Background
Quarkus is a Java framework designed for building cloud-native applications. It provides a lightweight and efficient runtime that enables developers to create highly performant and scalable applications. The Quarkus HTTP component is responsible for handling HTTP requests and enforcing security policies. However, a vulnerability has been discovered in the HTTP security policies of Quarkus, which can lead to incorrect evaluation of permissions.
Vulnerability Detail
The vulnerability in Quarkus HTTP arises from the incorrect sanitization of certain character permutations in incoming requests. This flaw allows an attacker to bypass the security policy and gain unauthorized access to endpoints. Additionally, it could potentially result in a denial of service if the attacker exploits the vulnerability to overload the system with unauthorized requests. The impact of this vulnerability is significant, as it undermines the integrity and security of the application.
How To Fix
Fixed versions by release line
The minimum fixed version depends on the release line you run.

Workaround
As a workaround, until the packages can be updated, it is recommended to implement additional security measures such as input validation and request filtering to mitigate the risk of unauthorized access. By carefully validating and sanitizing incoming requests, the impact of the vulnerability can be reduced. Here is an example of how to implement input validation in Java:
public boolean validateInput(String input) {
// Perform input validation logic here
// Return true if input is valid, false otherwise
}
Conclusion
The vulnerability in Quarkus HTTP can have severe consequences, including unauthorized access and potential denial of service. It is crucial to update the affected packages to the secure versions mentioned in the 'how_to_fix' section. Implementing additional security measures, as described in the 'workaround' section, can provide temporary protection until the packages are updated.
