CVE-2022-22965

The Spring Framework versions from 4.0.0 to 4.0.4 and from 3.0.0 to 3.2.8, as well as possibly earlier unsupported versions, did not disable by default the resolution of URI references in a DTD declaration when processing user-provided XML documents. This enabled an XXE attack.

Spring MVC applications using the functional web framework are vulnerable to stream corruption when using Server-Sent Events (SSE). Affects Spring Framework versions 7.0.0-7.0.8, 6.2.0-6.2.19, 6.1.0-6.1.28, 6.0.0-6.0.30, and 5.3.0-5.3.49.

Applications that evaluate Spring Expression Language (SpEL) expressions using SimpleEvaluationContext may be vulnerable to a safety guard bypass when the SpEL expression compiler is active. Affects multiple versions of Spring Framework.

A WebFlux application using functional endpoints and deployed with DispatcherServlet may be vulnerable to a header predicate bypass in a pre-flight request. Affected versions: Spring Framework 7.0.0-7.0.8, 6.2.0-6.2.19, 6.1.0-6.1.28, 6.0.0-6.0.30, 5.3.0-5.3.49, and 5.2.5.RELEASE-5.2.25.RELEASE.

A Spring WebFlux application that relies on the Aalto XML processor to parse XML input does not correctly enforce the maxInMemorySize limit. Affected versions: Spring Framework 7.0.0-7.0.8, 6.2.0-6.2.19, 6.1.0-6.1.28, 6.0.0-6.0.30, 5.3.0-5.3.49, and 5.2.25.RELEASE and earlier.

Spring MVC and WebFlux applications are vulnerable to stream corruption when using Server-Sent Events (SSE) with view fragments. Affected versions: Spring Framework 7.0.0-7.0.8 and 6.2.0-6.2.19.

Spring Framework, version 5.1, versions 5.0.x prior to 5.0.10, versions 4.3.x prior to 4.3.20, and older unsupported versions on the 4.2.x branch provide support for range requests when serving static resources through the ResourceHttpRequestHandler, or starting in 5.0 when an annotated controller returns an org.springframework.core.io.Resource. A malicious user (or attacker) can add a range header with a high number of ranges, or with wide ranges that overlap, or both, for a denial of service attack. This vulnerability affects applications that depend on either spring-webmvc or spring-webflux. Such applications must also have a registration for serving static resources (e.g. JS, CSS, images, and others), or have an annotated controller that returns an org.springframework.core.io.Resource. Spring Boot applications that depend on spring-boot-starter-web or spring-boot-starter-webflux are ready to serve static resources out of the box and are therefore vulnerable.

Spring Framework versions 4.2.0 to 4.2.1, 4.0.0 to 4.1.7, 3.2.0 to 3.2.14, and older unsupported versions are vulnerable to a Reflected File Download (RFD) attack. The attack involves a malicious user crafting a URL with a batch script extension that results in the response being downloaded rather than rendered and also includes some input reflected in the response.

Applications that build a Content-Disposition header value from untrusted input may be vulnerable to HTTP response splitting when the input is a malicious file name. Affects Spring Framework versions 7.0.0-7.0.8, 6.2.0-6.2.19, 6.1.0-6.1.28, 6.0.0-6.0.30, 5.3.0-5.3.49, and 5.2.25.RELEASE and earlier.

Spring Framework applications that use Spring's data binding infrastructure to apply user-supplied property paths onto a target object may be vulnerable to a Denial of Service (DoS) attack.
