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.

Spring Framework could allow a remote attacker to obtain sensitive information, caused by an error when handling the Expression Language. An attacker could exploit this vulnerability to obtain classpaths and other sensitive information.

Common Vulnerabilities and Exposures assigned an identifier CVE-2010-1622 to the following vulnerability:

SpringSource Spring Framework 2.5.x before 2.5.6.SEC02, 2.5.7 before 2.5.7.SR01, and 3.0.x before 3.0.3 allows remote attackers to execute arbitrary code via an HTTP request containing class.classLoader.URLs[0]=jar: followed by a URL of a crafted .jar file.
