cause of this vulnerability is the reliance on an external URL that might be manipulated by adversaries. The attack vector is network-based, and the complexity of the attack is low, meaning that attackers do not need elevated privileges or user interaction to exploit this vulnerability. The impacts on confidentiality, integrity, and availability are all high, making this a significant risk for organizations.
Risk & Impact Analysis
Organizations using vulnerable versions of fsevents face substantial risks, including unauthorized access and manipulation of data. The potential blast radius is considerable, as many JavaScript projects may rely on fsevents. Given the critical nature of this vulnerability, organizations should assess their exposure and prioritize remediation efforts accordingly.
