CVE-2022-4147 is a high-severity vulnerability affecting the Quarkus framework. This vulnerability allows simple GET and POST requests with invalid Origin headers to proceed, potentially leading to unauthorized access to sensitive resources. The assessed CVSS score for this vulnerability is 7.5, indicating a high level of concern that organizations must address to safeguard their applications.
The risk to organizations includes the possibility of unauthorized actions being performed on behalf of legitimate users, which can lead to significant data breaches or service disruptions. The vulnerability impacts applications that utilize Quarkus for handling CORS, making it essential for developers and security teams to prioritize remediation efforts.
Currently, there is no known exploit publicly available for this vulnerability, but the potential impact remains substantial. Organizations should prioritize patching immediately to prevent exploitation.
The vulnerability was published on December 6, 2022, and has been classified as modified in the CVE database. It is crucial for organizations utilizing Quarkus to assess their exposure and implement necessary updates promptly.
Vulnerability Details
According to the CVE description, the Quarkus CORS filter permits simple GET and POST requests with invalid Origin headers. These requests, made using XMLHttpRequest without registered event listeners or ReadableStream objects, can allow unauthorized actions to be executed.
This vulnerability falls under the CWE-1026 classification, indicating a weakness in the design of the CORS filter. Organizations should be aware of the potential risks associated with the configuration and design of their web applications.
The CVSS score of 7.5 reflects the high impact this vulnerability can have on confidentiality, integrity, and availability. The attack vector is classified as network-based, and the attack complexity is high, requiring user interaction. This means that while the vulnerability is serious, exploiting it may not be straightforward.
Technical Analysis
The root cause of this vulnerability lies in the implementation of the CORS filter in Quarkus. Attackers may leverage this flaw to bypass security measures intended to prevent unauthorized access to resources. The attack vector is primarily network-based, allowing remote attackers to exploit vulnerable configurations.
Given that the attack complexity is high and user interaction is required, attackers must convince users to perform specific actions, such as clicking on malicious links or executing scripts designed to exploit the vulnerability.
The confidentiality, integrity, and availability impacts are assessed as high, indicating that successful exploitation can lead to significant data exposure and unauthorized modifications, potentially affecting the availability of the application.
Risk & Impact Analysis
Real-world deployment of this vulnerability poses a serious risk, especially for organizations using Quarkus in environments where sensitive data is accessible. The potential blast radius is substantial due to the widespread use of web applications leveraging CORS for cross-origin requests.
Organizations should address this vulnerability in their priority patch cycle to mitigate risks associated with unauthorized access and data breaches. Given the high CVSS score, the urgency for remediation is critical.
