Background
Jetty8 is a Java servlet engine and webserver. It provides a platform for running Java-based web applications and serving HTTP requests. The package is widely used in various web applications and services. However, a vulnerability has been discovered in Jetty8 that could potentially expose cryptographic credentials, such as passwords, to a local user.
Vulnerability Detail
The vulnerability in Jetty8 is a timing attack that allows a local user to gain access to sensitive cryptographic credentials. By exploiting timing differences in the execution of certain operations, an attacker can deduce the values of cryptographic credentials, including passwords. This can lead to unauthorized access to systems and compromise the security of the affected application or service.
