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

Both Spring Security 3.2.x, 4.0.x, 4.1.0 and the Spring Framework 3.2.x, 4.0.x, 4.1.x, 4.2.x rely on URL pattern mappings for authorization and for mapping requests to controllers respectively. Differences in the strictness of the pattern matching mechanisms, for example with regards to space trimming in path segments, can lead Spring Security to not recognize certain paths as not protected that are in fact mapped to Spring MVC controllers that should be protected. The problem is compounded by the fact that the Spring Framework provides richer features with regards to pattern matching as well as by the fact that pattern matching in each Spring Security and the Spring Framework can easily be customized creating additional differences.

Under some situations, the Spring Framework 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 is 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.

An issue was discovered in Pivotal Spring Framework before 3.2.18, 4.2.x before 4.2.9, and 4.3.x before 4.3.5. Paths provided to the ResourceServlet were not properly sanitized and as a result exposed to directory traversal attacks.

Pivotal Spring Framework before 3.2.14 and 4.x before 4.1.7 do not properly process inline DTD declarations when DTD is not entirely disabled, which allows remote attackers to cause a denial of service (memory consumption and out-of-memory errors) via a crafted XML file.

The Jaxb2RootElementHttpMessageConverter in Spring MVC in Spring Framework before 3.2.8 and 4.0.0 before 4.0.2 does not disable external entity resolution, which allows remote attackers to read arbitrary files, cause a denial of service, and conduct CSRF attacks via crafted XML, aka an XML External Entity (XXE) issue. NOTE: this vulnerability exists because of an incomplete fix for CVE-2013-4152, CVE-2013-7315, and CVE-2013-6429.
