CVE-2024-21574 is a critical vulnerability affecting the ComfyUI Manager, stemming from a missing validation of the pip field in a POST request to the /customnode/install endpoint. This vulnerability allows attackers to craft requests that trigger a pip install on user-controlled packages or URLs, resulting in remote code execution (RCE) on the server. The CVSS score of 10 indicates the severity and potential impact of this vulnerability.
Organizations utilizing ComfyUI Manager must recognize that this vulnerability exposes their systems to significant risks. The ability for an attacker to execute arbitrary code on the server can lead to unauthorized access and data breaches. As such, organizations should prioritize patching immediately to safeguard their environments from potential exploitation.
As of now, the vulnerability is classified as awaiting analysis, which highlights the urgency for organizations to remain vigilant and proactive in their security posture. The risk to organizations includes compromising sensitive data and disrupting operational integrity.
Given the critical nature of this vulnerability and its potential for exploitation, organizations should ensure that they are prepared to respond to any security incidents related to CVE-2024-21574. This involves monitoring for unusual activities and ensuring that all relevant security controls are in place.
Vulnerability Details
The issue stems from a missing validation of the pip field in a POST request sent to the /customnode/install endpoint. This endpoint is used to install custom nodes which are added to the server by the extension. The lack of validation allows an attacker to craft a request that triggers a pip install on a user-controlled package or URL, leading to remote code execution (RCE) on the server.
The CVSS score for this vulnerability is 10, indicating a critical severity level. This score reflects the potential impact of the vulnerability on confidentiality, integrity, and availability. The vulnerability is associated with CWE-94, which pertains to code injection vulnerabilities.
The vulnerability was published on December 12, 2024, and is currently awaiting analysis. Organizations using affected systems should prepare for potential remediation measures.
Technical Analysis
The root cause of CVE-2024-21574 is the absence of input validation in the POST request to the /customnode/install endpoint. The attack vector is network-based, and the attack complexity is low, meaning that an attacker can exploit this vulnerability without significant effort.
No privileges are required for exploitation, and user interaction is not necessary. The vulnerability has a high confidentiality impact, integrity impact, and availability impact, as successful exploitation could allow an attacker to control the affected server completely.
Risk & Impact Analysis
Risk to organizations includes unauthorized access to server resources, potential data breaches, and disruption of services. The blast radius for this vulnerability is significant, as it affects any server utilizing the vulnerable endpoint, potentially impacting multiple users and systems.
Given the CVSS score of 10, organizations should prioritize patching immediately. The urgency for remediation is critical, especially for high-profile targets or organizations handling sensitive data.
