CVE-2022-21449 "Psychic Signatures": Analyzing the New Java Crypto Vulnerability

A few days ago, security researcher Neil Madden published a blog post, in which he provided details about a newly disclosed vulnerability in Java, CVE-2022-21449 or “Psychic Signatures”. This security vulnerability originates in an improper implementation of the ECDSA signature verification algorithm, introduced in Java 15.

Just Because You Don't Use Log4j or Spring Beans Doesn't Mean Your Application is Unaffected

By now, you’re probably all aware of the recent Log4j and Spring Framework vulnerabilities. As a recap, the Log4j vulnerability – made public on December 10, 2021 – was the result of an exploitable logging feature that, if successfully exploited, could allow attackers to perform an RCE (Remote Code Execution) and compromise the affected server.

Java Spring vulnerabilities

Several vulnerabilities for Java Spring framework have been disclosed in the last hours and classified as similar as the vulnerability that caused the Log4Shell incident at the end of 2021. However, as of the publishing of this report, the still ongoing disclosures and events on these vulnerabilities suggest they are not as severe as their predecessor.

Two RCE Vulnerabilities Found in Spring Framework

At the end of March 2022, two critical vulnerabilities (CVE-2022-22963 and CVE-2022-22965) were discovered in different components of VMware Spring. Spring is a popular framework focused on facilitating the development of Java applications, including cloud-based apps, eliminating the need for additional code or concerns related to server requirements.

What's Next for Log4j: Tales from the Trenches

The recently discovered flaw in Apache’s popular open source logging library for Java, Log4j, could wreak havoc for years to come. Analysts are predicting it could take as long as five years to finish patching related security flaws because of the widespread adoption of the logging library and the complexity involved in maintaining third-party software libraries.

The Next Log4Shell? Spring4Shell Hitting Waves.

A new vulnerability was found in the Spring Core module of the Spring Framework. This was discovered by a Chinese security researcher, posting a Proof-of-Concept (POC) on GitHub (Figure 1), which later was deleted. This vulnerability is a zero-day, which currently wasn’t assigned a CVE, and was dubbed by security researchers as “Spring4Shell” or “SpringShell”, after the recent vulnerability in the Log4j Java package, discovered last December, and made waves worldwide.
