Spring® Boot is a framework built on top of the Spring® Framework that simplifies the development of standalone, production-ready Spring® applications. It eliminates much of the boilerplate configuration required by traditional Spring® apps by offering auto-configuration, opinionated defaults, and embedded servers.
Spring® Boot Loader is a component of Spring® Boot responsible for launching Spring® Boot applications packaged as executable JARs or WARs. It enables developers to run their apps using java -jar without needing an external application server or classpath setup.
Authentication Bypass by Spoofing is an attack-focused weakness caused by incorrectly implemented authentication schemes that are subject to spoofing attacks. It can allow an attacker to access resources which are not otherwise accessible without proper authentication.
Improper Verification of Cryptographic Signature takes place when the product does not verify, or incorrectly verifies, the cryptographic signature for data. An attacker could gain access to sensitive data and possibly execute unauthorized code.
CVE-2024-38807 is a medium-severity vulnerability identified in Spring® Boot’s spring-boot-loader and spring-boot-loader-classic components. Specifically, applications that utilize these components and implement custom code for signature verification of nested JAR files may be susceptible to signature forgery. This means that content appearing to be signed by one entity could, in reality, have been signed by another, potentially allowing malicious code to be executed under the guise of trusted content.
This issue affects multiple versions of:
org.springframework.boot » spring-boot-loader package,
org.springframework.boot » spring-boot-loader-classic package.
