Researchers on Tuesday found a denial-of-service (DoS) vulnerability in Eclipse Jetty, a widely-used open source web server and servlet container.


In a blog post, Synopsys Cybersecurity Research Center (CyRC) researchers said while they have not observed memory leaks or crashes because of CVE-2020-27223, a server may take minutes to process a single request. Researchers also observed an exponential relationship between the size of the request and the duration of CPU use.


According the Eclipse Foundation’s website: “Jetty is used in a wide variety of projects and products, both in development and production. Jetty has long been loved by developers due to its long history of being easily embedded in devices, tools, frameworks, application servers, and modern cloud services.”


Because Jetty has such wide use, Dirk Schrader, global vice president of security research at New Net Technologies, called this vulnerability something close to a digital nightmare. Schrader said especially on embedded devices in industrial control systems – which are often not patchable – this can have severe consequences as availability has become paramount in IoT environments.
